- Optical cables have one big advantage: total isolation from their connected source. Does that mean their use is the best digital interconnect in a high-performance system? Have a question you want to ask Paul? www.psaudio.com...
I am getting close to publishing my memoir! It's called 99% True and it is chock full of adventures, debauchery, struggles, heartwarming stories, triumphs and failures, great belly laughs, and a peek inside the high-end audio industry you've never known before.
I plan a few surprises for early adopters, so go to www.paulmcgowa... and add your name to the list of interested readers. There's an entire gallery of never before seen photos too.
Dear Paul, thank you so much for letting me understand the limitation of TOSLINK.
I just realize that
TOSLINK - 44.1kHz to 96kHz 16bit, 24bit
COAXIAL -- 44.1kHz to 192kHz 16bit, 24bit, DSD 64
Before I think TOSLINK better than COAXIAL because it is nosie proof and much cheaper cable.
Now I aware that TOSLINK can only handle upto 96 kHz / 24 bit, without DSD playback capacity.
Perphas I have to flow away my optical cable and switch back to coaxial digital cable again.
Thank you
Brian
If I want a setup for my professional DAW, and the 48khz/24bit is the sweet spot I'm working with, Toslink should be fine right?
Don't forget about BNC, which is an even higher quality connection that is similar to coaxial.
It would be so funny if you guys make a little "screen saver" for the P20 or a cup of coffee rotating around as if in a microwave!
Excellent video Paul.
BTW, opto-isolation is regularly used to enable computers to safely control powerful and potentially dangerous equipment that run high voltages and currents that would quickly fry them if anything untoward occurs.
You are the King of Digression my gawd
There is some serious audiophoolery here. I think unintentional. TOSLINK transmits at 125 mbits/sec. It is not even breathing hard at 192khz/24bit, even consumer grade and often with cheap plastic optic connects. So for hifi stereo great. For the new Dolby surround for movies it does not have a standard past Dolby Digital 7.1. So, you need HDMI for the latest DD HD or DD+.
the cables alone don't eliminate noise. they just can't pick up noise but the noise that's already in the signal is always there. quit thinking about eliminating noise, it's not possible. you can only prevent noise from getting into the signal in the first place.
It actually makes noise more noticeable (for example if the dvd has a lot of noice) since it picks up everything, the bottleneck becomes the reciever and the player.
It worked for me to eliminate a ground loop. No more annoying 50Hz hum from the subwoofer. So yeah in that regard a TOSlink cable can actually eliminate noise.
I have swapped out my standard average Toslink fiberoptic cable with a CHT Solutions product and I could tell the difference between the two. Brightened up and slightly louder than before. This is used to connect my Onkyo DV-SP500 DVD player with my Denon AVR-3808 receiver which powers Tannoy Revolution speakers. I'm happy with the outcome.
optical is very good connection if you have 2.0 system
I've seen digital reinvented so many times at very high prices when existing technology far exceeds many of the high end solutions.
The TOSLINK has issues as other than the plastic fiber. The rest of the product best resembles a TV remote control with a 40 KHZ subcarrier and limited in bandwidth by multipath and reflections in the cable.
Optocouplers have their own issue when used without line transmiters and receivers as is the case with MIDI. (yes MIDI is optically isolated) MIDI is limited to a maximum of 50 feet at a baud rate of only 31250 HZ. This is due to the cable capacitance and non linear LED load on the far end of the cable.
DMX512 for lighting control has much greater range than MIDI because it uses a balanced line transmitter and receiver with a cable termination that matches the impedance of the data cable. DMX-512 can go for 100's of feet at 250,000 baud. DMX 512 is also optically isolated as the receiver drives an opto coupler to the dimmers in the dimmer receiver section.
For MUCH higher data speeds without optical is transformer coupled at both ends of a data cable with the cable terminated into it's nominal impedance. This solution is cheap, everywhere, and very high speed. For carrying packet data it is used for Internet to connect your router to your modem and possibly desktops, game consoles, etc.
If you simply used the cable layer technology for high speed data transfer, you wouldn't hickup at 96K data rates, but blow past 100MHZ on a cheap CAT5 unshielded twisted pair cable. The technology is there. It is 100% galvonically isolated on both ends of the cable. You don't even need to use IP data packets and use something with extremely low jitter and common system data clock.
Why people re-invent the wheel to go at much lower speeds at much higher cost absolutely astounds me.
Use the proven physical layer and send your data stream.
PS audio already has a "standard" for transmitting I2S over HDMI using LVDS. It keeps the clock signals intact and has plenty of bandwidth. I question the need for added complexity. Perhaps the use of optical cable is actually to justify a fun engineering project, or as a selling point to justify the price.
I2S specification, nominal bit rate 2.5MHZ. Data Length Variable. If transmitter transmitts longer words than the receiver capacity, words are truncated. The bus uses a Serial Clock, Serial Data, Word Clock without specifying the transport layer. Appears on the surface for use inside one piece of gear and not for interconnects and is a bus topology.
HDMI is the physical layer. Definitely has distance limitations. 50 feet is considered the maximum reliable cable length. How to extend the length is a very common Google Search request. HDMI is not an open standard and requires licensing to use. Depending on version data rates on CAT 1 cable is up to 74.5 MHZ, Category 2 cables certified up to 340 MHZ. There are currently 5 different connectors used with HDMI. It is not isolated.
LVDS is a balanced cable properly terminated into it's nominal impedance signaling format with high common mode noise rejection and uses 4 voltage levels for 2 bits of data. It is not galvanometric isolated.
CAT 5e Isolated with a transformer on each end for 100% isolation. Max cable length 100 Meters. Max data rate 1 Gigabit. For network specified as supporting 10 Meg, 100 Meg, and 1,000 Meg. Does not require a license to implement.
Sorry the devil is in the details. 100 foot HDMI cable.. Marginal at best. 100 foot CAT5e certified cable is under $30 on Amazon.
If CAT5e is not fast enough, newer CAT6 is available.
Forgot to mention, with large engineering budgets for large projects, this is used by industry for concerts and multi channel recording. Google 24 channel digital stage box. If desired multiple boxes can be in sync for phase perfect clocking. This only requires a 75 ohm Coax using industry standard BNC connectors. 24 channels of Analog to Digital and 8 Channels of Digital to Analog at 24 bit 96 KHZ each is standard for between a digital console and the stage boxes. Off the shelf network cable and switches can be used for distribution. Price for the 8 DAC channels AND 24 ADC channels is under 3K, not 20K for a single 2 channel DAC.
For hard disk recording some stage boxes use a separate network to feed the channels directly to a PC for use in the recording studio and digital workstation software.
@@isettech Integra (Onkyo) has HT receivers with tbase cat cable, sends an HDMI signal up to 300 ft, to a dedicated box.
Way too much info in one go.
If I may be a bit curious and ask all of you: Would you hear the difference between a 48 kHz toslink and a 48 kHz AES connction? Or 96 kHz if you like.
Optical toslink cables itself normally go to 192kHz in my experience. But a older reciver etc can be limited to 96kHz.
My PC can sendt out 192kHz via toslink optical but my older reciver can only take 96kHz. So it seems it mostly depends on the equipment and not the optical cable itself.
Optical cable means light is going through it, so yes, the equipment around it is the limiting factor. Not the fiber optic.
Would you recommend SPDIF or TOSLINK for 2 channel music listening? If so what is a good cable under 200$. Thank you
Do ur motherboard have default optical plug ?
@@freaks238 It has a built-in optical output yes. Most do.
The plug is on the cable..
Thank you for explaining why I was not happy with the Toslink connection from my CD to my pre amp. I thought the optical link should have been superior to cable and it wasn't in that case.
Plastic toslink cables perhaps were not made well enough in the early days when it was first introduced (early 80's) but since then manufacturing techniques have made them to be very good transmission lines. The SPDIF protocol meant for consumers itself is the limit on the specified data rate, not the cable itself. It was designed before all the multi-channels we now have. The similar professional standard AES/EBU SPDIF can use optical cables and be any data/sample rate. They do not use plastic cables simply because the loss is greater over a studio's typically longer runs. The 2, 3 or even 4 feet normally required for home audio installations is NOT a problem with plastic optical cables.
Posting this if it helps. I had static coming from the adapter Toslink from tv to old receiver and I solved it by programing the audio options on the tv by pressing tv+ optical option just optical gets static. Hope this helps.
Computers, or desktop computers are extremely noisy AC wise. Considering everything inside them is DC voltage. Take a non-contact AC voltage detector and within 2 feet it is going nuts.
I use a hospital power filter to filter 100db of common/differential noise from 150Khz to 40Ghz, will it help?
I just want to make a comment on the cost of a DAC since it seems to be a source of ridicule. As someone who spent $4,000 on a Koetsu phono cartridge back in 1992, the equivalent of $7,000 now, I appreciate the value of the front end of a system. The two most important parts of the playback chain are the transducers. That is, the source, be it cartridge or DAC (it's not a source if it's not yet analog), and the speakers. Spending a lot of money on amps and cables is a waste if the first and last stages are not right. My turntable system, if you could still buy it, which you can't, would be around $15,000. My DAC, which you can still buy, is also about $15,000. My DAC is the equal of my turntable, and this is the first time since digital was introduced that I can say that.
So, Paul, go for it. Make the best DAC you possibly can. (And the best speakers too!) Then take some of that technology and trickle it down to the more affordable DACs in your line. Not everyone can afford the BHK Monos. That doesn't mean you shouldn't make them.
Me too, love the design of your products.
hi Paul I really enjoy your video. I never miss any video you upload. Can you please make video on hdmi vs optcal cable whichi one is better ? thanks a lot
i run toslink from my mb connection on my computer to my klipsch heratige " the fives" and sw121 sub set up and it sounds awesome for a 2.1 set up
I'm excited to hear about the TS-DAC, Ted is brilliant and giving him creative and financial freedom is exciting to think about, what's the ETA for this dac?
Are there optical for music, and optical for movies?
I purchased the pearl one from AQ and sound so clear and clean but lacks bass compared with others
Great video, love it when I learn more than I was expecting too. Keep up the good work.
This needs to be said
Maximum recommended length:
USB 16ft 5in
Ethernet 100 Mbit/s 100 meters
Fibre 100 Mbit/s 2 km (100BASE-FX)
I wonder how galvanically isolated USB interfaces compare in regards to noise removal, such as in Schiit Audio's Unison USB.
The quest for sonic nirvana never ends.
So, Toslink optical S/PDIF is limited to 24/96 . What is IEC958 limited to?
These are the same thing.
Exciting information. Great innovation
I love your non-answers!!!
Was the signature DAC ever bought to market? I don’t recall seeing it? What happened? @psaudio
MR PAUL I wanted to ask if you would recommend a different amplifier to drive my 12" DVC subwoofer/s in my car than a d class mono block amp?
How is your pricing actually working? You are going to charge (in UK) roughly £25.000 for a DAC while 2 BHK 300 monoblocks are £30.000 (+ £6.000 for BHK signature pre-amp)?
I thought that Chord Dave at £8.500 is insanely priced but you beat them 3x!!!
Hai My Speaker optical digital audio in available but my led digital audio out only how to connected
Use the Audioquest Optical Forest on my Cd player.. It's really good, got it for free from my hifiklubben store.
0:56 Hey! It's Cal Worthington!
I find toslink cables make a difference, in a more expensive cable there are less reflections and that creates jitter (imperfections in timing) and I hear stopping of notes way clearer with a better cable, just don't buy $2 toslink cables.
Also, the most dramatic difference is found in SPDIF sources, not all sources sound the same. You may find a bluray player with toslink out sound different than a bluesound node 2 or a chromecast audio. It also can be differences in the transceiver that sends the light.
Toslink is a way to cut distance between 2 devices, if the source device is crap, it won't come some magic at the other end.
Can the PS sprout take RCA cable or does it have to be optical cable only?,
Sorry I have a CD player but my main pleasure is vynal
If you wear hearing aids------ none of this matters.

true, I hope they find a cure for hearing damage.
Paul, big fan here of your videos and your products, though i cannot afford them, and now two new exciting products coming up! But $20k for a DAC?? Anyway more power to you guys.
Formula1 racing is great to watch and listen to but have you ever tried to buy a F1 Team........
Considering the enormous quantity of research and development that goes into statement pieces like the DAC Paul mentions, in addition to the small production quantities that such products tend to be sold in, and the often considerable costs associated with bleeding edge parts, it's often a wonder such products can be produced without incurring a loss. Keep in mind that every Lexus LF-A and every Bugatti Veyron sold was sold at a considerable loss to the parent company in spite of their respective heart-stopping asking prices. Take a look at the Boulder Audio's digital player and DAC combo for example. That product costs well over $60K for what is likely to perform uncomfortably close to the same high standard as PS Audio's upcoming mega-DAC, although Boulder's exquisite CNC machined chassis (aka the rack jewelry part of the product) is in a class of its own.
Karl Bartelt apples and oranges. Listening to audio is not a quantifiable race.
For 20 or 30 k.. i expect to hear things that are not even there..
Keep in mind that there are cheap optical and high quality optics
Cables
geez, 1600 buck for a power cable?
maybe the price is so high because virgin redheads essamble the cables on fullmoon on every first saturday (when Jupiter is in sight)
Yes they are also handwound by albino miners in russia.
Just FYI, both coaxial SPDIF and AES3 are both inductively coupled at both ends. There are no ground loops as no grounds are shared. Both schemes as well as optical SPDIF are fully digital and thus immune to noise. Balanced AES3 just improves the noise immunity with respect to the digital cliff - meaning longer max cable lengths. So no, optical does not mean = higher quality.
watch the signal if you bend 'em
can you please help me fit my home theatre in my room perfectly
go to their website... under resources, find ROOM CALCULATOR
No, they don't!
I wonder why they still use optical connectors. Never any good sound from them. Your new product with separate digital and analog on better quality optical connection sounds interesting. Only I suspect the analog part of it still be the most critical component
ernests Sorry to burst your bubble, but unlike Paul stated, there is nothing analog about optical transfer. Really... nothing.

That one expensive microwave oven. I'll take one :)
"usually limited to about 96k, so if you want to do high resolution audio, they are not a good way to go.." So I guess 96k isn't considered hi res anymore? Ha!! ok....
A few points here about fiber interfaces. Agreed, TOSLINC is junk. It's a plastic fiber. While it does offer galvanic isolation, it's rare that any consumer system will actually benefit from that. Too many other ground paths to make much of a difference. Next "half a mile"? yes, multimode fiber can easily do that. Go with single mode and you get 50-100 miles! So in your new product just use a Multimode SFP module and that will keep the costs down. Take advantage if the billion dollar IT industry! They are what makes these devices affordable in other electronics applications. But one problem with fiber is jitter. Fiber interfaces inherently have higher jitter than electrical interfaces. It's going to be trade off between jitter and noise in your upcoming split DAC. Due to all the other necessary ground paths, I would probably go with an electrical interface like balanced I2S which you have successfully implemented over an HDMI cable. But hey, I'm sure you will test both and pick the best option.Just keep in mind, fiber is not the panacea many like to think. It's great but not without some of its own issues.
heh i was actually thinking of how absolutely nuts it'd be to use single mode fiber for a dac. excessive to the point of wastefulness, but still
Yes, even multimode is overkill is this application. A balanced I2S link is about as good as it will get.
Yes fibre optic cables are shit, they are so shit they use them to send data all over the world. (At the speed of light)😂
@@r423sdex You misunderstand. I was saying the plastic fiber cables used in consumer audio are of poor quality. Of course the glass fibers used in commercial IT and for worldwide communication are not of the same class.
what is jitter? what does that sound like. does anyone know or y'all just assume.
Might be 20k, maybe 30k 😆🤣
If that P20 could speak.
You are awesome 👌
So how is analog box pure analog if ur sending a digital signal to it?? Lmao
Gregory Digital Audiophile because it’s converted to analog...
Not sure but if you want the cables money definitely seems to eliminate out of your pocket to get them lol
Analog switches inside a server? I don't follow you. Do you mean transistors operating in their linear region? Or the idea that 'digital' is more of an abstraction than a physical differentiator?
I have often wondered why optical links haven't caught on more in consumer stuff. Enterprise computing equipment use them quite a bit, even for relatively short runs. Obviously they're not concerned about audio fidelity, but bits is bits, and noise is noise; too much of the latter can make getting at your Oracle database just as difficult as getting good sound.
"Analog" was used here to avoid the word "digital", obviously because of it's negative connotation in regards to audio.
Nevertheless, any device that is either on or off is digital by definition. Even if the switch passes an analog signal. Anyway... there's nothing analog about optical transfer. Neither does an optical connection induce noise.
If you wanted to have some fun, you could drive a class D amplifier with an optical input. You just need a detector to drive the FETs from an optical signal. Really no different than how they do it now. The advantage is that you would go directly from the digital domain to the amplifier output stage, bypassing the analog circuitry used to modulate the FETs. The optical signal would directly modulate the FETs.
EFormance Engineering An interesting thought. Although, to my knowledge a triangle wave is required to drive the FETS. But changing a square wave of a fixed frequency to a triangle is not exactly new ground or very hard to do.
If you use a MOSFET driver chip, it'll take a square wave and handle the dead-time appropriately. These chips also do high side switching of N channel MOSFETS, so you can have the same N-channel FET on the high and low side of the rail, to ensure perfect balance. One of the problems of driving a MOSFET (other than needing a low impedance driver) is the overlap between high and low channels. The purpose-made driver chips have a 500ns deadband to prevent both FETs from conduction simultaneously and generating excessive heat. The combination is awesome, because you can get high current, low resistance MOSFETs pretty easily and make a driver that dissipates almost no heat. I built a dual H-bridge driver for a stepper, and for the intended use it didn't need heatsinks on the FETs because the resistance was so low.
EFormance Engineering Thanks for the heads up. I recently repaired a JBL sub, which got me up to speed on the basics of ClassD. But that still leaves me with a lot to learn ! Especially the details and the current state of the industry. Although I did read that improvements were made in switching technology !
I do understand that no heatsinks is quite an achievement. Wow !
Looks like a microwave oven! 😂😂😂
Please don't eat a bug.
I was amused at the thinking behind turning a digital cable analogue, it seem PS Audio want to change the modern understanding of why digital signals have better integrity than analogue on its head; probably to convince their analogue nutters to buy the system), PMSL!. "We lower the highs to they dont saturate"), but thats the whole point of digital Paul; so the 1's and 0's are as wide apart as possible preserving signal integrity. That guy obviously knew electronics very well at the start; then as the years passed he has listened to so much drivel hes actually started to believe it.
Plz replaye
30 K $ DAC ? LOL
Yes, the crazy thing about that is that they most definitely used an off the shelf DAC chip costing less than £10, a company like this has production runs too small for customer silicon design manufacturing. So they are charging all that money on PSU and associated circuitry; a total rip off.
We, The Audiophiles don't care . We've got lots of millions of $$$ , for us must be the most expensive DAC or anything in AUDIO Equipment , otherwise it doesn't sound RIGHT !!! Especially we love extremely expensive cables , any cables in fact . The most expensive the better . LOL
Suzy Siviter so, you’ve seen the logic diagrams have you ?
MrSteamDragon: I dont need to see the logic diagrams, its common sense for anyone whos even visited a silicon manufacturer; they wont touch manufacturing unless its in the 10's thousands for it to be economical. They probably got the chip from the likes of Analog devices or Wolfram; thats where the real performance innovations are.
Especially since I got a really great one for only $15,000. And it's worth it.
Mmmmm mamma mia lmaoo
Now I am starting to get very annoyed by Paul.
He is constantly selling [yes, he is selling] equipment that is WAY beyond what is necessary to produce absolute high-end audio. He is talking about PS design approaches that produce differences that can ONLY be measured by top-end electronic diagnostic equipment. In terms of what the sum difference is to any human, it is totally utterly undetectable.
PS makes its money from gullible people with little or no scientific/electronic knowledge,who have lots of money to spare.
[I am from an electronics engineering background]
Peter Hodgkinson I can not afford this stuff either.but this is like getting mad at Alston Martin for making very expensive autos
Would you prefer he only references Sony? But that would make no sense. In case you missed it, he OWNS the company, I think he is entitled to talking about his world when he is sharing, er, his world with us.
Peter Hodgkinson Welcome to the world of "hi-end" audio. Check out vandenHul cabling. PS Audio are not the worst of the bunch.....
Similar things are not the same: If you want advice on building high quality digital signals cables, ask a digital signals processing scientist since, you know, they have specific expertise in that. If you want to "measure" what sounds great, ask your ears. Said differently, it's like asking the dude who designed a Porsche engine how to drive fastest around the 'ring - that's not his or her expertise. Or asking a race car driver about a new engine mod - not their expertise. Seeing a pattern here Pete? The fact that you're an "electronics engineer" qualifies you for exactly nothing here - and the fact that you don't know that is a 20lb cherry on top of your ignorance sundae.
Gruss Gott Tsss... assumptions.
I simply use Profibuskabel for all my cables. It's meant to be used at 1.5Mbit/s and someone told me that digital is in fact also analog, so no worries there. Besides, it looks cool as fcuk.
😎😏😅
Ok, so TOSLINK cables are plastic and not glass fibers? I don't see how that can work, but for for the sake of argument, let's go with that assumption for the moment. So here is the question: TOSLINK are the only optical cables available to my knowledge for audio......unless you know of others. So are there other optical cables available for the consumer?
Good luck selling those $30k pieces. I would not want to be the manufacture investing in gear like that in this economy or what it is about to become. Diminishing returns city!
Paul got sidetracked once again hawking $20K amplifiers and DACs, this time. I don't come here to gush over your gear rather the technical details that have -0- to do with PS audio. TOSLINK is still around, BTW. XBOX
I'm surprised they aren't using Ethernet to communicate, instead of a big ole optical fiber setup. Differential signaling methods are just as noise immune as optical. The TOSlink physical connection is used on everything from home audio to million dollar servers. It's call fiber channel. It used to be exclusively over fiber, but they do fiber channel over differential copper too. It's basically SCSI over fiber.

starshipeleven Analog logic is non-existant. Anything that is either on or off, is digital by definition. Even if these switches pass an analog signal. It is merely Paul's way of avoiding the word "digital".

Shawn Hicks Thanks... interesting read. But I highly doubt this is technology implemented in PS Audio equipment, or any other contemporary equipment for that matter. As far as a quick read goes, said technology is basically obsolete.
In modern guitar amps LDR's are commonly used as switches, to avoid pops and clicks.
They do cause some distortion and do wear. Not great for hi-end audio obviously, but that is the best example I can come with for an analog switch. The control of these switches however is fully digital.
@@Tubetinkerer Everything physical is in fact analog, a binary digit is defined by measurable thresholds of electromagnetic states. Logic is abstract and intangible, however the systems that execute our calculations are susceptible to corruption from physical effects.
starshipeleven "Dont go overboard" indeed. C'mon guys, we are talking household audio here.
It's not realistic to think that PS audio implements analog logic or quantum computing to enable or disable an audiosignal. My quantum computing remark was wholly tongue in cheek.
