Has anyone built this dac?? Id love to hear comments , tweaks, or anything on the sound and construction of Juka's DAC

Construction of Juka's DAC
Mr. RainCheck,
Try it with the tube output stage. Also, you should check out the latest up sampling receiver from Cirrus Logic CS4396-7 DAC and their CS8414 Receiver. It just might fit that's my plan, the also have a component for upsampling.

The CS4396 is a complete, high-performance 24-bit 48/96/192 kHz, stereo, digital-to-analog conversion system. The device includes a digital interpolation filter followed by a oversampled multi-bit ÄÓ modulator which drives Dynamic-Element-Matching (DEM) selection logic. The output from the DEM block controls the input to a multi-element switched capacitor DAC/low-pass filter, with fully-differential outputs.
This multi-bit architecture features significantly lower out-of-band noise and jitter sensitivity than traditional 1-bit designs and the advanced DEM guarantees low noise and distortion at all signal levels.
Product Features
24-bit conversion
Up to 192 kHz sample rates
120 dB dynamic range
-100 dB THD+N
Second-order Dynamic-Element-Matching (DEM)
Low clock jitter sensitivity
Digital de-emphasis for 32 kHz, 44.1 kHz, and 48 kHz
External reference input
