I have to agree with you they had a very engaging room. My favorite thing to do at this event is to walk into each room for a short snippet of listen and figure out which room I want to go back and hear.
I went back to Endows Audio's 7.2 room three times. I always go back to the rooms that sound good to relaxe and listen. I also went to their other room with the floor standing speaker but it was not a match for that room, I'm sure they worked hard to get the room to sound right, especially if they set up the 7.2 room.
I was impressed with the direction they are taking, you were able to get a very nice sound without sitting in the sweet spot.
Hope they come back next year.
