I owned an early version of the SJ202a, hand wired before the PCB went in'em. Ok little amp, pretty, nice external build, and biasing can be fun for someone just learning about amps, but its tubes and marketing hype, and not worth the money. Alot spent just making it look pretty like most tube gear. Granted alot of tube amps may actually sound nicer than many solid-state designs, for various reasons, but solid-state does it better and for less when well engineered. The jolida was an improvement from my H/K unit (I sold my NAD earlier so never heard the two at the same time) but for the money of one of the jolida's, there is better. Try these sealelectronics.com
