Strange noise after amp's off ???

Hello,

I'm new to high-end audio.
Simple question: why is there strange noise( something like "dong" sound ) from my speakers right after I turn off my int. amp ??? is it normal ? or what should I do to fix it ?

Spendor SP1/2
Plinius 8100.

Thanks,

Hi,

I've asked the dealer, and he said that it is normal...
Anyway I'll try to get a power conditioner...

Any suggestions for power conditioner under $250 used/new???
Thanks,

A line conditioner won't resolve this but the turn-off noise is a non-issue. Switching off power at the conditioner isn't any different than at the amp, but the electronics should be left always on anyway. Lots of threads on this subject are available in the forum archives. A PS Audio unit might exhibit a slow decay shutdown, but I dunno that for a fact & beside that they are expensive & inefficient.

Have you looked to see if there's anybody in there? Safety first!

Hi. I have a Plinius 8200, which is very similiar. Mine does the same thing. I wouldn't worry about it. Most of the time, I just leave my amp on; it has a stand-by mode and a mute switch, so not much signal is going to the speakers. Have you thought of doing that? I only turn it off when I'll be out of town or if electrical storms are expected in the area (then I also unplug it).

Hope that helps,

Dan
