Anybody tried Naim integrated with ATC speakers?

Sounds like Lindisfarne has direct experience with this matching. I do not but have never heard a smallish stand mount or floor stander sound bad with the Nait 5. The XS has more steam than the 5, and so should be able to starch the ATC's shorts for most types of music and at most listening volumes.

Naim doesn't post many specifications on their website, so it is difficult to compare peak current capability or dampening factor for their amplifiers, but from personal experience, their power ratings are conservative compared with other makes. Generally, Naim amps seem to behave somewhere in between tube and other solid state rigs in terms of speaker driving capacity per advertised wattage, i.e. they seem to do more with less.

I'd say you are at the minimum power that you would want. The problem with ATC is that they play very cleanly (low distortion) without effort and, as a result, there is always a tendency to increase the volume. A NAD M3 would go well with those speakers..

The NAD M3 seems like a nice idea.

Thanks for your answers.
On a more theoretical course: what does it mean a good quality amplifier ? (I speak of only integrated, as I never tried separate.) Might a smallish one, in wattage terms (ex: Naim, Sugden, LFD) sound better than a bigger one ( ex: Krell, Musical Fidelity) with the sensitive AND less sensitive speakers, or do the insensitive speakers always need more wattage, in order to have a good sound?

Small watts is easier to make then big watts - so for the same price a lower wattage amp will likely be better quality. However, a good amp will sound good whether it is 25 watts or 150 watts.

ATC's are a fairly easy load to drive (no nasty dips in impedance) but the 20 is not very efficient - so that is why you will need a beefy amp if you want realistic volume levels up to 105 db SPL.
