which power conditioner unit?

Exact Power is your best bet.

Go to ExactPower's website (www.exactpower.com) for details and an animation showing Exactly what it does to a distorted sine wave.

I live in an apartment, and run my whole system off a single dedicated 20A circuit. I have an ExactPower SP-15A (balanced power unit) daisy-chained off an ExactPower EP-15A (power regenerator). All front end stuff is plugged into the SP-15A (balanced power unit) which, as I said, gets its power from the EP-15A, along with the amp, speakers (stats) and sub.

With everything turned on, the entire system only draws 450 Watts at medium volume. With the volume control turned up to med-hi with no signal (on the phono input,) the system noise floor is about the same as an unoccupied chair.

I had one installed since I put together my Audio system and that was 3 years ago. Just started getting back into Vinyl just last year. Anyway to make a story short.... had to move audio furnitures around 2 months ago and disconnected my Power conditioner on my front ends (connected directly to wall outlet)....and WALLAHHHH.. my system sounded so good (PRAT..galore) I cannot believe my EARS. Everything you threw at it-- CD, Vinyl, Ipod..damm sounded soooo good. Bass was so pronounce and very palpable..with authority.. The sound experience was like listening to live performance 10 ft away....(to me anyway):^)).. So now I have all my electronics connected directly to 1 dedicated 20A circuit. Felt like I was robbed of good quality listening for a long time...just to share my experience.

Jolen, "I had one installed" etc. One what!?
