I have mine.....
A quick general few observations from my first few hours with it...(Only last night)
I'm using B&W CM10 S2 I purchased for the job.....Agree they are over kill, but I like the noise they make. And am fully aware that the atom will not run these to there full potential no matter how good it is.
For the last 8 months I have been using a Linn DSM streamer/amp that was on loan from my dealer, having flogged my stack for cleaner lines and a one box solution. That and multi room capability as I have numerous QB's and Muso's around.
Sound - It's as sharp and punchy as any Naim gear I've heard....It really grabs the bass by the neck and controls it, punchy and fast. I liked...a lot. The mids are sublime, I'm following new parts of old songs as with the highs, I can hear symbols drift out just that tiny bit longer....it's good....really good. Even with the relatively low power against my speakers...it works.
Build - Everything you would expect from a Naim product and pretty much as advertised...Although the power point at the back is loose, it may be it's meant to be like that, I'll get back to you when I find out.
The front screen is lovely, but you kind of have to have it at eye level to see it properly, as viewing it from angles doesn't really work. It's a great thing to have.
I have a small wish list of what I'd like to happen with the screen, ie...leaving the track info onscreen, as the album art takes over after a while, few little bits like that, which may be possible, I'm still exploring.
Couple of points to note, As it stands just now...multiroom isn't working or is dropping out. I've not explored or set up in great depth, so I'm not moaning as it may be me. The app has also crashed or lost connection again...I've not checked any networks settings yet, so jury's out.
I am fairly taken with the doofer (remote). It's brilliant.
Hope that's enough for now guy's
