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 unit is for sequentially timed turn on/off of amps/components, with 30 second intervals.

it may solve your problem, avoid need to turn volume down.

I have one I am not using, I could put it up for sale here if you want, for what I paid, $60. or you can find them on eBay, ... they seem to be asking more these days

if it doesn't solve your problem, you can send it back, full refund, you pay return shipping.
