Luxman L-550AX


I saw that there is a new release in the Japan and now US market of the integrated class A Luxman L-550.

Anyone knows whether, apart from the specs., is there any sonic difference between the old L-550AII and the new model L-550AX?.

Thanks.

Ah yes, I have tried the headphone out with Grado Rs1i's - great synergy). when the lights are low and I want to listen to some Miles and don't want to wake up my neighbors, its
a great solution. I don't see the volume control going up above 50% for any of my uses so far (about 3 weeks). Includes playing a low output moving coil cartridge as well (well that 's maybe a hair over 50 or 60% if I want to crank it.
In terms of heat, well there is some coming mainly out the top but really not too obnoxious.. I thought it would be hotter. I'd say you need a good 6 inches of free space around the top to be safe.
I have a new one on the way now. Bought it without ever hearing one. Very anxious for it to arrive. Also ordered a Sumiko Blackbird HO MC to use with it. I've heard very good things about it and it's phono stage.
