Mo-fi Ultradeck owners - popping noise from speaker upon power off


Guys, I got a mo-if ultradeck with mastertracker cartridge and I have a problem that I cannot figure out. When I turn the power switch off, I get a loud pop through my speakers. If turn the volume down or switch to another channel, then obviously I do not hear it.

I got the player replaced with another new unit and the same thing. I have tried everything - that I can physically do, replace power cord, hook up power cord to a different outlet, using different phono preamp, etc.

Does anyone else experience this? My other Project Classic SB TT does not have this at all in the same system.

I have searched the whole internet and found one post on Stevehoffman forum about experiencing the same and that person did all sorts of experimentation to no avail.

A $2500 player should NOT have issues like this. Period.

This is pretty common. I forget the electrical reason for it, but when you have a signal feeding from whatever source, be it digital or analog, into the amp, then when you turn off that gets looped back and get a little crack at the end. The lower the volume, the lower the signal, and the less of a crack.
I have that exact TT and do not have this issue.  BTW, I love this table.  Just do.  
At least if I knew the fix, I could attempt to get it resolved. Looks like the other post of stevehoffman tried everything to no avail.
BTW, none of my other components make this noise. Only this TT. My other TT is quiet when switching on or off.
