Well, the ref 200's are in the system now and I'm more than just a little impressed. The soundstage has expanded in every direction and instruments are better defined, almost as if they have more space to themselves. Contrary to previous experiences with lesser subs, the Ref 200's have brought more definition and air to the mids and highs, rather than the muddiness people have come to expect from subs.
Elducsesol, you've had success with alternate cabling? Are you using the Speakon connector? i found the differences between the speakon and the rca to be night and day.
i had some people over last night and all they could say was 'oh my, listen to that'. Nice endorsement!
