I received my PMG last Tuesday and gave it a listen straight out of the box. I'll spare you the adjectives, only to say it was nice and very different than the BHK. I played a CD in an infinite loop through it for the next 5 days and it improved greatly. This thing is one fast, punchy preamp and surprisingly, has more dynamics than the BHK. Listening to Tower of Power live practically blew my hair back. Imaging increased dramatically as well as space around individual instruments and micro details. Suffice to say that it is extremely revealing and can make bad recordings sound REALLY bad. As much as I love the improvement over the BHK, is it a $6600 improvement? I guess it's the old audio conundrum, where we pay big bucks for incremental improvements. Disregarding price, though, it's a tremendous sounding preamp.
