You might check out my setup in my primary “Virtual System”. After having high powered Krell, Bryston, McIntosh etc with my 3.6s, I’ve been very happy with Audio Research tubes on amp and preamp.
I started with VSi60 integrated amp with KT 120s, then Ref 110, Ref 75, Ref 150 and now Ref 250 mono amps. Each amp had classic ARC sound with huge soundstage (tall, wide and deep), separation with precise imaging and I think you’d be surprised at how well the VSi60 Watt integrated amp drives the big Thiels in spite of most recommending high powered solid state amps.
