Gryphon is on a another level altogether much better sounding as well as precision
and build quality .m6 brother has a Diablo 300, the 590 Luxman is pretty decent
but dynamics,detail,soundstage just not on this level
the Diablo especially the 300 is like over $20 k in seperates and more cohesive. Then any separates at$10k + each , plus you need to buy quality. Interconnects and power cords.
