To compair tube amps with the Marsh isn't really fair, and brings up the tube vs. SS debate once again. In spite of the common notion that an amp should sound warm, smooth, or liquid, the fact is, that a good power amp should have no sound at all. It should merely take a 2V signal, and boost it to 30V or so; that's it. There are those that will say that if an amp adds any smoothness or anything else, then I'm sorry, it's a peice of crap. Some people like the colorations that tubes add, and that's fine. I have nothing against tubes, and in fact plan to run my Marsh A400 through a Blue Circle BC21 tube preamp when it arrives next week. My decision to purchace the Marsh was largely based on the recent TAS review. I don't mind mail order, as long as I have the option to return it if not satisfied. I don't like to limit my options to only what's available locally, and neither should you. The Odyssey amps have been getting great feedback, and are definately worth consideration. I think either one will offer superb sound at a great price, but I would try the Marsh first.
