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.

I believe Boulder uses complimentary BJT (bi-polar) output transistors in their amps, these are far better for current delivery into low impedance, and better suited to low impedance and -phase angle EPDR load of the Sabrina than complimentary Mosfets (Pass) would be, I don’t know what the other amps use.

From 50hz to 200hz they have an nasty loading for amps to see, especially at 75hz.
