This is for Georgehifi especially but others can chime in.

I would be looking at something like Bel Canto ref600m amps for top notch sound, bang for the buck, manageable size, and low power consumption/electric bills.

I say that based on my current use (for several happy years now) of older ref1000m amps with other Dynaudio monitors (Contour 1.3mkII).

I also have newer current generation Bel Canto c5i 60w/ch integrated amp in my second system and with the Dynaudio monitors the only thing more I might want is more of the same quality watts.

Hard to go wrong with Bel Canto products in general, IMHO. They do things right! Like Mr. Pass but somewhat differently and perhaps a tad more focus on affordability.

Surprisingly a Schiit Vidar

The Vidar would be a good choice also for much less money, but the OP specified only two amp to choose from the Pass Labs and the Devialet.

Cheers George

looks like someone told the truth so the mods removed his post

Actually, it was @onhwy61  post and mine directly after that was removed. And yes, there was nothing but truth stated. Keep in mind it was just opinion anyway.

I believe (not sure and could be mistaken) the reason the posts were removed had something to do with an erroneous determination on audiogon's part (likely programmatic with non-human intervention) that the posts were spam related. 

@georgehifi I am open to any suggestions. I have a dealer who sells and loves Pass Labs. Frankly it’s one brand I can’t remember anyone badmouthing at all. @mapman I have owned a Bel Canto Preamp and liked it a lot. The Ref 600 intrigues me and my dealer sells them  so maybe I can demo them also.
