The 105U came out in an era of harsh sounding cd's. It was Luxman's (Alpine)solution to that problem. The output tubes added warmth and gave cd's a more organic sound. I have had several Luxman players and they were all prone to read errors even though they used Sony lasers. Drawer mechanisms were problematic as well. Impossible to say which of yours sound better, but I am sure the Lux will be less fatiqueing and perhaps more musical. Just listen to both, the one you prefer will quickly become apparent.
