HTH,

Did you build up linear supplies or buy them? If you bought them, which ones?
THANKS!

Hi Greg
I am using 2 numbers, off the shelves linear power supply from Mouser Electronics.
Sola/Hevi-Duty SLD-12-6034-05T(12V & 5V) for CPU and other devices.
Sola/Hevi-Duty SLS-12-034T powering the 150W Pico for the mobo.
These are run on separate lines. Power inlet are through Bulgin IEC BZH01/Z0000/01(with switch and fuse). Used of these power inlets with Hi-Fi tuning fuses yield a better sound than direct connection to wall socket , the most evident was the tactile sensation in the bass not previously encountered.
These might not be the best but have to make do for the moment pending a better build. But I had ran these continuously for 40 hours without any problem.

Thanks. I've been looking at commercial linear supplies to use as the basis for an easy fully linear setup... WOAH, these things are expensive!
While my home-built linears don't have much less cost in materials, I can use very premium parts (Jensen 4-pole capacitors, good soft-recovery diodes) in them... and my experiences so far strongly say that sound quality is related to the quality of the supply and it's parts.
I was surprised when I heard the sonic signature I associate with various capacitor types (Elna Silmec, Panasonic FM and FC) when they were used on either the computer supplies or the 'dirty' (harddrive, USB, and screen) supplies. I don't have an explanation for this, but the sonic results were clear.
Still, a commercial linear setup may useful.
