Perfect match for ATC speakers

Oh thanks you all! I have so much info now to have a decision. So I will try as many equipment I can and let you know that I do.

Thanks again!

Have a look at Van Alstine. They may have what you need. Few months ago I bought a used Synergy 450 (225 wpc @ 8 ohms) directly from the AVA website to use with my EgglestonWorks Fontaine Signatures (legacy now per EW website) and am enjoying it greatly. It has transformed my listening volume to a lower level because it’s all there - dynamics, detail, space between instruments, full and robust. 

+1 active ATC.  Just do it and never look back.  Roll past the pedantic active vs passive dialogue.   ATC 19A will crush the ATC 11 (a very good transducer in its own right) and any power you will pair them with.  At least seek out a pair of active ATCs and listen.

But they do need something>120w @ 8ohm because they are measured at only 82db efficiency.

George, once again a pile of uninformed BS. Please stick to what you know( (as opposed to what you think you know) I own a pair of ATC SCM11s which I am listening to right now powered by a pair of these:

Steroephile Editor’s choice recommendation - they are a dream team made in heaven and can absolutely rock it it out if need be: nb see Martin Colloms measurements.esp into low impedance loads. You can look them up, I am too tired to bother.

t‘s all a about quality, rather than quantity.

I've never heard an ATC/Exposure combination but I've heard nothing but praise from others.
