When it came time to replace my 25 year old CJ PV 5 & Solid state amp combo a few years back, I lusted after an Ayre EX-8. As my wife let me know that was out of the question, I settled on a Luxman L-550AXII.
ive continue to be quite happy with the choice. It has a bit of the richness and depth I associate with tubes, without the loss of resolution. It’s a polar opposite of the plastic 2d sound of class d. the build is superb. Every day, after listening to much more expensive gear at work. I go home and enjoy the Luxman. At the time, I considered the 590ax II, but the president of Luxman America convinced me the power of the 550 was more than adequate for my 91db speakers. As I’ve heard it driving much more difficult loads, I do not doubt it would be good enough for the Joseph’s. It has far more current capability than the Pass, for example. While it doesn’t match the Ayre for detail, at 60% of the price, it is always enjoyable. The phono section is quite good, as a bonus!
