I am looking at a better DAC whre I am currently using CS4397 where I am going to take off the rh v+ and lh v+ either through the Lundahl or Sowters or even cap couple to see what this does.

Hi, this is my Buffalo III DAC.

The output BAL->SE is done la Ciuffoli, with amorphous Lundahl transformers and Mundorf Supreme + teflon caps.
It has 3 selectable output channels.

It has two input channels: one Amanero async I2S USB and one S/PDIF.
The Amanero board is isolated by a Texas Instruments ISO7640 digital isolator (done the SMD board and soldering myself, it wasn't easy...)

The raw PSU is a nice and clean TIP142 emitter follower with TL431 voltage reference. The AC line is filtered (common and differential mode chokes).

The controller is a small Arduino Nano - it has enough I/O ports to control the DAC registers, select the input and output channels, control the LCD display, the IR remote control and the rotary encoder.

The firmware is based on Hifiduino, but it was completely rewritten and optimized. It has two display modes - a "normal", clutter free one, with essential information, and the full setup mode. The LCD backlight fades out after some time to a lower level and it fades in on user action.

The enclosure is a HiFi2000 Galaxy, very good quality. Front pannel milled by Schaeffer AG.

This is the best DAC I have ever heard, especially with the async I2S input.
