@juleman -- which Luxman model are you looking at? IMO, their entry level integrated amp (505, 550) is not that great of a value for the money. The real Luxman magic happens at 507, 509, 590 level. Anything below that, you’re better off with Yamaha or Naim. I ran my P3esr’s with Naim Unitiqute for some time. Obviously, it lacked in power but the synergy was quite good. I’m sure the higher level Naim models like Super Nait will be a very good match. Good luck!
