The Traformatic Rhapsody 300B is absolutely not your pop’s or your grand pop’s 300B amplifier. It is a very much new and improved version with reach—frequency response—that other 300B’s fantasize about or, at the very least, dream about. It’s got bass, the proverbial 300B midrange, though there is an argument for it being even better than most 300Bs here, and it’s got good treble extension.
