I have Frankensteins for close to two years now. They are everything that I had hoped for and more. Prior to buying,I had listened to and researched many tube based amps.After reading what people said about 300b`s on the internet, I was scared off because they were thought to be slow and lacking in bass. All I can say is that these amps are ANYTHING but slow and as dynamic (with the right speakers)as my ss Denon monos that I had before. Bass is tight and realistic.
Definitely worth seeking out to audition.
