Power Amp recommendations


My Rotel RB-1080 power amp has been having problems losing the right channel- it's been fixed, but the guy told me he'd discovered it's a known problem with several models of Rotel.

I'm thinking about looking to replace the amp, though I've enjoyed it quite a lot, and am looking for suggestions. Over the past year or two, I've returned to listening to LPs almost exclusively, and have built a pretty nice selection of audiophile quality 180/200 gram LPs, including quite a few MOFI titles.

My present set-up is as follows:
Music Hall 5.1 se turntable
Denon DVD 3910
Marantz bd 5004
Marantz 7001 pre-amp
Rotel RB-1080 power amp
Revel F12 speakers

What should I be looking at to replace the Rotel? Is there a reasonably affordable way to get into tube amps, if I were so inclined, and should I even consider them?

Minorl makes a good point. If you have any local dealers, I would see what they have to offer. I lot of people complain about dealers, but most of the ones I know, are more than willing to bring equipment out to a customers house and set it up for a demo. If not that, they'll almost always let you "buy" a unit on display and keep it for a couple of days.
Thanks for your comments and sorry for the late response- I sort of lost touch with this thread. The Rotel has been fixed and is working- when I initially posted the question, I hadn't received back it, yet. My repair guy had told me, though, that if the problem happens again- and this was my third round of repair- that I'd need to return it to the manufacturer, so I posted my question about replacement. I'm a far cry from an "amp of the month" sort- I used the components I bought in 1982 up until the past few years, when I've upgraded piece by piece from a Luxman receiver, KEF speakers, and Denon turntable. Earlier this year, I replaced the Denon, which was the plast piece left unreplaced, with the Music Hall. At any rate, I began to consider the possibility of replacing my Rotel.

As of this writing, the Rotel is staying, but in the process, I did decide to upgrade the Marantz P7001 to a Parasound Halo P5. That should do me for quite a long time, if not for good. Unfortunately, though, I have no way of auditioning equipment- there are no dealers of quality equipment within a couple of hundred miles of me. I was having the same discussion with my service guy- it's unfortunate there is no efficient way to audition equipment anymore. I do have high expectations that I'll be very happy with the Parasound, though.
