Integrated SS amps - Luxman vs. Simaudio Moon?

Instead of separates, I am considering a high quality integrated amp for my new system. The speakers I am considering (Verity Audio) are not hard to drive. The two brands at the top of my list are:

Simaudio Moon Evolution i-7 (or the new 700i) vs.

Luxman L-509u (or L-590Aii 30 wpc pure class A).

I have heard theses units in different systems at different dealers, and so not direct comparisons.

Any thoughts or suggestions?

Regards,

Mark
