I have a passing interest in a Luxman integrated too and find it really odd that there seem to be zero credible reviews on their products and none I can find on their "popular" integrated? Why?
Sterophile and The Absolute Sound should have reviewed them at some point if they're "cult" classics with reputations for excellent sound and build no? Reviews from owners (unless consistently poor reviews) I ignore for obvious reasons. Also, there are many 505x11 listed for sale directly from Japan for 3k (non US voltage) brand new which is also a little suspicious- they need to be run with a step down transformer of course. Has anyone bought one of these versions ?
