Power Conditioner for your amplifier?

General rule is to never plug an amp into a power conditioner.

There are a few exceptions, but a well designed amp doesn't need power conditioning (at least nothing that most current third party providers offer).

The more poorly designed power supply in any component. ..the more you need (or will notice) improvements by conditioning.

^^ this is incorrect, here is why:

Power conditioning if done right will have the following aspects:

1) regulates line voltage
2) prevents high frequency noise (most electronics should be immune to this BTW)
3) prevents low frequency harmonics (the most deliterious is the 5th harmonic which can cause buzzing and mechanical noise- Fluke Instruments published a paper on this), IOW puts out an undistorted sine wave.
4) blocks DC on the line.

I've yet to encounter a 'high end audio' power conditioner that can do all these things but there are conditioners that can do this made for commercial/industrial applications. As a result we do not recommend high end audio power conditioners for our amps as I have yet to run into one that works. Usually they cause more trouble. But a power conditioner that works is another matter entirely. Elgar is an example of a company that made such conditioners although they appear to have gotten out of the market some years ago. Here is an example of one of their conditioners that really works:

What about new Shunyata?

Burmester 948. Amazing component.

Using Audience 6 TSSD 20 Amp for my Pass 350.8 350ch sounds much better than in the wall.Depends on the quality of your unit and your power.Using a second Audience 6 TSSD for TT,preamp and CD player.
