The Luxman electronics are superb in both their sonic performance and build quality. I purchased their new flagship model C-900u control amplifier (linestage preamp) several months ago. It transformed my setup beyond my greatest expectations and demonstrated the importance of the preamp as truly being the heart of a high performance system. You can see some of my impressions documented
here, which also contains a link to a review from Soundstage. They have since credited it with their
Recommended Reference Component award.
