In case it looks like we've been here before, I'm not asking the same questions that I've seen here so many times before, and least not near as I can tell. I already have several surge protectors, not because I buy into the science, but rather because I buy the deals. Already have PS Audio, Shunyata, Panamax, Monster, Brickwall and Powerware.
Anyway, a tech at PS Audio suggested that for my amps, I might be happier not having them powered by AC regenerators. Possibly restricts dynamics. I pointed out that the my PS Audio and Powerware AC regenerator displays indicated that I have plenty of headroom, even with the amps plugged in. He countered that an amp draw upon a transient can be so fast that the front panel readout might not be fast enough to show that I very briefly exceeded capacity. And maybe these regenerators don't have their own capacitance to deal with it. Whatever the case, I was thinking about trying a more simplistic approach, but only for the amps. Besides, isn't it generally better anyway not to mix digital components on the same duplexes as analog?
So many of these surge protectors make claims about how their special line conditioning will help the digital and video components, etc. I don't care since this is just for the amps.
I already have two 40 amp dedicated lines, with a surge protector in the main fusebox. My electrician sank an additional ground rod recently to be safe, although he said I was technically already up to code. I have 3 outboard amps, each in the $3,000 range. All powering 4 ohm speakers, so there is a current draw. Plus I have 4 Velodyne HGS subs, and even though they are digital switching amps, I figure I should still treat them as amps. Because the amps are on different sides of the room, I will need at least 2 surge protectors. My Mirage OM5 rears speakers have BASH amps for their integrated subwoofer sections, but I don't care much about those. I'm just focusing on the 3 outboard amps and 4 Vels.
According to my PS Audio Premier, I'm getting between 121-126 volts, so I don't think I need any voltage regulation. Just simple quality surge protection. Maybe well isolated duplexes are a purchase point. Can one amp affect another?
I was looking for cheap. Maybe a Furman or Tripplite unit. There are great deals on the Monster 3500II, but I know that people don't think highly of Monster, and also that is yet another unit which seems more designed for digital, analog and video, rather than just for amps.
