First 220Pros are arriving in dealers

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

Noise like these are usually caused by DC interference and not by the gear itself.

In this case it is the gear it self and it is something that Devialet them self know about and also it is written about on there website. It is some sort of ferrite in the powersupply that vibrates if I am correct.

If it were DC on the line how come only one of my amps makes the noise and even with a DC blocker on the mains it makes the sound.

We seem to going a bit "off thread" here .

As the whole powersupply is different in the new Pro series we just have to hope that Devialet got this problem sorted out.

This is the case. Devialet acknowledge the issue but have stood firm that 'it's normal' providing it doesn't exceed a non-specific (and I'm guessing non-existent) sound level. When my unit got replaced with a new one it still had the chattering noise, although fainter than the original. Personally I find it annoying so hopefully they've eradicated it.

Have our 220's on dem, however,  anything heard to date is not the finished article - :

 Le Configurator should be updated with new models next week.

We have used the following setups:
 
For 440 setup use 400 in the config (works but power limited to 400W).
 
For 220 setup use 250 I the config but limit the power on the output settings to 220W.

I guess the software has big implications on sound so we will wait to do our listening when correct software is out. 

S

PS Both 220's mechanically silent in operation.

Does it not come with a default factory configuration / firmware?  OK, this would not allow the use of SAM, but it would at least be the 'full Pro' specification?

(which I am assuming is what SteveO listened to at Oxford Audio at the weekend)
