Re: above JoeHernandez statement between the Pioneer and the older Fisher. Pioneer products IMO (I own one of their AVR surround receivers and other items in the past) are gimmicky over high performance or sound quality. The Fisher amp/receiver would have been made more toward making good sound v. the Pioneer. It doens't surprise me at all that this was your experience.
As to the Levinson, I did a quick hook-up of my 334 Levinson amp to the Katana 2s and there is more notable air, focus and better soundstage than with the other amps I used as referenced above. This is prior to taking the time to set-up best placement of the speakers and with my other speakers still occupying their space (which negatively impacts the Gemme's performance as it all sits right now). I will listen and tweak the set-up this weekend and report back my feelings of the Gemme's with this equipment and even a mini comparison between them and my Wilson W/P speakers.
