guys, i'm not too sure you need an impedance converter(maybe yes for sony's). i got the presto II's and the only connections are xlr and nice locking rca. no transformer is evident. i run the aes 2 into my dap1 and send the aes 1 elsewhere. never had a problem. i need to call nutter today on a different matter and will ask him.

Yeah, I've been running straight AES/XLR > RCA/coax without an impedance transformer and have encountered zero problems. But I think I'm gonna do it anyway just for kicks. Let us know what you find out.
