I'm looking to upgrade my setup sometime soon and was curious if anyone had compared the two lines while auditioning? I'm particularly interested in Def Tech's bipolar design and would ultimately like something with a great soundstage that really envelopes me in sound. Being that this is an Ascend forum, I know that most of the responses, if not at all will recommend the Ascends, but I'd still like to know how well they stack up against each other. Any help would be appreciated.
