I couldn't wait for the local launch of the DC-37 and ordered mine from a contact in Japan. It arrived yesterday and here it is .
It does sound a lot like the DP-720 so no surprises there. At the moment I have it hooked up to my DP-700 via HS-link. The results are superb and I can't wait for it to be fully run in. I have no idea how long that will take but it's running 24/7 in the meantime.
