Default Forgot

The digital side is the same as the Mark II, I just linked to. GIC filter is in the box due to high impedance....

Cool 1541 A Dacasarus Rex MK II

Well... Just finished the Mark II. Same digital front end as the first one. DIR9001 replaces CS8412. 2's complement, MSB first, right justified data to NPC SM5814 digital filter. I2S to TDA1541A S1 Crown dac. I/V is Pedja Rogic DDNF on a DVB-Projekt circuit board. No feed back.... Edcor 600/600 passive filter. Outstanding clarity my best DAC to date.

Its SQ is mainly determined by the following I/V stage. When that's done with a passive filter and then an AFA, its a very satisfying sound indeed with superb dynamics, natural instrumental timbre and an almost holographic soundstage.

My experience as well. The I/V seems more important then the DAC itself. None of my DAC's sound like the accepted SQ for that particular DAC in it's usual manufacturing implementation. My next project maybe based on the PCM1704....

Just to show something bad-looking.
DIR9001 + 2 x PCM1794A + adjusted Pass D1 output.
Best DAC ever.
Tried I2S from a TE7022L USB Module, but S/PDIF through DIR9001 is better.

Hi, In the end it is all about the sound. If you can troubleshoot it and mod it I see no issues. Enjoy!

PCM1794, my favourite DAC chip.

For USB to i2S conversion, maybe you should try CM6631? I think it is one of the best.

Sometimes when I see all those pictures I get the slight impression it was about looks

Yes I thought about CM6631, but I'm not sure whether FreeBSD will work with it. For Windows you need a driver as fas as I know.
