Looking to buy Luxman 509Z

Go look on HiFi Shark. IMO I would look for a secondhand one.

Dedicated Audio is really good---agree on secondhand unit. Also, try a demo or open box unit from a dealer. You can get some really good deals on those.

I don't think you'll find the kind of discounts you're looking for, at least from a reputable dealer with NIB units. Agree that used, demo, or FRU is the way to go for best result.

@alke1234 I bought a show demo from Albert at Precision Audio & Video in Chicago.  It was in mint condition with a warranty.  It was a very good price and he is a dealer on Audiogon.
