Factors that will impact PC sound quality

I assume Desktop PC, no game, very little HD video playback, but Web, BT and NAS can be used marginally.

Hardware tuning:
  • Get the best power supply you can afford. PC- Computing 860, Corsair HX1000 makes clear sonic difference.
  • E7200 or E7300 for lowest power consumption
  • Underclock as much as possible. Using E7200, the difference between 2.53Ghz and 1.2Ghz is clearly audible.
  • Use fastest possible RAM at 3-3-3-9. RAM clock at 3-3-3-9 and 5-5-5-15 is audible difference. Prefer to get Kingston HyperX top model 4G RAM.
  • More RAM will help reduce pop/click.
  • Use as many 玄人志向 as possible
  • Use lowest clock and power consumption graphic card, e.g. ATI 4350/4550/4650 sound card only.
  • Best motherboard you can afford. I feel Asus P5Q Deluxe sounds better than Gigabyte GA-G31M-S2L
  • Overvoltage South Bridge and North Bridge for about 5%

Sound Card
  • Interface PCI-E better than PCI better than Firewire better than USB
  • Digital Output Interface: AES dual wire > AES > coaxial > Firewire > USB
  • Use computer as digital output only and use external DAC for analogue.
  • Use of Sound Card Analogue output interface is not recommended
  • Uses external Word clock > Sound Card internal clock

Software configuration and playback
  • Smallest sound card latency (32 samples)
  • Deploy "Art of building computer transport" to clean up XP. Ie. take away all unnecessary services
  • For playback software, Cplay > Foobar.
  • Offline upsampler > online upsampler
  • Native 24/192 material > Native 24/96 material upsample 24/192 > Native 24/96 > 16/44 Upsample 24/192
  • Turn off Anti-Virus and firewall (at your own risk…) to prevent pops and clicks

Optimizing XP for Music Playback with LAN and Remote Desktop (4)

Prioritize Playback Settings

1. Download “THG Task Assignment Manager v1.0” from Tomshardware.com, set cplay to CPU 1, all the rest of all services (Firefox, BT, etc) on CPU 0

2. Build a batch file to run Firefox at low priority mode “start /b /low k:\Progra~1\Mozill~1\firefox.exe" (no quote)

3. Run cplay in realtime mode, create a batch file and run the following::
@echo off
start /wait g:\process.exe -k cicsPlay.exe
start /b /realtime G:\Progra~1\cicspl~1\cicsPlay.exe %1
exit
