Another ADCOM ACE-515 AC Enhancer

[hjames]

I've got a pair in my AV rack in the multichannel room downstairs that have been working like champs since I first set the room up with an HK AVR and external Adcom GFA 555 amps to run the big 4341s around 2007.

They are currently slaved off the switched outlet on my Integra DTC pre-processor and control the B&K 202+ power amp for my front mains, the B&K AVR5000 Ser II power amps for the surround channels, and the HK Citation 22 (bridged to Mono) for my JBL B460 sub.

Makes that system user friendly for Emma and I through many configurations, working flawlessly every day for nearly 20 years.

I like those ACE's, but the relays are old and have possibly endured lots of abuse. Each one I've got ended up welding it's contacts together. When I took them apart, the relay isn't even rated for a full 15 amps like the literature states. I moved to a Furman M8-S for the main stack. Even it does some sort of conditioning to the AC, which I don't want. However, I can't find a single switcher on the market which doesn't condition to some degree..

I had my newer one (Chinese push-button power switch) fail once. Unplugged it and walked away. Plugged it back in later and no problem for several years. Use it nearly every day. The US-made version with rocker power-switch has never failed

I also use ADCOM ACE-515 AC which I converted for 230 v

Has worked fine for many years.
