Something that may be a revelation, look at the datasheet and notice that as the sample frequency goes up SNR goes down...

I doubt that. You cannot beat a crystal clock

It actually uses a crystal to generate the clock. Or I should say it uses an external clock, it would not have to be a crystal.

Hey, Russ. I was looking at WM8804 the other day, and was very interested. Only problem is I think it will be difficult to source, especially in the US.

No pretty easy. My local distributer sent me samples and has buckets of them.

They need to be purchased through Wolfson's distributors, just like the DAC chips. We have a relationship with them now, so it's pretty straight forward.

Yes, I see it now. Looks very good! Should be worth the wait!

That makes sense, especially if you only sell the boards with the chips premounted.

Pretty much have to, as many people simply can't mount them.

Default Beam me up Scotty

Hi Guys

Ok i tried to read the last 45 pages and not froth at the mouth too much. I have heard wolfson dacs spoken of with regard.
Ok i admit to having the ambition to build a tda 1541a dac non o/s with tube outputs
Could someone bring me up to speed as to
1. how feasible to output to a tube stage?
2.is oversampling de rigeur? or can that be customised
3.any experience on the sounds of 1541a vs wolfson dac?
I would appreciate anyones insights into this particularly promising thread
Regards
Nick
