Electronics enthusiast who started building audio amplifier since 13 years old. After decades of career hard work in various industries in many parts of the world, I manage to return to my previous life - electronics. Triggered by COVID lock down, this old trade brings me joy and memories. Something rare and precious during these challenging days.
Smoking Cigars, anyone? Mikrolampizator by Lukasz Fikus of Lampizator. 印象
Fun and cute. Russian subminiature tube 6N16B as output stage in MoOde 9.0.6 Raspberry Pi 4B music streamer. 3D sound stage is very good. Sonic signature is warm yet transparent and natural. Compared to the two tube output stages I have built, this 6N16B is faster than the Lampizator 5670 and more musical than the Audio Note 6DJ8 tube output. Highly recommended to any DIYer.

Hi Thomas, I'd be interested to try this. How would I send you my email address?
tmpchan@jethighintl.com
Which speaker is this one Whaflexxxx ? Why not AN AX-2 ? AND the amp is not ready for B&W ?
Triangle BR-02 speaker driven by Leach power amp. My DIY AX-2 is my reference speaker with 300B.
Hi Thomas, came across your interesting video on this Raspberry 1387 Dac, could you kindly share where you got the circuit board from and the essential parts for this raspberry dac. Thanks
I used standard single side prototype board for point to point soldering. The circuit is very simple hence I didn't bother getting printed circuit board. The most important component is the output capacitor which pretty much decides the sound quality. I use GAD and if you can invest more, go for Mundorf Aluminium Oil or Miflex. I buy all my components on Taobao from mainland China. If you live outside of Asia, you get buy them from Aliexpress. For north America, partsconnexion.com sells high quality capacitors at very reasonable prices. Some are actually cheaper than Taobao. After you finish building this basic one, I highly recommend you to add tube output stage. I have a few videos on this. Tube output takes the DAC to a different level. Personally, I prefer the Lampizator output to the Audio Note one. Have fun!
Thanks for insights Thomas will speak with you on WeChat thanks again

Way overpriced. I expect more than veneered MDF for that sort of money.
Excellent! 👍
The music sounds spectacular on my usually crappy tablet speakers! Wowsers! Mids and highs are exceptional on my tablet speakers like never before!
Great crossover improvement, but the overhang of the cabinet around the baffle will cause diffraction issues also the bass/mid driver could have been rebated flush. Nit picking, but you went to such lengths to optimise the design.....
Thank you for your input. This DIY is based on the original Audio Note AX Two produced in Denmark (early days when AN started selling speakers). Baffle position of the latest AN speakers is different.
MIssion 700?
Don't understand what you are asking.
Which one is best. pcm1794 or es9038pro and why
I haven't tried 1794 yet so I don't know.
Beautifull voice
what are your thoughts about the balanced clone version of which I think of buying vs this unbalanced version.
I don't have power amp or CD player with balanced interface hence I don't know how they will sound like. If you do go ahead with the full version (both balanced and RCA interface), please let me know your listening experience.
Hello! When you turn it on for the first time, do you need to press the Power button or will it turn on by itself?
There is a power press button which I need to press in order to turn on the DAC.
@@thomasdiyaudio5353 Thanks a lot, friend!
What preamp/amp setup were you using for this recording ?
DIY FM255 and FM711 mono blocks.
What output transistors were used in the 711 ?
TTC5200, 10 pieces per channel. 20 pieces matched for 2 channels.
Where can I buy this DAC and whats the exact brand name / model. I'm assuming it supports MQA/etc... I would be streaming TIDAL via USB from a mini PC. My KRELL amp also has XLR inputs and outputs.
I bought it on Taobao in China and it is also available on AliExpress. THe brand is BRZHIFI and the model is SU10. Happy shopping!
2:37 do Think it possibel to make diy crossover for Audio Note AN/E ?? By the Way thanks fore youre video Glenn from Denmark 😊
Absolutely yes. The trick here is to find the drivers. ANK sells them but are rather expensive. It seems they are produced by Scan Speak but I have yet to find the model number. If you give me your email address, I can send you the schematics of the crossover and the dimensions of the speaker for AN-E. It's on my to do list.
請問這個唱盤你覺得符合個價位表現嗎?謝謝你
I paid about US$200 for this. Inside there is a shielded power transformer with linear power supply (low cost major brand CD transport/players usually use switching power supply). One of the best deal I ever had.
Did you make this preamp yourself?
Yes, I did. I bought the PCB on Taobao, then sourced all the components and put everything together. Very satisfying with the sound quality.
Fun project
Yes, indeed. Classical example of how to apply theory in the real world.
I love this DAC because 1. AKM Chip. 2. USB Armaner .❤❤❤
hi first of all congratulation for your excellent creations and systems From your other videos i understand you have a great knowledge of preamps What would be your first choice for a solid state line preamp ? i like natural and 3D sound a lot Thank you very much gino
Each of the preamp I have built (tube and solid state) is very good with its own sound signature. If you have to ask me, my personal preference of solid state is the Goldmund 27. It pairs well with solid state power amp and probably best with Goldmund (I do plan to build one when I got a chance). I am using the Goldmund 27 to drive my vintage 40 years old Leach power amp as my TV/video sound system which I use almost every day. If you want just vocal and simple classical music, then I would high recommend Audio Note all the way. Preamp, power amp and speaker. I have videos of these. Absolutely stunning. You can't find anything else with this musicality.
@@thomasdiyaudio5353 Good morning and thank you very much for your very kind and valuable response I know Audio Note and their great sound but they are out of my league Speaking of the Goldmund, I see that there are clones both to be assembled and already assembled Personally I was looking at some Accuphase clones of which I saw in a video very good measurements such as perfect square wave response from 20 to 20kHz. If I think that I hear 14kHz at most I'm studying the Goldmund carefully, the schematic of which I found online I see it has a first stage buffer - volume - output stage Few preamps have an input buffer which I think is beneficial Thanks again and best regards gino
@@gino3286 MBL6010 also has a buffer stage. I am considering to build one for my friend.
@@gino3286 By the way, Audio Note amplifier circuit design is very simple. Component count is rather low. It's the power supply a bit complicated.
@@thomasdiyaudio5353 Good morning and thanks again for your very kind help i have seen the MBL and my guess is that is very good indeed I only listen to CDs and files as final amplifiers i am quite satisfied my obsession is the line preamp It is very important for the overall sound I really like the sound of the tubes but it's the high voltages and high output impedance that worry me My power amps have even 5K of input impedance Very low As for the pre-amps design, I'm confused by the fact that some have only one transistor, others as many as 30 I would tend to be minimalist like Nelson Pass' bride of zen who uses just one mosfet per channel! but 7 times voltage gain is too high I prefer max 3 times voltage gain However, I am very fascinated by clones of famous preamplifiers such as the Goldmund and the Accuphase I don't know whether to throw myself into an already assembled clone I'm still studying Thanks again and best regards gino
在耳机聽来己很好声, 佩服
Thank you.
Are you driving the AN AX Two with the Leach amps?
Dear Thomas, the info you post contains an error. Booth the original version of the Leach amplifier (1976) and the 4.5 version (2000) were created by the same person, the Professor W. Marshall Leach, Jr. who died in 2010. Anyway, the amp is a very good sounding one.
I'm thinking about building a lower power (50W) version of the Leach amplifier.@@thomasdiyaudio5353
What transformers do I use for these amplifiers?
AC32V x 2, 3A
32? O 36?
32@@sergiopaez5953
Hello. How does it compare to brzhifi su-10?
In my system, they sound very similar. Probably due to the same analog output design. The SU-10 AK4499EX sounds slightly brighter on the high end while the NXC02 is more all round, nothing stands out significantly while the sound quality is very good. This NXC02 costs me US$250 which is within range of the SU-10 with external linear power supply.

DA50 looks pretty much the same as the SU10 but with balance output. No idea if the chip is real or a clone while the sound quality is very good. At this price I have no complaint. Did you use linear power supply or just ordinary power adaptor?
