The stars aligned and my KEF & Luxman dealer sold a new Luxman L-509Z to a customer who traded-in a mint L-509X. The L-509X was, until recently when the L-509Z started shipping, the top-of-the-line Class A-B integrated amp. I got a great price and took it home. It's not a lot more power by the specs, though a notably higher damping factor (210 to 370) over my existing entry-level L-505uX Mk2. I notice a difference and really don't care to hear the usual "placebo effect"/"expectation bias" stuff from those who like to do that. Let me be happy for a day...I'm a machinist/toolmaker and the top cover plate is a machining masterpiece. Maybe that's why I wanted one! The old one is less than 1/2 the price of the new model, and has a couple more features. Very satisfied.
