I finished my 2SK60 VFET part 3 amplifier today, it's been playing music for hours now. I have the Theseus PSFLT and Nimitz FE with Tucson daughter boards from my M2X build. I also have Austin, and Mountain View to try out later. Dead quiet and sounds awesome! Has to be the easiest amp to set bias!

The crossover is built. No problem at all. Sound seems perfect with more informations than DSP. More spacial sound. Trebble are smoother and detailed.

The new ACAmp is working well sound is nice with Denon 9600 headphone

Pictures will follow later

Great product, very fast delivery from the DIYAUDIO store, thanks for making these available.

I have a two of the paper copies of Linear Audio and I really enjoyed reading them and learning from the authors. When I saw the whole set of books available on a USB stick for a fraction of the paper price, I had to jump. This is an excellent resource on all kinds of topics in the audio universe. Some articles would even be appropriate in other electrical engineering sectors (instrumentation, low-noise design, etc). The file layout is easy to understand and there's even bonus material, which I haven't evaluated yet. Overall, very satisfied!

Impressed by the kit quality. Easy and fun to build with very well explained guide. But what surprised me the most is the sound quality of this little beast. I'm planning on building a second one to run them in mono.

I'm not a fan of Op-amps, but if you're faced with no other option, the Burson V5i is perfect. The D50s is very compact but fitment was no problem.

You must run a signal through the DAC for a least 100 hours before serious listening... the result is a much better presentation of a sound stage, less high frequency hash and more realistic voice. Every passive and active device will benefit from a breaking in procedure.

Absolutely great sounding preamp...

I used the board in an Aleph J build. It's wonderfully quiet. The board has many build options and takes a little reading to decide how you want to use it. The diyaudio discussion thread was very helpful. Highly recommend.

saw some people mentioning this was their pick with the Xduoo XD05 line threw one in my basic and wow, made it warmer and fuller sounding.
drawback is that it makes it take longer to turn on and it makes a odd pop noise in sensitive IEM's.
tempted to get another too try in the cheap Douk amp with hot swappable op amps and if I can budget it my next amp will def be a Burson amp

Came in timely fashion. Clean, authentic parts. Will use them soon. Good service.

I've purchased three boards thus far with the intentions of buying more. A great product with attention to detail and quality to match.

This was my first time in the DIY world. I had no issues at all building the amp. The feeling i had first time plugging in the power and listening to my vinyl was nothing like I had experienced before. It was amazing the sound wow. Anyway am waiting for the DIY store in get more of these jewels in because i want to build another and run duel mono blocks.
Thanks for the experience.

It was 6 years since I built my tube amp 8Wpc driving a pair of Klipsch Heresy IIIs. Then the DIY bug bit me a few months ago and started searching for my next kit. ACA was in my radar but was leaning towards something more powerful like F5. The total cost for F5 was too much since I have to import every nut and bolt, especially the pricing of the chassis for F5 was too much.

Ended up getting a pair of ACA to run in bridged mono and not at all disappointed. I took time to assemble them. My daughter who is a medical student helped me too and steadied her hands with soldering for the first time in her life.

After powering up, my daughter who has astute ears to music said "Wow!!! what clarity these have". Truly, I seem to hear more with these amps. Very low noise floor. With a pair of 12 inch high efficiency full rangers simply on a 900mm folded open baffle, the sound is "baffling". Bass is limited by the open baffle design but vocals, mids and highs seem to be very clear for us.

I used thicker wires for the DC +ve and speaker outs. Salvaged from old speaker 16AWG I think.

For the LEDs I used a pair stripped from a ribbon cable.

DC IN and LEDs have Phoenix type screw terminals fitted for easier disassembly if needed.

For the common ground used a bit of silver plated 14AWG speaker wire stripped.

For back panel wiring followed my procedure to fix and wire the speaker terminals and DC that are at the bottom and then the upper RCAs, XLR, and finally switch.

For the wiring at the switch I used single length of wire stripped where required to connect the switch and finally the XLR.

All wires routed through the sides.

Fitted Blue LEDs to L channel and REDs to the R Channel to differentiate.

Beautiful little kit. The sound of the B1 Korg is more detailed.
