Not in any real order but- 
Justin's BHSE 
Tyll's HD800 with whatever I can hook them up to 
 
Whatever Craig brings, he never disappoints and always make me want his newest iteration 
 
Frank's newest creation, always very impressive, 
 
Blubliss' rig, I always enjoy the short time with them but this time I will be a little more selfish 
The Smyth-Research system, it is just so impressive everyone needs to audition this system----but after I have had my turn  
 
The Woo Audio latest, because I do not believe I have had any time with any of his amps so far 
 
Lastly, the Audio gd amps and dacs 
 
These are the first round but there are a number of small boutique builders and gear vendors attending with some really interesting gear worth checking out.
