I finished wiring up a new kit from AudioNoteKits - DAC 4.1 Special Edition. Worked like a champ this afternoon. I had previous issues with a bad regulator in the power supply that I had remedied earlier in the process.
The image is the DAC section to the left, I/V transformers, 5687 driver board, and the triple C core output transformers on the right.
Coax and AES SPDIF inputs, Balanced, and Single Ended outputs. Audio Note Copper film caps in the PSU and Driver board. Blackgates on the DAC and 5687 Driver board. AN tantalum resistors all around.
Very nice sound right off, good highs, low lows, smooth midrange even in my Son's system of my hand me downs, using an old DVD player for transport.
Once I finish the case alterations I need to do, I will put it in my main system with a PC server and a Halide Bridge.
This is the second kit I have built from AudioNoteKits, my first is an EL34 PP stereo amp, and both have been a joy to build, fun to customize along the way and sound wonderful.
