What is your general listening level ?

[Axel]

Whether you own a single Devialet Expert OR even the monoblocks, I'm curious to learn what sort of volume levels do fellas here listen at ?

-15, -3, 0 or even ... +...  dB on their Devialet dial / s   ...  ?

Usually around -25, but when I'm listening loud, almost never over -10.

Thanks Axel ... 

hmmm !!  .. with my D400 & 802 D3 in a large room, i.e. 5.8 metres wide (19-Ft) X 9.15 metres long (30-Ft), I'm doing -3dB and am wondering if its too much OR do I need to move to D800 / 1000 Pro ?

I think in this case it's got a lot to do with room dimensions. I use the same amp. as you, but my listening room is much smaller than yours at 7.5m x 3.5m x 2.5m. Is -3dB your loudest listening setting? If so, I wouldn't worry about it as I read here that one of the guys gets up to,+10dB!
