Rich, I guess it's just GTAW & SI this year, anyway I meant you'll hear the room and be able to make some comparisons. Steve is bringing an Esoteric K01x SACD player & Acoustic Signature TT as sources. With many similarities between the 2 speaker systems, I'm interested to see how the GTAW full range driver and tweeter compare to your planar mids with the same/similar GTAW tweeters, the OB woofers appear to be very similar. I'm looking forward to seeing you again in Rockville, will you be at RMAF?
