Luxman Integrated?

I recently listened to a Luxman integrated and was quite impressed with the liquidity of the sound of the amp.  Does anyone else have experience with these amps?   I currently have all separates and a tube amp but thinking of scaling down a bit.
It's now running a new turntable, too greg. Bought the new rig from MoFi, it's superb. Not the big money that some folks spend, but I'm impressed.
Nice write-up on the 550, Steve. Great photos, too. One thing I'll mention, and can't offer any first hand knowledge, but for whatever reason Luxman understates the power on these (or at least the L-590) and pretends that they're solely class A.  From tests I've seen, the L-590 actually puts out around 90W/channel @ 8ohms, contrary to the claimed 30W, presumably switching to AB at some point. I assume the L-550 is no different.
Luxman also makes an excellent all tube Integrated amp. The LX-380. Has the same retro Marantz 7 look. The built in phono is also all tube and very good. I purchased the CL38U-SE all tube preamp about 7 months ago. Best tube preamp I've ever owned.
