to some degree the definition of a stereo shop is what could be termed knife edge lazy setup. In fairness to the good people at Stereo Unlimited… going to be difficult to find a more extensive set of display inventory… 

no matter where you buy develop a relationship….

If you’re considering the T66’s you’ll need to avail yourself regarding the effects of extremely low impedances (well below 3 ohms) in relation to your amplifier. 

There’s no free lunch when it comes to system compatibility in this hobby. The preamplifier and powered ATC speaker suggestion maybe your best path to the professional level of fidelity you’ve yet to experience for yourself auditioning home theater speaker systems. 

In the Link, there is info about the Clone Amp, but the info supplied by @whitstix is is well worth taking on board, especially when the Amp's owned and their pedigrees are considered.

If a stereo amp was to be considered, this is a worthwhile knowledge to receive.

Forget your budget for now.  Unless you know what sound signatures you like the cost doesn’t mean a thing.  Determine what sounds good to you based on the music you like. When you visit shops have your music at hand.  play it, listen to it across multiple types of speakers.  Do you like detail or do you like bottom end? Lastly, enjoy the ride it’s fun and “eye” opening to hear such differences.  Once you know what you like you can begin to zero in on brand and budget. 

^^ best advice right here.  People will likely recommend what they own but in the end your ears should tell you what to get.  Take advantage of local dealers and demo what they carry or go to audio shows to get a feel.  It's a journey.
