Thank you Peter! I hope you venture back into computer music sound eventually! (I remember reading about you venturing into that before in a different thread).

I wouldn´t call it a clock trick, as it is technically and objectively much superior to the CS8412 internal VCO.

BTW, I entered this thread through the front page of DIYA and didn´t realize it was in the commercial section.

Best,
Alex

Commercial or not, any input is useful and I appreciate your advice anyway. I might even try it one day.

Can you tell more about the case material? I really like the understated simplicity.

Is this going to be offered as a kit or are we on our own with this? After I finish the several other projects I'm working on this has moved up the list. I've been looking for a high quality balanced dac and this looks to be a reasonably simple design. Thanks for posting all this.

I wanted to make the cases out of 3 x 6" aluminum extrusion but it was hard to source it locally. So instead I used 4 x 6 extrusion, cutting it in half to reduce the height. It actually came out better this way, with a ventilation slot and less resonances.

4 angles and 12 screws hold the whole structure together, it's all very rigid.

I cut everything myself and finished with bead blasting (aluminum oxide, 80 grit). Later it was sprayed with Engine Finish which produces quite durable and basically invisible shield.

I'd rather see it as a guideline for improving existing DACs, than a kit offer. Some ideas shown here can be also implemented in other designs.

Probably because the source IS a digital source.

The logic of this statement completely escapes me

improved clocking usually resolves more detail, that doesn't always sound so great - Iv'e been there before . . .

So we just don't use better digital techniques and/or better clocks as it sounds more pleasing to our ears without it ....
