I have not switched to odyssey, but rather added a pair of stratos monos to the krell ksa50s and arc vt130se stereo amps which I own. I rotate these amps among various loudspeakers. With the deep bass limited and slightly overdamped Merlin VSM SE, the krell and the arc both outperform the stratos, at least to my taste.
With the verity parsifal encore, I clearly prefer the odyssey to the arc and marginally prefer it to the krell. While it is the most obviously solid state sounding of the amps I own (most powerful deep bass response, leanest in the mid-bass, with very slight dryness through the treble) the stratos mates terrifically with the very slightly underdamped verity speakers. As usual, careful component matching is the key. More unusual, is the odyssey value proposition, which is awfully tough to beat, even if you're relatively price insensitive.
P.S. - I would direct you to the recent odyssey review in TAS, which I found unusual in that it very closely mirrors my own experience with the product (other than explicitly identifying the rather startling deep bass capability of the stratos, which - to be fair - may be unique to the monos and not applicable to the stereo unit under consideration in that review)
