Ryllau, I've got a Marsh 400 and I love it. I can't speak to the Odyssey, although it sounds like a good deal. But, I do love the transparency and neutrality of the Marsh. I'd stack it up against some very expensive gear - I have, and it sounded great. I haven't listened to an amp for under $5,000 that I'd prefer, and it took me two years of listening before I bought the Marsh - I nearly lost my girl friend in the pursuit!
