amp is a Luxman L-550AXII, but sadly I’m unsure how to explain the
differences between it and the many other amps I’ve owned. Fortunately
there’s no shortage of reviews to be had by googling, all of which are
pretty much raves.
Suffice it to say that it’s the best amp I’ve owned, including gear that cost between two and 3 times as much. Being a Class A device with only 20W (in Class A; it does of course transition into Class A/B when pushed hard) speaker matching is something to keep in mind and you wouldn’t want to pair it with, say, 83dB/4Ohm speakers. uilder3141 posts01-21-2019 10:44pm
The L-590AX is 30W/channel Class A into 8 ohms, then switches to A/B. It will actually put out over 90W/channel into 8 ohms, and nearly 160 into 4 ohms.
I have looked on Luxman's website and have not found anything in the specs that states either the L-550AX or the L-590AX transitions to class A/B when driven beyond their 20W and 30W respectively.
I have had a L-550AX in the past with Harbeths and found it lost dynamic when driven to higher volumes.

590AXII is 30W Class @ 8 ohms. Has the classic Class A sound with a nice midrange bloom. Just note it runs out of steam pretty quickly so a fairly efficient speaker is a must IMHO.
