First 220Pros are arriving in dealers

[Zappydev]

Any impressions on whether the power supply in the 220pro still makes the weird mechanical sounding 'chattering' noise a lot of the 200's make?

Is this coming from the actual unit or the speakers ?

It comes from the unit, my master 200 is silent but in the Companion there is a little fuzzzzzzi sound from some component in the power supply. It is only audible really close to the amp.

I had the same on the master of my D400. Happily, the Od'A is silent
