Power Conditioner vs A/C cables

@phantom_av,

I purchased an Elgar power conditioner many years from a military surplus sale for about 40 dollars. I used it with Carver and Soundcraftsman amps. 
It was heavy and at the time we were moving, so I gave it to my best friend. I don’t recall the model. I don’t think I appreciated the sound enhancement it provided during the time I owned it. 

I'm with ghdprentice. If all critical listening could be done late Sunday nights, regeneration and fancy power cords would hardly be an issue. 

note on some comments above.  IMO the gold standard for a real, practical power conditioner is an industrial isolation transformer.  if oyu get one in the 2 kilowatt range, it will deliver plenty of transient power capability, will eliminate and DC component, filter out HF noise and reduce/eliminate ground noise.  Yes some series filtering is also helpful - i do it.
I would in fact argue against buying these form high end firms and get ones that meet medical requirements.  Just like I did.  The put another filter between your analog components and the dirty switch mode power supply stuff, bane of our AC lives.  Thes put noise "backward"to the grid and the rest of your house.

You need both you will be amazed when you get the match right to each component in your system it is like buying a whole new system.

I use AC regenerator and aftermarket cables from a guy on this site (acoustic bbq) and both made a difference. The regenerator made an enormous difference though.
