Pass Labs int 60 vs. Luxman 590 uX ii

Do your own research. Lots of good options.
HiFinews magazine did a review of the Cambridge Audio Edge A ($6k msrp) and declared it to be about as good as a Hegel H590, at double the cost of the Edge A. Reprint of review here:

Were it me, I’d go Luxman, especially if pairing with Focal.

Since your speakers are pretty efficient you probably could use a lower powered class A amp.  The luxman and pass labs are both excellent choices.  It seems that a class A or strong bias in class A to A/B would be a good way to go with the focals.  Mike at Suncoast Audio carries both and he is a really good source of information (no affiliation with him).

I would look at the Naim Audio Super Nait 3 integrated. Naim and Focal are part of the same company. My dealer sells both Naim and Focal and they make an excellent pairing.

The Luxman L-590 isn't low powered. The 30watts is presumably the Class A rating, the amp will produce 90watts/channel into 8 ohms, according to a couple of reviews where it was actually measured. Nearly doubles that into 4 ohms.
