I have a Classé CAP-100 integrated amplifier and when I power it off
after a few seconds I hear a strange whistle like sound coming from
the right channel followed by the same sound in the left. I was using
this with a larger set of speakers and do not remember ever hearing
the noise, but now on a smaller set of B&W bookshelf speakers I hear
it every time. Is this something I should worry about? Is it just
capacitors bleeding off or something like that or is it a sign of a
developing problem? I am not very familiar with high end equipment
(only that I love the sound of this amp) so if this is an ignorant
question I apologize ahead of time.

Thanks,
