line conditioner for amplifiers


i have noticed the beginning of the summer degradation in the quality of the ac. LIPA is doing it again.

so, i am considering a regenerator for my vtl deluxe 120s.

ps audio is one company manufacturing such a product, including models p 500 and p 1000.

i own a p300 which i use with a tube preamp, ultimate outlet and two tubed cd players.

i like the affect of the p 300 on treble frequencies.

is it possible the p 500 and/or p 1000 engender attenuation of the treble, the way the p 300 does ?

i've just been told that Silver Circle has just developed a power conditioner based on a 5.0kVa isolation transformer, which to my knowledge is the largest isolation tranny in any audiophile power conditioning product. and IME, the reason more audiophiles don't condition their amps is b/c any active conditioning (i.e. isolation trannys) are undersized relative to the draw.

do see my review of the 3.0 PP1 for further info.

Not being as learned as all the above, I can only offer my uneducated conjecture. Is there is a possibility that the treble is perceived as being attentuated because there is less distortion at the higher frequencies when a power regenerator such as the P300 is employed, such that the listener hears less distortion, therefore less treble? Just my 2 cents.
