In Reply to: RE: Tuning Linux/MPD/Alsa for best sound on ALIX processor posted by ted_b on June 16, 2012 at 19:56:31:
Your post inspired me to make a very simple mod to the ALIX board. I had some Black Gate PK 50v .22u caps in my supply. I added 3 to my ALIX board. One soldered right across the power input terminal. Then one each added as a bypass to the 2 large electrolitic caps at C1 & C?. We are in the relm of tiny improvements here but I'd wager there is a little bit of cleanup in the noise floor and the cymbals.
Can I A/B the sound? No. Have I tested on a scope, no. So this falls in the relm of leap of faith. As some inmates point out, everything counts and at some level it all adds up.
I had earlier popped in a BlackGate F 50V 100u cap across the power source. It is at the exit to my power supply so only a length of 3 feet of power cord stand between it and the ALIX board. This had a distinct impact that other caps can't touch. So I expect my supply prior to this on board adjustment was pretty good. As you can tell, I am a great fan of BGs in power supplies. There must be 25 of them in the current audio chain and another dozen in my Rotel CDP.
