I have Dennis's PSE-300B amp and love it. I ordered on a whim to compare to my Coincident Frankenstein 300B monoblocks which have handily bested all comers over the last 7 years. Well, the PSE crushed the Frankies in most areas over the course of a 4 week A/B period. I ended up selling my long time Frankies and have not regretted for one minute since.
