I have my 2.8’s next to my acoustat 2+2’s which are driven by a 100w Jolida tube amp.
I have my 2.8’s connected with silver played 10g wire I got cheap from a surplus store and frankly, at the volume I listen at, it’s massive overkill .
But hey, overkill is good! These amps are huge but honestly , I think three 100w amps triamped would be very good too.
Just keep them the same brand /model or you’ll be constantly fiddling with them.
