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.

You found the fix. You always make sure the volume is down when powering off. I wouldn't obsess about it. Probably some weird electronic switch thingamajig phenomena.

If you like it otherwise, enjoy it. I demoed one just as it was introduced. Nice table. I think it would shine with a $5-1K MC cart and decent phonostage. I don't recall experiencing the pop however. 

The company will likely address it if enough users complain about it. Otherwise play some cool records LOUD.
