I have no experience with Hegel, but have owned the BHKs and moved to the m900u. Initially i was disappointed with the bass on the Luxman, relative to the BHKs. But over time I've come to think that the BHKs bass, while deep and present, was less precise or a bit muddied. Again, relative to the Luxman. I'd still like a bit more bass, and the M10x addresses this. In all other regards, the Luxman, to my ear, out performs the BHKs. Detail in spades while remaining liquid, a light, airy upper end and an almost tube like treble. Not to mention soundstage, build quality and aesthetics.
(Hegel vs Luxman) vs PS Audio
Can anyone help me. Looking at Possibly moving from my PS Audio ( BHK Monoblocks and Pre) to Luxman C900 and M10 Amps (monoblocks)or to Hegel 30a amps (monoblocks) and Conductor Preamp [latest versions]. What are the differences in sound amongst these house combinations.
