I run my ProAc 140 Studios, bi-amp from four VAS mono blocks tubes amps (50/25 watts). I also run the 140 center channel from a Cayin A77 (45watts), one channel for the top and the other for the bottom. The 140's are rated 91 db sensitive, with the sides in 8 ohm, the center at 4 ohm. Room is small, 12x13, so I do not need a lot of power.
Sound is great.
I don't know how low on the watts, ultralinear/triode) you could go. I run all amps in ultralinerar mode.
Sound is much better on tubes. I was running six vintage monoblock Marantz m5's, which run in Class A, 25 watts.
Tubes have a 'softer' sound.
