Power Conditioner for your amplifier?

Gentlemen

I respectfully disagree

Simply put, I would never have amps plugged into anything other than dedicated wall outlets

It seems that some people encourage the use of a conditioner on your power amp, while others think it's a bad idea. For those who insist on not using a conditioner and plugging directly into a dedicated outlet, have you tried using a conditioner to see if it improves sonics?
If so, what conditioner did you try and what was the outcome?
I've heard and read great things about the Running Springs Audio lineup. Anyone else out there plugging your amp into a RSA conditioner? What do you hear?

All I can say is after some experimentation my amp is quieter through the RSA Haley than direct to the wall.

BTW - I do not and cannot have a dedicated line.

Let me reiterate. I am not recommending all power conditioners on all power amps. I find most conditioners harm everything more than they help and most conditioners probably cannot handle big power amps. I have owned 45 different transformers, regenerators, line filters, and other devices for improving the quality of the ac coming to my equipment. All but three, I found to harm more than they helped. I mentioned the Sound Application because Oneobgyn mentioned he had one. I suspect that my experiences may not transfer to others, so I will not mention others. I have not tried the Running Springs unit.

Hola señor poeta!
I have to admit I have not tried a lot of power conditioners...maybe I should...
I am using a 10Kv I think isolation transformer which is kind of a monster, the small shop that wound it locally said it could stand easily the whole house! Thats what I want I answered! I run my whole system through it, both amps and sources, I do star wire everything from the transformer output.
Soundwise everything is more transparent, details jump at you from everywhere, no loss of dynamics at all and with my passive preamp my audio buddies said it has too much detail and not enough silences...you go figure.
Going back to the wall outlet makes everything harsh and adds two blankets over the speakers.

I have never tried the dedicated power lines directly with no Isolation transformer since I have everything hard wired of course to an independent breaker, I will give a try though...
