To @robshaw have you tried other amplifiers in addition to the ATI 6002 amplifier with your Fritz speakers?
I’ve owned an ATI designed amp with 200wpc for many years, and used with with my home theater and tried it with my audio speakers. For some reason it sounded overly neutral, lacked some body imo, great for movie dialogue, and everything you’d expect for movies. When I tried it with my two-channel audio system I never could seem to be engaged with the sound as compared to my other Class A solid state or mono tube amps, fwiw. Just curious if you’ve tried other amps with your Fritz by chance, fwiw.
