I've heard both in various incarnations. I'd definitely go with the Odyssey even though the Monarchy is a Class A electronic design. I find the Monarchy too layed-back. I had auditioned the mono's with 4 types of speaker's. (Small Totems, JM Lab 6.1's, small Meadowlark's, and, I forget).
On the otherhand, I was taken aback the first time I heard the Odyssey (prototype). Great control and depth. Upon hearing the production models, I think they've left the competition in the dust. Maybe 4 or 5 classic amps in that price range to compare to but not worth the search.
