Probably fairer to compare to the Aria pre-amp an stereo amp. Stacked the two units probably aren't much taller than the Luxman.
Luxman 505ux vs. Belles Aria
Has anyone had a chance to compare these two integrated amps? I currently own the Luxman paired w/Dynaudio Special 25 speakers. I really like the Luxman and realize it retails for twice as much as the Belles but the Belles stuff has always intrigued me and I've never had a chance to hear any of their amps.
