I agree with HumanMedia -- Power line conditioning is a big plus to add to your mentioned list of non-warranty voidable tweaks (high performance power cord upgrade and vibration control footers). IME, clean power does wonders and should actually be considered a "fundamental must-have" rather than a tweak. While a chosen AC delivery system can be tweaked in various ways, it should at least begin with some form of basic line filtering and isolation of digital gear from analog gear...

Isolation of digital and analog...in a reciever - Carl G 19:23:40 01/09/09 (2)
Question:
What would be a way to isolate the receiver which gets digital signals from the DVD player or PC ?
I have several isolation transformers, but, I figure plugging a receiver/amp directly into the wall is the best. I don't own a heavy duty purifier that will handle the amp.
My system will essentially be a receiver, a CDP and probably a HTPC.
I do have a PS 300 Power Conditioner for my CD Player, but I dont think I can swing it for the DVD player...its in another room.
I was also reading about the 193M choke maneuver.
Any thoughts on better isolation than an isolation transformer are appreciated.

  Depending on the sonic performance of the particular isolation transformers and the isolation transformers maximum power capacity, a DVD player and PC can be plugged into isolation transformers for digital isolation. You can then plug the HT receiver directly into the wall -- however, at least some basic filtering such as the Auricap Tweak or the Hammond Choke Tweak may be a worthwhile effort to help provide clean non-current-limiting AC for the HT receiver -- I'm a firm believer in filtered AC for all AV gear, including power amplification. YMMV

    Agreed. Which is what I have done. Digital front ends on isolating transformer and power amps and receiver in to the wall with Hammond choke in parallel for passive filtering.
