Power conditioners and amp dynamics???

I'd look for balanced power transforers/systems. They can yield up to 120dB common mode noise rejection while providing multi-kilovolt protection from lightening, surges, brown-outs, etc. Many have added filters to remove further noise without limiting dynamics.

Beware though, many cheap (and high priced) "conditioners do have a negative effect in certain systems. The best I've heard about are:

Exact Power

Equi=Tech - big players in the pro audio and TV industry.

Richard Grey Power - I personally had his Powerstation 400 and Pole Pig in my system and they wored wonders. I have a terrible 60/120Hz hum or buzz in my AC line and the RGPC units had my system sounding dead quiet. Of course, I have low power SET amps, so my current demands are nothing like yours.

shunyata hydra 2's are specificially made for you situation. You do have to unplug and replug after a power failure/surge but there great. I use two of them on my Mac MC501's in Fl where our power truly sucks!

Mp666, I run two sets of monoblocks( Pass Labs XA-100's and Threshold SA-1's) through a Running Springs Audio Jaco line conditioner with great benefits with no loss of microdynamics/slam/punch at all.

I posted a review on the Jaco here on the GON, which will provide the details that piece would offer you in your system.

Audioprism makes or made line conditioners of great value and they do not restrict power.
