Hi Jriggy,
A few years back a dealer in The Netherlands ( AudioLife ) has organised an Accuphase vs. Luxmann show. Unfortunately, I could not go. You might want to call them. They are very friendly and if you explain them the situation they might be willing to share with you a thing or two (English is not a problem for them).
Also, have you seen the review below?
Luxmann L-590ax
I am an Accuphase guy, however, the few times I have listen Luxman electronics I have liked them very much. IMO both companies make very very good products and neither can be considered as being totally superior. Accuphase is more expensive and IMO has a more classier look and it is a bit more flexible (e.g. you can add a DAC to it and it also has a numeric indicator for the volume control). The Luxman looks a bit funny IMO, it has eyes, ears and teeth. :) However, overall, the Luxman probably offers a better bang for the buck as it is significantly cheaper.
Buying the Accuphase without being able to try it in your system might be a mistake as you might end up paying more for something that will give you less. At this level system synergy and personal preference are very important.
Also, be aware that Accuphase has introduce the E-600 class A integrated, i.e. the evolution of E-560 (which will be discontinued). Thus, you should be able to get a significant discount for the E-560.
Finally, be warn that these Japanese boxes are very addictive. Once you have one in your system you will want more! :)
Keep us posted.
