Perfect match for ATC speakers


Hi,
I'm upgrading my audio setup and have decided to go for ATC SCM 11, and now have to choose the amp.
Any recommendation for these speakers?

Thanks,

I listen to the same kinds of music as you. I auditioned the SCM 7, 11 and 19, preferring the 19. I auditioned them at a reputable dealer with Linn and Simaudio electronics and found them both a good match, with the Simaudio smoother than the Linn. (I apologize for the subjective adjective, but it is all subjective based on your preferences, your room, etc.) Put me in the camp with those who suggest you should stick with the speaker you like and match the electronics. Did you audition the SCM 11 at a dealer? If so, what electronics was the dealer using?

In any event given your listening distance of 10’, unless you listen at extremely high volume, I would not be overly worried about amplifier power. The manufacturer recommends 75 to 300 watts per channel at 8 ohms. @pani made some good recommendations. I own one of them, the Rogue Stereo 100 paired with Totem Acoustic Sky Towers, an 88dB sensitivity speaker, which are also on the highly revealing side, and find the Rogue, while relatively neutral, particularly for a tube amp, matched better with my speakers than several solid state products. And I listen in triode mode, 60 watts per channel, at about the same listening distance of 10’. No problem driving my speakers to deliver 85 dB volume where I sit, about as loud as I’ll go.

If possible find dealers for several of the brands that have been recommended and see if they will provide loaners you can take home and hook up to the  speakers. Spend a week-end or more listening to some of your favorite music using 2 or 3 loaner amps and zero in on the one that sounds best. Note that almost all of the brands that have been recommended make integrated amps at 75 watts/channel or more. I would err on the side of more power, as that will help with transient response on large classical orchestral works. 
I had an ATC power amp the P1 to drive my harbeth (similar spec to atc) and they are unsung heroes..... The sia 150 mentioned would suit really well. And don't go on first few song impressions as this combo is good for hours of sweet listening. 


I sold all my gear when I went to big tannoys with 96db and bought a luxman A class with 20w.... Very different sound.  But wish I'd keps that ATC as backup
Same, wish if I had kept the SCM7, let go due to Amplifier mismatching.Hope to try later...
I have had ATC speakers for 18 years. The Entry Level speaker line (can ATC market their products any worse?) are different animals than the ruthlessly revealing SCM 20’s with their 80 db efficiency, and are a bit less stark on the top.

First thing I would say is that you have bought superb speakers. They are not a difficult load to drive-their impedance does not vary wildly. Being an acoustic suspension design, you don’t have to listen to bass chugging out of a port. You don’t have to listen to cupped hands hoodiness out of horn drivers (I sold Klipsch back in the day).
Some of the advice here is crap. I drive my second generation SCM 7’s with a 60 watt Adcom GFA 535 II amp I bought off EBay for $100. It drives them to ear watering levels and they sound wonderful. Paired with a Schiit Saga preamp, this shows you don’t need fancy electronics to drive them.

 I have driven my ATC SCM 35’s with a 75 watt tube C-J amp, a rebuilt 200 watt GAS Ampzilla amp, or a 200 watt SST Son of Ampzilla II amp, always with a tube preamp (Cary SLP 05 with ultimate upgrade now). They sound sublime; your tweeter is smoother than that of the SCM35, as they replaced the tweeters in the Entry line with an in-house model that is not as hard sounding with poor material. Solid state amps with big damping factors give better control, and sound best overall.

 I would recommend using a tube preamp with a solid state amp of 100 watts a channel or so. A Schiit Freya+ paired with a Schiit Vidar would be perfect and wouldn’t break the bank. But please keep your speakers!!!
