Forget the thou budget @new.
The NADs will get you to the bottom of the power you asked for
I looked up ATC and found the SCM50 in active or passive versions. no '7's.
Could you be a little more specific? Sensitivity maybe? And if available as active OR passive speakers, the amps and power of the actives.
The SCM50, above has 500 RMS divided 250lf / 150 mid / 100 hf.
If you are set up for it, bi amping with 'd' amps would work wonders, if all you want is sheer power.
Usage is something you don't address, either. You'd have to redline these in a pretty large space to TOUCH the kinds of power you are after.
A preowned Krell 400xi integrated? Save up for MAC? the MA6900? is that a right model #? How about a used W4S integrated or the identical looking PSAudio GCC series? Any chance of auditioning something? Do you have any musical goal in mind? What did you hear the ATCs with that made you buy 'em in the first place?
Other than sensitivity, what makes you think they are 'difficult to drive'?
