Sorry for the late response to all, I just got home from my extended vacation in the Twin Cities.
Thanks Luke for hosting! And Dustin for helping with the coordinating! I had a lot of fun and hope to make it to other gatherings in the future. It was also great visiting with all that were able to attend. I had a lot of questions answered and learned a lot from many of you.
Couple of items to note. We didn't run a ton of different set-ups, nor did we spend time doing any A/B comparisons. This was a session mainly to listen to 2 separate set-ups (Full Range 215RT's vs U215's w/ insane subs). The room was not treated, nor was the system EQ'ed. The room did not lack bass in any 1 seat, although the hot seats were along the rear wall, but more so in the rear left. Although the front row was not the hot seat, the couch had a lot of tactile movement, even sitting on carpet over concrete. The ceiling is still unfinished, I think if there were any sources of noise, the 1 or 2 spots were identified and Luke is on it to secure before the ceiling goes up. I was very impressed with the work he had done to tape up and secure the light cans and HVAC from shaking. There was no unwanted noise whatsoever that I recall, unless running the Pulse scene at reference on either set up. It is amazing on how far Luke's place has come since I last visited Jan '13. He was running his 4 sealed LMS Ultra 18's at that time, and I recall thinking, nothing can get better than this. He has since moved his theater into the adjacent space that is shaping up well. Carpet was installed just before we got there. One really cool feature that Luke had done to his rack was the XLR patch panel that he had soldered connections to from his minidsp. Switching out the speakers was just a matter of seconds, if you don't count the actually heavy lifting part of those 215HT's.
The JTR's were already hooked up and playing when I got there shortly after 10am, and Luke was starting off with some music. Like others have said, I was convinced that the subs were running till Luke told me otherwise. We spent a bit of time running through various clips and Luke was open to any and all requests. It wasn't long before I opted for ear plugs, as I could tell that we were really going to be giving these setups a good workout. I have read from many postings on how impactful the Pulse scene is, as well as the Open Range gun fight scene, which were my favorite 2 clips that were played during the session. Specifically, the Pulse scene definitely pulsed inside the room. I had ear plugs in, but my whole body was pulsing with the JTR's, it was really amazing. Another fun clip was a drum solo from a Cream Blu-Ray that provided plenty of room shaking bass that was replayed for those that came later. I will agree with others, no sub is needed if you own these JTR's. I own T8HT-LP's and am a big fan, so I was very excited to hear these mains. I helped Jeff carry these 2 speakers out of the listening room so that the York's could be hooked up. These things are heavy! I was not on the crew that carried them up the stairs, but at least they had 4 guys per speaker.
Yorkville U215 w/ dual ghallarhorns & dual othorns:
I can not give direct feedback on the York's vs JTR's, Luke's subs are just plain ridiculous! The Yorks had the aid of the subs, while the JTR's ran full-range. Any and all that belong to AVS would envy this if they ever had a chance to hear this Yorkville set up with his wall of subs. Weird thing, I thought that the subs were the wall at first - the room is darkened and the tv and speakers were in front of the wall of subs, and they take up roughly 3' from the front wall (not small..). You could definitely feel a lot more bass with these subs running. The same Pulse server room made you feel nauseous, absolutely insane that speakers/subs can do this to you. The Yorks in the higher frequencies were very clear and full, just as the JTR's. I can't get very scientific in describing them, all I can say is that they sounded amazing. Neither set up are your "normal" person's set up. But, I don't think any of us are "normal".
I am again thinking, over 1 year later from my first visit to Luke's, how can you get better than this.. Can't wait till I can attend another GTG!
