Mariusz, I have a pair of those M15 horns. You are more than welcome to give them a listen. They're probably best driven by something like your Cyber 800 monoblocks, so if you ever paid me a visit, please don't hesitate to bring them along.
I did CES with my buddy, Vytas, who is a loudspeaker manufacturer. He makes a really unique and good sounding (in my opinion) product that seemed to mate very well with the Cyber 800. I have some definite opinions on loudspeakers (series crossovers, powered woofers), and a lot of them are not represented in the marketplace with very little exception. The design of his speakers lines up very well with those opinions. We got really good feedback from some of the folks who gave us a listen, but what do I know?
