There's a Cinepro 20 Line Balancer for sale right now at less than 50% of retail, on Audiogon. I have one, and it's far better than the API Power Wedge I now have in basement storage. If you can afford $850 (a guess from memory), you can't do better. An idiotically lukewarm Stereophile review has kept this conditioner from being as popular as it should be. It splits 120V into 60V+ and 60V-, a brilliantly simple idea, which leads to the lowest noise floor ever.
AC Conditioners?
Interested in a used AC Conditioner but don't know much about them. Can anyone tell me if they lose functionality as they get older? Do they where out? Do they not filter as well after protecting from some kind of surge? What are the considerations and what questions should you ask? Appreciate any info anyone can provide....
