I want peoples opinions on best ac conditioners

you'll find different camps on this- I have had success in the past with balanced power, and have recently upgraded to the Balanced Power Tech BPT 2.5 w internal upgrades- seems to provide a very quiet background with no compromises in dynamics- bass seems tighter as well. Good luck in the search.

pricey but worth every penny

I have spent a bit of money over the years trying to
address this issue. In the long run, I believe the most
cost effective answer to the problem of AC is to install
dedicated, properly grounded 20 AMP circuits. I have
found that most amplifiers do not like being plugged
into AC conditioners. So, you need separate circuits
for your amplifiers. If you can isolate your digital from
the rest of your system, you will be better off. Right now, I have my amps and sub-woofer plugged into
2 of the dedicated circuits and the rest of my gear is
plugged into a Balanced Power Technologies BP-3.5,
which is plugged into a third dedicated circuit. The BP-3.5 supplies conditioned AC and isolates the components from each other. I can recommend the
Balanced Power Technologies AC conditioner -- it does
a great job. But, if I had a limited budget and wanted to
solve the most problems for the lowest price, I would
still recommend starting with dedicated circuits and
then see if you still feel the need for anything else.
Dedicated circuits really make a huge difference.

Hope that helps.
