Krell KSA100 doesn't stop upon shut down?

Hi,
I own a KSA 100 MkI and when I turn it off the sound doesn't stop immediatly but keeps going until vanishes after 20 secondes or so.
Any idea what that could be?
Anything to worry about?
Please note that this amp, which has been recently serviced (capacitores replacment, bias setup, etc) by a Krell expert, doesn't heat up very much either.
Thanks for your help.

Like Brf said, normal and nothing to worry about.

IS this common for Krell or everything? I have never had an amp keep playing after the power is turned off.?

Actually, that's an indication that you have big capacitors...since they are holding the charge. When all the power is expended, it doesn't work anymore.

This happens with my SS mono amp and VAC Sig MKIIa preamp ... perfectly normal.

Well, when I turn on my Classe amp there is a slight delay before the amp is ready to play (I can hear a click inside the amp - like a relay closing) So, when it is turned of there is also a click noise inside (about 2 or 3 seconds) after I flip the power switch. I think once you push the power button of, it must seperate the output from the input. I always turn the amp OFF before anything else, but I also mute the preamp first. Maybe sometimes I forget thought- Why are you turning off the amp when it is still getting a signal?
