Looking to buy Luxman 509Z

Direct experience with both Dan at Dedicated Audio and Albert at PAV.  Would highly recommend both for Luxman.  Given the quality of Luxman products, I would not hesitate to consider used or a trade-in as long as it's from a reputable source.

Another vote to look for a store demo.  You get a discount and you get a full warranty! The best of both worlds.

Best price I've found so far is $12,500

That's close to 15% off. What do you think a dealer should sell you a new unit for?

Dan & Matt are great to work with from Dedicated Audio! I Purchased my Luxman from them.

As a long time Luxman user I can only say be careful with vetting your purchase if you find a second hand unit online. There have been a lot of gray market sellers over the years who convert Japanese-spec 100V units in order to sell them in other regions. The quality of the work is variable but I wouldn't trust any of them.

This probably applies more to older units but I always like to bring it up just in case.
