power conditioner for cd transport and dac?

Do they negate the need for a dedicated circuit or would you use them in addition to it? I ask this question understanding that a dedicated circuit would provide no protection.

I own the Purepower 1050 and have my power amp (Einstein LITD), linestage (Gill Audio Design Alana) and CDP (Reimyo CDP-777) connected and collectively the load never exceeds 19 percent under full operating conditions. It is my understanding that as it is a regenerator, a filter is not necessary nor is a dedicated line. This is an exceptional product and is the end of the road for me.

I have but 1 conditioner. BUT it has a 400va isolation transformer as part of the deal.
All lo-power stuff goes thru the iso, CD and DVD players. Also, the small dish.

Since none of those items are ever on together, I don't worry about 100db down noise migrating from one piece to another.

Amp / Sub? own circuit thru a PSAudio Soloist outlet.

Linkster, someone on another forum said that regeneraters--while they improve clarity and detail--cause a loss in texture. I suspect that this listener has simply mistakenly processed distortion, the effects of a contaminated power source, grunge--to use an all-inclusive, non-audiophile term--as a part of the music. Can you or anyone who uses a regenerater address this characteristic?

I've heard the opposite. That a certain power regenerator brand causes hyper texturing.
