I've owned the X0-1, 5, and 7 Esoterics, and they were/are all excellent spinners, particularly the X0-1 (in my case, modded). That said, my Marantz SA-7S1 is a cut above in the musicality department. It just has a way of disappearing into a soundstage (I know that's a weird phrase) that has eluded the Esoterics in my room. But I'm really splitting hairs. The Esoterics are fabulous machines.
