Pass Labs int 60 vs. Luxman 590 uX ii

I don't know the Aesthetx, but the Focals tend to be very airy but also "revealing." Maybe TOO bright. 

They are also challenging in the mid-bass due to low output impedance they tend to put there. 

This is really going to depend on your listening style.  If you like full range music, the Luxman.  If you like low level listening, something that's going to sound better turned down, the Pass.

Also, due to the low impedance, you may be better served by the Luxman 509 thanks to the robust output stage.  I could be wrong here, but I think it has more output transistors.... I'd have to do more research to find out.

In any event, I strongly encourage you to listen.  You may find your tastes are the opposite of mine.

Thanks for your perspective and observations. I'll study the 509...Unfortunately, this move will be based on reviews and opinions. I have no convenient means of actually listening to these amps...

Are these the only two you are looking into? If not, look at the Hegel H390 or H590. I was looking at Pass, Luxman and a few others, but like you, I was unable to audition the Pass and Luxman, but could the Hegel. Never looked back... 

i am also a big hegel fan... i think they sound absolutely wonderful, not a hint of ss glare or hardness, deep dark background, spacious wide and deep sound stage, tremendous bass control

other top ss integrateds - by pass, luxman, naim, ayre, belles are all in the same (top) class of sq, but i have come to prefer hegels

i also agree that the focal be tweeter is very good, but can be easily teased into brightness, so smooooooth is the key word on source and amp selection, in which case, one must also not rule out good tube amps, i.e. from stalwarts arc and cj, and respected newcomers like rogue, primaluna etc etc
