Is an isolation transformer better than a power conditioner?

@ghdprentice Haha, I use Blue Jeans cables to great affect in my rather resolving system! Many of the highend brands use Belden cable as the basis for their own (fancy jackets and dielectrics) cables and the buyer is none the wiser! As I said, before, at a particular level of clear and transparent sound (I have that in spades) focused and deep soundstage where the speakers cease to be identifiable as the source of the sound (I have that in spades), micro detail that is easily heard vs other systems that do not resolve as well or present such sonic cues as being common to true highend setups (I have that is spades); I don't personally see how one can claim that the change was so profound that the adjectives used are so extreme. If you had a wide/deep/detailed soundstage before, claiming that it was expanded so greatly with some new accessory seems dubious to me. A collapsed soundstage to me is just that, it ceases to give you the impression of the sound coming from behind the plane of the speakers, etc. Deeper is one thing, but many would have you believe that it wasn't present before, and it miraculously now is....

Thumbs up to Equitech! A very basic sensible product. Foundational. 

What about a high quality UPS? That cleans up pretty much everything in terms of AC line noise from other electrical equipment, voltage transients, line distortion (if you have it). It puts out perfect sine wave power. Plus, it would be a lot cheaper than some of the approaches mentioned such as the Shunyata Triton, or expensive rewiring of the last inch of electrical service.

I would note that a UPS does not typically provide galvanic isolation, and only secondary surge suppression.

Now that my new dedicated AC line is installed, I am deciding on replacing or combining my very pricey Shunyata PC with a PS Audio regenerator.

The difference between running my mono blocks directly into the new line or connecting to the Shunyata that is plugged into AC is huge. I have re-evaluated my impressions of the Shunyata. The sound of the Shunyata with the new AC is spectacular.

But audiophilia moves my to try putting in a PS Audio P12. 
Anyone have experience with the PS Audio?
 

I use a PS Audio P20 for the last few years and have found it to be a great addition to my kit.  Larger sound stage, more micro detail, lower noise, also, because of the low impedance, there is more openness on loud dynamic passages.  I am using Auidioquest Hurricane power cords throughout my system and have a dedicated 20 AMP circuit to the P20.  From what I understand you can demo any of the PS stuff for 30 days and send it back if you don't like it.  I have done A/B with and without the P20 and definitely prefer the P20.
