I sat and listened. And listened. And listened.... The only thing that kept coming back to me was the word SCARY. Not sure if I have heard a loudspeaker, in the Mach 4's price category, as dynamically astute, tonally accurate and as invisible sounding. I'm convinced the Grandinote Mach 4's will flat out embarress loudspeakers a few times their asking price simply because they're as pure sounding as the driven snow, compliments of a crossoverless design. Many designers boast the most expensive and sophisticated crossover parts but I doubt, even if made of the purist materials available, they could outperfom nothing. And nothing in the signal path represents a new sense of information that poured through this listening space and in all honesty surprised the hell out of me. I sat there going through more and more songs wondering how the Mach 4's continued to allow the music through in a way that was horn-like dynamically and especially with regard to speed. Is Max Magri THIS GOOD at making loudspeakers?
