I thought about the DV-50 as well, but after several calls to TEAC I can't get a straight answer about future service and support. One time they say Esoteric is being reintroduced to the US market, then whien I ask who the dealers will be they call back and left a message saying there were no plans to sell them in the US. I love some of TEACs gear and the DV-50 looks like the best thing currently made, but I'm not going to spend $5K and not have a repairable transport.
I've got a Pioneer Elite DV-47Ai home for audition this weekend and so far I really like what I hear. It's not the DV-50 in terms of quality of build, but as Eldartford said, it's a good unit (similar to the one he recommended, but newer) for the $800 the dealer said it will be if I keep it and I can wait to shell out several K until the format wars settle out.
