Best amp for Wilson Sabrina


Hello friends.  Thinking about an amp for my Wilson Sabrinas and would like the thoughts of the collective.
I use BlueSound for the rest of the home (in ceiling, sound bars, etc) and would probably stream from a Node 2i when being lazy (and want the same tunes throughout the house) and directly from the amp/DAC/pre for serious listening serious I want to listen.

considering:
- Boulder 866
- Sim Audio 330 and 390
- Pass Int-250
- Goldman Telos Integrated

Thanks in advance your thoughts.

Check out the AVM Ovation A 8.3 integrated.  It has enough power to drive the Wilsons, has a wonderful feature set and a neutral to slightly warm sound profile that will compliment them beautifully.  

Full disclosure, I am an AVM dealer but that is more because I am a huge fan of the product line than anything else.  
highend666... I have the dag integrated with Yvettes. Can’t imagine anyone would be unhappy with this combo. The dag is extremely smooth with the best midrange I’ve yet heard whether tube or SS. Also the final version is quite beautiful imo. 
When I was searching for an amp I seriously considered Simaudio.  But when I looked at how close the speaker terminals are I was darn near terrified.  They are crazy close.  If one wanted to use bare wire, one little errant strand and POOF it would be a SimArc Welder.  Ended up with a Krell unit.  
I auditioned the Dag Progression integrated with Sabrina X's this weekend.

It was being used only as a power amp, with a DCS Bartok as the DAC/streamer.

It sounded fantastic, really brought the speakers to life over the McIntosh gear to my ears. Though I can't vouch for the fully integrated Dac on the Dag, nor am I fan of the looks (a little blingy/espresso machine for me), I'm positive it's a great pairing for the original Sabrinas.

I'd like to try them with the Moon gear as well, as they pushed some of the other reference speakers I tried really well.
