I had a question about my M700 amps. I’ve noticed when you plug them in and turn the power switch on in the back that I hear something, a relay?, click after a few seconds. I have both amps plugged into an Adcom ACE-515 power filter. If I use that, when it’s switched off all power going to the amps is removed. When I turn the filter on, I will hear the relay click in both amps after a short period of time. My question is, is there some circuit within the M700s that benefits from having power at all times to reduce warm up time? My Mark Levinson No. 28 preamp is like that. It’s always partially powered so I plug that into the unswitched outlet on the filter. Just curious. It’s only slightly easier to switch the system off with the ACE-515. I could easily leave that on at all times if there was some sonic benefit. If there is, it’s nothing I’ve been able to hear yet.
Thanks in advance,
