Joseph Audio demo's their speakers at Audio Shows using Bel Canto and Hegel. AXPONA is in Chicago this weekend, it will be interesting to see what they use to demo, most likely Bel Canto.
I have Joseph Audio RM25XL M2's, sounded nice with Bel Canto, but sound amazing with Hegel power. I have the Hegel H300 and 160, both integrated and sound amazing with my JA speakers and my Dali's.
