Switch-on/off click?

[woodstock]

Does anyone else get any kind of switch-on or -off noise through the speakers from an Expert-series amp?

Up until a few days ago, my D440 Pro started up and shut down absolutely silently.  Over the week-end, though, I did a minor re-configuration with these changes:

* enabled the XLR input
* enabled a digital co-ax input
* sett the digital co-ax input to be the start-up default (before that, the optical digital input was default at start-up)

Since then, I'm hearing a small but distinct "click" from first the right speaker, then the left, as the amp comes out of standby, just before it displays the input/volume screen.  (It sounds like a small DC offset, but I doubt that's really the explanation.)  With my start-up volume set to -40 dB, it's just about audible from the listening position if the room's quiet.  I hear the same thing when I switch off the amp, but not when I switch between inputs.

In the scheme of things it's a pretty minor annoyance, but now I know it's there it's become an itch I need to scratch... 

Interested to know if anyone else has heard this, and if so whether/how you've managed to get rid of it.

Otherwise, I'll be trying a more scientific approach to sorting it out at the week-end if time allows.

I hear it also but not thru the speakers but in the unit itself. Sounds like a relay switch. Bugs me to. My old 250 never had this issue. Might be worth asking the techs at Devialet what's up with it.
