Thanks it's actually Wonderful when someone reviews products on UA-cam with a system that can actually produce true details of recordings. Very Rare!!! I need a lower profile OpAmp for my application in the Douk Q11 DAC with tha upgraded power supply
Witam Pana. Fajnie się ogląda i słucha filmików. One comments which Audio Maniacs should be aware off is voltage requirements of presented OPA, when 4 pcs is required. I had MuzgAudio OPA also Polish brand but my Phono Stage failed to start at all after OPA roll off. I do not faced such problems when instaling 4 x Muses03 or OPA627. So please, everyone be carefull and read closly specifications to not waste Your time and money. Kind regards from Gdynia City
Yes, ICs do require a lot less current to start and work properly. If the device was designed for rolling opamps it will usually have better power delivery capabilities, but if that's just random replacement, things can be different. That's why I think it would be useful for manufacturer to maintain a list of devices confirmed to be working properly with a specific opamp - same goes for Akliam. Dziękuję! :)
Yes, You are right, such a list would be very helpfull. However to modify sound also roll off of the fuses is very interesting subject. I have started from Aucharm Red fuses in my system and I was very happy regarding better sound, but presently using Synergistic Research fuses. Aucharm adding very nice midrange and analog sound, SR adding all frequency like you would add booster equalizer to your system, worth to try... Pozdrawiam serdecznie
@@KatarzynaJachimska I had a phase when I was replacing all fuses everywhere :) Nowadays I'm changing it only in sources like DACs, as the results are strongest, and good fuses tend to be really, really expensive :(
I’d avoid touching any pins or any conductive materials on circuit boards. While not every component is sensitive to electrostatic discharge, it’s a good habit to get into. Especially in low humidity/high static environments. If you are building circuits and need to touch the parts, that’s different and you can wear ESD straps tied to ground for component protection.
Yes, thats a good practice. Though the last time I actually have seen something damaged by esd was in 90ties, It hink all (or most of) semicondustors have protections built in now. But you are right, its a good habit to observe that precautions SO EVERYONE: DONT DO AS I DID AND DONT PLAY WITH THEM BAREHANDED!
I wish somebody would just make a bunch of wave files recording a system playing using different op amps so one can simply download the waves and see if there is a discernible difference.
Unfortunately the sound is changed as it passes through, To be more specific the blue LED took almost 60 years to create after the Red and Green but that breakthrough led to the flat screens we use today. But on the note of wave files Yamaha DSP does that I purchased there first system in the early 90s now SMSL has a DAC with 11 OP-Amps
Can you please create a summary video of where to switch op amps along the signal chain? DAC? Pre? Amp? Which component to start with first when experimenting? Let's say the DAC has a discrete OA, should I use a relatively neutral one in the amp? It would seem like overkill to just put sparkos or bursons or staccatos in every component. Help me map out my op amp rolling journey (rabbit hole). A lot to ask, I know. Sorry.
@@murshedrahman8399 Hi! That's actually on my list of to-do-videos! Along with the one about choosing the upgrade path for power cords, interconnects etc! Stay tuned! (Start with the source, that's always the best place, and in DACs that have LPF and I/V replaceable start with I/V and move down the chain - I'll cover more in the video)
That is my question too. I use a bunch of the Akliam LC2 (now LC5) discrete opamps and they sound better to my ears than the SparkoS. Bought on AliE, 20 euro!
Both are class A, so they are similiar. LC5 are a bit airier, Staccatos softer and more analog sounding, so it boils down to personal preference and matching with specific equipment. I will do a video on all of my opamps from my collection
Well you've made me get through 37 pages of that thread. I'll remember that! There's a lot of very good testimonials at the beginning, then theres a usual audiostereo flame war between hearing and measuring war parties, then we have one guy who is testing them in Topping D10 and STX setup and hears no difference, that triggers another, smaller flame war on his equipement (yes he does have a bottleneck there) then another set of good testimonials and then thread detoriates in digressions on other opamps and some random stuff on capacitors. All in all lots of fun! =)
@@k4syx I once had these opamps at my home for a while, but I wasn't even able to test them properly. In the case of the power amplifier (a few thousand euros new) they turned off after a few seconds. In the case of the preamplifier (here they were singles) they didn't even want to start. I think that the AKLIAM LC5 for 4 times less is a more interesting option. Have you tested the staccato with the BRZHifi E600? Do they withstand higher volume levels?
@@AndNaz4820 Yes they work there flawlessly. If you had exactly that kind of problems with them as you desribe, that simply means that your amp and pre were designed for IC operational amplifiers only, and their power supply sections designed for opamp rail were made for specific current limits. Class A opamps (and full amps too!) require loads of power (current) and class A discrete opamps will not work in every single device tested: case in point: Akliams LC2 in E600 were working fine only with volume range between 0% and lets say ~10% and after that they were just switching off - there was not enough current to power them. But LC5s and Staccatos are working fine in full volume range. Also look for comments from people trying to place discrete a class opamps in mobile equipment: in 99% cases it will not work, and 1% when it will work will drain battery power source in no time :)
@@k4syx I tried with this devices a lot different opamps, fact that mostly ordinary one, but also discrete burson vivid (not sure if they also A clase) and only with staccato was a problem. But ok, they need a lot (like a lot lot) current then. That also mean some people will have to return them (cos they will be not working in a lot devices, like in my case) and you have to pay for shipping two times and i saw that just one way is 30 euro. Where for 60 euro you have 3 LC5 and zero problems.
@@AndNaz4820 Well they worked in all of my devices, but yes, you can always encounter something that will to be able to power them. Similar thing goes for replacing IC opamps - there's always risk that very high quality, fast and precise opamps will begin to oscillate in specific circuit. All in all it would be nice if discrete opamps manufacturers maintained lists of compatible equipment, as f.e. Akliam doesn't accept any returns at all. (And I also love my Akliams)
You can order (with large orders!) factory matched batches. These are ordered by 1000 matching pieces, and then there's manual pair matching, hand picking transistors for specific sets. And then there's thermal coupling, but that's the icing on the cake. That probably also partially explains the price, that sized order do not come cheap...

That's obsolete advice now days

The problem is youd need qulity ADC for that, like E1DA Cosmos. But I like the idea, good thinking!
Thank you for a very good video
Thank you!
Interesting...could you use these in a crown xls class D amp ?
As long as there is enough space to fit them inside, yes. There are also other geometries available, Ive seen the horizontal version
Are those adjustable bias pots? If so, I’m surprised they didn’t put a drop of paint on them, to preclude the setting from changing.
It will not change by itself, but I like the idea, its a simple precaution!

different folks different strokes i've tried both staccato vs sparkos I liked the sparkos more, the staccato's sounded to smooth for my liking
Yes, at this level its highly about personal preference and equipment matching to get the best combination possible
How they compare to akliam opamps? I believe are better?
That is my question too. I use a bunch of the Akliam LC2 (now LC5) discrete opamps and they sound better to my ears than the SparkoS. Bought on AliE, 20 euro!

Would it work with Fosi ZA3 or V3 monos?
@@Grooverski AFAIK yes, but you have to check for room inside
@@k4syx Thanks a lot
any sound test?
No, doesnt make sense to do that on YT untill I'll get some really good microphone.. on my list.
@@k4syx What do you think.. which one speakers will fit best for them?
@@andrews4379 These are made for amplifiers and DACs, I would place them in neutral and colder sounding stuff
friend of mine swears by these, says he like them better than sparkos ss3602...guess ill have to get some now lol
Better than Sparkos. Prooven
They are seriously good and they are used in some German hi-end equipment as a base one of components
I've read bad reviews about these opamps on the Polish Audiostereo forum (btw. Staccatos are produced in Poland). I think they're not worth the price.

I prefer Muzg Audio Jfet also from Poland
@@MoizAudio May try to get these too!
@@k4syx trust me better than staccato. I ordered 10, so you have to wait..haha
