I think Teac/Esoteric has been very unfair with use of their transports. They basically have a monopoly on high-end transports, and will not allow others to purchase under reasonable circumstances. At least, this is what I heard, and what the availability seems to suggest.
Personally, I don't like that Esoteric is always introducing some new version. Very confusing, and must not be good for resale.
For me, the only player beside the Wadia to consider would probably be the Scarlatti. Unfortunately, I've not had the experience. However, I'm sure it is wonderful, and probably leaves nothing to be desired when properly and fully implemented. I've been a long Wadia fan, so the 9 series was a no-brainer from my situation.
