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 would think you would prefer this sound based on previous posts such as this:

>>i like a dull, veiled, laid,back, boring sound capable of putting me to sleep. i hate treble and i don't like detail.<<

Change of heart?
BTW it's "effect" not "affect"
Roy Harris: You offer no factual basis for the effect you say the P300 has on the treble. It is just your opinion. That certainly is not proof. Some people may think the P300 adds energy in the treble. It is impossible to know who is right unless we explore the psycho-acoustic nature of sound and how each of us perceives music. Even then, we will only have a theory -- nothing that can be substantiated -- and what matters is simply how the system sounds to you. Besides, anyone offering advice will be "proven" wrong with more of your psycho-babble. So, ultimately, the best thing for you might be to simply disconnect your tweeters.
Read the post again Audiofeil.

I see no change in desire for a darker top.

Just wants increased ability to include the amps

If one accepts that the p300 engenders attenuation of the treble energy, which is likely not a premise accepted by all p300 owners, then it is possible the p500 and/or p1000 also attenuates the treble. Only you can decide by listening.

I once owned a PS Audio Ultimate Outlet HC, and it was my observation that when the UO was installed, the treble was less pronounced in relation to the rest of the frequency spectrum.
Wow, If the P300 is attenuating the treble, I sure don't want one. Thanks for the warning!

Interestingly this is the first time I have heard of a PS product attenuating high frequencies. :-)
hi 9rw, you are correct, i8 offer no proof other than an opinion. thank you for your astute observation.

there is no proof as to perception of sound. its called perception because its not logic.

my purpose is to find out if anyone has perceived a change in frequency response when using the p 500 or p 1000.

it is possible that i perceive changes in frequency response which are not confirmed by others.

i accept that possibility.

ultimately, i may have to audition evry component i am considering for purchase and not rely on the experiences of others, because perceptions are idiosyncratic.

Precisely.
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.
