Pass Labs X-600's vs. XA-160's


I recently purchased a pair of Dali Euphonia MS5's. Sensitivity is 89db. I know these amps are of different power ratings and class, but does anybody have any experience with either or both of them. Which would be better suited for these speakers. I am also considering the Electrocompaniet Nemo monoblocks. I use a Pass X-1 pre-amp. I listen to classic rock, jazz, and classical music.

Percon, can you please elaborate on why you think I'd be happier with the 600's over the 160's. Is there anything specific that makes you feel this way? Being a dealer, you have the opportunity to listen to and evaluate both of these amps. Is there something you like better about the 600's?
Tpsonic, thank you for the TAS information , and perfect timing! I will go out today and pick up that issue. BTW, I would like to change the room color!
Zippyy,no recommendation on room color.From my experience,I don't recommend Manley/VTL.I'm sure there are plenty of happy customers,but you seldom hear of the people who have had to fight with these amps in one form or another.Most have moved on to other amps.Just my opinion,take it for what it's worth.
Tpsonic, Perhaps a misunderstanding. The Nemos are manufactured by Electrocompaniet. Unless there's something I don't know, what does Manley and VTL have to do with it? Those are both tube amps and the Nemo's are Solid State. Can you please clairify ? Thanks
Forgive me,the Nemo brought to mind the Neo Classics.With the price of the 600s here on AGon.They might not be a bad choice.I have also seen the Lamm M1.1s fairly cheap.The 600s are balanced only,does that affect your choice?The 160s offer both,I believe.The 600s prefer a slightly warmer midbass and high frequency character upstream of them.Maybe a tube pre???Non silver ICs??
