I have had the Luxman L-550ax in my system for 3 months now. This is Lux's new iteration of the L-550aII. I replaced a big system, with full blown preamp (EAR 868) and CJ Premier 140 (big tube amp) and haven't looked back. The Luxman offers a very nice sounding selectable MM/MC phono stage (I've got a low output MC cartridge, this was important feature for me), had lots of bells and whistles and knobs and meters, but most importantly for me, has 20 watts of BIG class A (t does run warm/hot) power. In my room, with the Gallo 3.5's, I can't turn the volume past 12 or 1 o'clock. The soundstage, width is maybe a bit narrower than with my old system, the depth is comparable, and the overall quality of the sound is totally dependent upon the recording as it should be. I didn't compare with Accuphase which I'm sure is killer as well. I personally use an Audio Note 3.1 external DAC with my mac mini / JK MK3 digital front end. I'd be surprised if the Accuphase "more rugged" but who knows.
