RE: Thanks Guys

Julian,

Sorry, I missed this post earlier.

This was discussed about 1 1/2 years ago in the cMP mega-thread... see here:

I tried this with my Antec 430 computer power supply & found very useful sound quality improvements... but also found an 'edge' to the high frequencies that I guess was the signature sound of the Panansonic caps I was using. When it didn't go away with break-in, I then tried the linear-powered PicoPSU solution discussed here:

and the linear supplies for my HDD, screen, and USB's discussed here:

I realized that while adding bypass caps at the computer power supply power plug is a worthwhile upgrade, the added performance of linear-hybrid or fully-linear supplies is so MUCH higher that adding caps on the ATX-24 and P4 plugs only make sense if you are severely cost-limited or ability-limited. Or in other words, if you can solder well enough to add caps to the plugs, you can assemble the linear-hybrid supplies.

My 2 cents.
