luxman l-550axii

An L-550AXII is Luxman's current model. Before that was the L-550AX. I believe before that was the L-550AII, probably what you're looking at, if it's 10 years old. Maybe around $1500-2000 or so, if it's clean. If it's actually an L-550AXII, it can't be more than 3-4 years old, more in the $2500 ballpark, give or take.

Well, there was a time when Luxman was owned by others, and had gravitated more toward mediocre gear. I think this was during the 70's and 80's, but not positive.
Google the L-550, there are reviews out there

Thanks, riaa!
