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.
@@thomasdiyaudio5353 the tube dac in this video, can also find in Taobao? Can I buy ur design when you finish the PSU?Tube Dac is hard to find, most of them are too expensive.
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.
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.
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.
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.
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
@@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
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.
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.
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.
Please note, this DAC has an annoying beug in optical mode, the coach who must change the source or the filters.The problem was sent to the seller, but he doesn't know how to fix this, the remote control is useless.Videoru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-95_RO1m_Xj4.htmlsi=U1vdFIudnMBBseO0
@@thomasdiyaudio5353 This brand is not serious, do not invest in this model, it is not serious, it is the first time that the 4499EX chip does not sound as it should, the engineers are bad.
It is a brand that is not serious, several people buy brzhifi, but the engineers are zero and the brand will not last long I regret having bought the SU10. Attention ...
I also have a 9038Q2M board (just bare board, no chassis). Sound quality is OK but nothing like this 4499. I do plan to get a 9038Pro (probably dual chip) or something in that range in 2024.
Gotham coaxial cable from CD transport to DAC. The white turntable is Project Debut Carbon Esprit. The B&W speaker is floorstanding and of course much better than Chartwell which is a bookshelf.

I was seriously considering this DAC about 2 weeks ago. I ended up ordering the Opoint DA50 unit it was around same cost but had Balanced XLR plugs which I was wanting. I’ve been happy but wondered how these 2 products would compare. Any idea if the chip is real or a clone?
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?
This DAC is surprisingly good, especially with linear power supply. The power adaptor which comes with it is OK but there is audible improvement once I use linear power supply.
Without a doubt AN components will take this to another level. However the prices are outrageous. One thing I will definitely do next time is to use Mundorf oil caps instead of GAD.
