huh...the thread got locked over on HF i guess cause everyone was posting impressions in the meet organization thread 
 
at the meet, 2 people commented on one of the BHSEs having a potential issue.  mypasswordis was one of them, claiming the channels had been reversed.  Well not quite, but i did discover the left channel was out of phase thanks to the assembly people swapping 2 wires on the input boards *just fixed it* 
 
one more thing i have to always check twice now...
