It's been quite awhile since I last listened through a Canary, and haven't heard the Orchid & Canary juxtaposed for listening. Note also that Canary is substantially less expensive than Orchid, which I assume is largely due to the 1541 chip being scarcer and more expensive than the 1545. Canary has discrete transistors current>voltage conversion whereas Orchid has an opamp in that role.
My memory of the two is that Orchid is essentially a richer-toned Canary. I consider them about equally euphonic (as in forgiving, and "wrong" in a good way) but Orchid is more vivid and I think dynamically it has more slam.
