I have a pair of Ming Da 3008a monoblocks. 40 watts of SET. They play as loud as a 100 watt SS amp. I never forgot when I first heard them.....how the music stopped and started on a dime with the best separation and black background. It was a quick education on cross over distortion. If the Benchmark amp could achieve this, with say a tubed CD player, I would be interested. On the other hand it seams as if the amp is at its greatest when paired with the DAC.
