It depends on what you listen to. This 6010 is fast and clean. It's all round suitable for all kinds of music. If vocal is your preference, then a tube preamp is most suitable. Usually they are very musical with magical vocal.

@@thomasdiyaudio5353 which is the best (clone) tube preamp you can suggest that i can buy directly from Ali for example? budget 300 EUR max? also max 2 tubes in there or else things get expensive.. (1 rca output is enough for me)

Possible. However, I live in Hong Kong and the freight charge to UK is quite high and I am not sure if there is any import duty. What is your email address? Mine is tmpchan@jethighintl.com

Please email me for details. tmpchan@jethighintl.com

Thank you.

@@thomasdiyaudio5353 i am playing the FM255 MKll and 300A clones.. Do you have any idea about the difference between the Fm 711 Monoblocks and 300A ?

@@richardlui8914 I haven't had the chance to listen to the 300A clone hence I can't be absolutely sure. However, I think both 300A and 711 share similar sound signature while 711 has twice the output power.

@@thomasdiyaudio5353 FM 711 monoblocks just look so handsome at the appearance ! have you had a chance to try the d5 pro clone ? So far everybody has positive comments on it .. may try the Cary SPL90 pre clone and D5 pro power clone ..

Totally agree. One day when I have space, I would surely try Open Baffle speakers. In particular the DIY speaker published in Lampizator's DIY site.

@ The bad news is that many of the vintage drivers he advocates are now insanely expensive. The good news is that there are many high efficiency drivers being manufactured that are reasonably priced…even some alnico. I preferred 16ohm drivers because I could run 4 in parallel and still have a reasonable overall impedance for the amp. I look forward to seeing g what you come up with!

I bought 4 pieces from used market in mainland China. Two are in good condition while two need repair work. I had seen them in eBay as well.

I also plan on building the Lampucera as well.

@@thomasdiyaudio5353 keep us posted!

Tube output really takes the 1387 DAC to a different level. Also the output capacitor and the IV resistor are critical in sound quality.

Do you just need the schematics? Or a complete review of how this is built?

Thanks for replying. It would be great to have the schematics first but best to have a step by step. Also could u show the underside of the PCB board... because I don't understand schematics I was hoping to understand/copy how you solder pt to pt 👍. What about selling the finished board less the 1387chip to me. Look forward to hearing from u

@@johnsnowlow1883 What is your email address? Mine is tmpchan@jethighintl.com. Which country are you in? If you don't mind this is only a prototype, you can have it at component cost.

I use the CS8412 board to connect to CD transport via coaxial. The sound quality is slightly better than Pi streamer. My Pi streamer setup is 1387 DAC connects directly to Pi via the 40 pin GPIO with FLAC files on USB thumb drive.

I am planning to build an upgrade version of this standalone DAC with better components in a proper chassis. At the moment, the vocal is better than my dual 9038 Pro DAC. String instruments sound more real. Entire presentation is more natural.

I’m currently sourcing the parts for the ProtoDac. The upgraded foil resistors for DC offset are tough to find in a 430 .

@@marcnomad9736 I am using AMRS resistors which is very good. If you are willing to pay more, you can try AMRG.

Output stage is OP627, others are 5534

Triangle BR-02 speaker driven by Leach power amp. My DIY AX-2 is my reference speaker with 300B.

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

Hi Thomas, would you please share about this diy DAC information or web site? Thank you so much!

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.

Don't understand what you are asking.

I haven't tried 1794 yet so I don't know.

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.

There is a power press button which I need to press in order to turn on the DAC.

@@thomasdiyaudio5353 Thanks a lot, friend!

DIY FM255 and FM711 mono blocks.

TTC5200, 10 pieces per channel. 20 pieces matched for 2 channels.

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!

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.

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.

Yes, I did. I bought the PCB on Taobao, then sourced all the components and put everything together. Very satisfying with the sound quality.

Yes, indeed. Classical example of how to apply theory in the real world.

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

Thank you.

In the video, I used DIY FM255 and FM711 to drive the AX Two. This was when I first finished building the speakers. Afterwards, I have been using my DIY Meishu Tonmeister 300B to drive the AX Two. This is now my reference setup for vocal.

If this is the case, I should apologize for my misunderstanding and mistake. Did you build any of his amplifier?

I'm thinking about building a lower power (50W) version of the Leach amplifier.@@thomasdiyaudio5353

AC32V x 2, 3A

32? O 36?

32@@sergiopaez5953

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.

Yes, and they actually sound slightly better than the original one.

@@thomasdiyaudio5353 The Mundorf caps will make a big difference.

Yes, they do.@@ChicagoRob2
