Compare Ayre, LFD, Luxman integrateds?

Stereophile has Ayre, LFD, and Luxman integrateds at similar price points listed as "class A." How do they compare with each-other? I'm sure they are all fine products; I'm hoping to hear from people who have actual experience with at least two of them and can comment on their differences.
There have been tons of comparisons here already... All depends on what you're using them with...More, please..

If these amp are listed as class A there have been reviews on them in Stereophile. That would be a good starting point in your search....
So let's compare these amps. There's no info. directly comparing these amps, just little snippets about them all over the place. Has anyone compared the three brands?
