Anybody tried Naim integrated with ATC speakers?

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.

NAD is releasing a new integrated amp that takes many of the advanced features of the M3 and places it in the more modestly priced non-Master series chassis. It is the new 375. I would hold off buying the M3 in favor of this. Very impressive specs and features the core M3 electronics. Was just announced on the new Absolute Sound website this week. There will be a $1,000 difference in price at the retail level.

I have owned numerous ATC speakers and feel you should plan at least 100 to 150 watts to properly drive the 19s. I own the M3 and can attest to its performance. It throws a nice soundstage and is fairly neutral, lacking the warmth of earlier NAD models. I am very anxious to see the new 375. I would also look at the new McIntosh 6300 amp or maybe something British like a Roksan Kandy 2. Both are in the beefy 100 to 150 watt range that Shadorne describes above and will be brilliant all rounders.

I love the build-to-value quality of NAIM and LFD products.
These are small English companies that relish old world craftsmenship, measured in decades of customer satisifaction. They deserve the great press they receive. I think they would work better with other English speakers like the new KEF Reference Speakers, Harbeth, and Spendor. ATC is of the same calibre but has rarely embraced the consumer market, in favor of professional environments. I really think that only the smaller ATC 7s would work with these amps that are in the 60 watt range.
