Probably one of the main reasons both rooms sounded significantly better this year than last year 
Tyson, I do agree that the new Bolder/ Daedalus speaker cables were one of the big improvements. also, in the Glaibier room (1130) his Ulysses were the standard XO last year and have since been upgraded to the AP crossover , huge improvement. also a big step up in both rooms as for power amps. in my room we ran the stock KWA 150 last year and this year had the SE upgraded version, again a huge improvement.
glad you liked the room more this year. if I do RMAF next year I'll try to dial it in using Tool!
thanks,
