They probably won't be at the show. I can't remember hearing about Transcendent doing a show in the past and they've never been to the Tulsa/Dallas gathering.Even if Transcendent won't be at the Lone Star Fest you'd have a great time and learn a lot if you went there. There are always some excellent sounding rooms and the folks at the show are just plain nice.
If you are near the Philly area I'd be happy to setup some sort of listening night. You'd have to put up with all the other audio loonies in the area ... but it makes for an entertaining evening.
