The S.E.X. amp will be a little quieter thanks to the DC heaters. The Stereomour will bring you DHT magic with a little extra power providing you stick with the 2A3 outputs. The way I look at at it you cant go wrong either way. That said, if your budget allows get the Stereomour. Better yet, get both. I always keep a S.E.X. amp on hand to run my main system when I'm tweaking my pre amp and monoblocks.
