Power Conditioners

Unless you want to roll the dice concerning system destruction via a lightning strike, you should at the minimum immediately install a guaranteed surge protector.
Anecdote: A friend of mine in Tampa who sells/installs commercial grade computer systems has seen the destruction of an installation in a high-rise office building where a bolt of lightning struck the glass curtain wall and arced directly to the system...bypassing the surge protector!
An "act of God" if there ever was one. 

I was using a Furman Elite 15i and just did a demo of the Synergistic Research PowerCell 8 UEF SE. it is night and day! The dynamics and holographic imaging are amazing. I’m actually going with a combination of SR power cords/interconnects and speaker cables along with fuses and HFTs. Just amazed at what this company brings to the table. Purchasing through Alfred at HighendElectronics. Super! Super! Seller! Oh yes dedicated circuit is a huge benefit!

As I’d expect! The SR PowerCell is $2,000 and the Furman is $450. +1 on working with Alfred on SR products. But your example wasn’t a "fair fight"....ha.

Yes I concede. I guess my point was to emphasize how important power is in the mix and I never used to think so but I’m a believer!
I have wondered about the PS Audio Regenerators if anyone has any experience with those. Probably keep the SR stuff though. Alfred has been awesome to work with.

Try the Stellar Power Plant 3 from PS Audio. Give them a call to see if it can power your whole system. They have a good return policy.

Also for a big difference, try acoustic wall treatments from GIK. Call them for suggestions.
