Have l become unstable?


I’ve always had nice audiophile quality gear and now I’m considering moving to something that’s capable of giving me an “auditory triple-bypass” if so inclined; the ATC 40 SCMA active paired with my JL e-110 sub.  I’m mostly not a volume listener, but find Buddy Guy too polite through Manley Mahi monoblocks and Merlin monitors.  Will I lose the great micro detail, imaging and sound stage depth I enjoy now?

Thanks for contemplative input.

I own a set of ATC SCM-20A active monitors. They replaced Dunlavy SCIVa’s powered by one of a variety of amps and speaker cable combinations. I never turned back. Simpler is better. No longer do I need or worry about the adequacy of speaker cabling or amps. 

Your ATC choice is a good one; I believe your will likely enjoy improved sound reproduction. But I agree with @whart, listen to your candidate speakers, preferably in your home audio listening room before deciding. 
Whart, I believe the disorder would be Neurosis. Something that many audiophiles experience.
The ATC SCM 40 are fantastic loudspeakers  and are very dynamic. The issue with your current setup is not enough power to get you the dynamics and liveness you crave.

The ATC three way have a better image, with a stunning midrange that is neutral and clean, good treble detail. 

We became an ATC dealer after hearing the active SCM 40.
