Impact to sound quality from different PC component

A summary of impact of each HTPC Hardware configuration component to the sound quality:

Motherboard Under-Clocking: Since PC is very noisy, lowering clock speed (e.g. 600Mhz) will reduce noise (RFI, electronic, etc) and thus results in quieter backgound, deeper sound stage and better resolution. Underclock is difficult and one needs to master the overclock settings in order to achieve good result, but it is critical in the computer audiophile PC.

玄人志向: Improves Punch and rhythm, reduces background quietness

High Power PSU: Improves punch

LAN or USB (without): ultra-high frequency noise level, airy feel, finest minor details, 弱音.

Sound Card hardware Latency: Reduces the latency setting ( e.g. 32 samples on RME 9632) improves focus and sound stage

South Bridge voltage: slightly increase voltage will get better punch.
