Grimance,
The Jolida 1501RC is hybrid amp, by that the preamp has the tubes, a couple of 12AX7s, and the amp itself is a 100 watt solid state. Sort of the best of both worlds. If I didn't already have Jolida tube integrated (SJ-502A), I would probably have one of Jolida's hybrid amps. You ought to drop by the Jolida site and read up on it, btw here's a link -

or better yet, find a nearby Jolida dealer and have a listen. Definely a step-up from the Rotel, and with the 12AX7 tubes, you don't have to worry about biasing the amp.
