Help: Classe CAV75 problem?

Hi,
I had a Classe CAV75 (6 channels) bridged to 3 channels, and here is the problem. My speakers make a sound every time I turn off the amp. The sound is like gun shooting in Star War movie or in another words it's like a capacitor discharging (high requency sound). Called Classe and they said that it's the design problem.
So, my questions are does any CAV75 owner has the same problem or it's just my unit? Will this noise damage my speaker?
Thanks for your help

My CA200 doesn't have this problem, FWIW...

I play electric bass guitar and in the world of guitar amps this is not unusual. I own an SWR bass amp, which is one of the best on the market and it makes a very loud thump when turned off. This should in no way damage your speakers. It is a really surprising that Classe let those out the door though. I use Classe 70 amps in my surround system and they make no noise (these are really beautiful sounding amps and a really great used buy). I have also owned a DR15, a Fifteen, and a CA300, all very quiet.

My c-j premiere 11a does the say thing, though it is more of a dull thump. I think this is a not uncommon occurence with various amps regardless of design.
