I’ve also read that the Y3000 had some reliability issues. The new 3200 seems better. But compared to Luxman 509 - no contest. Luxman every day.
if you were asking about the Yamaha 3200 vs some lesser (imo) integrateds than the flagship Luxman, such as krell k300i, Cambridge Edge A, maybe a $5-6k Pass Labs, Hegel 390, etc, then the Yamaha is in a fairer fight. Ymmv
but that would be for the 3200, not the 3000
