BHK Sig. 250 ?


Anyone hear the new BHK Signature amp from PS Audio ?
Bascom King has designed some well respected amplifers
for other companies, so this should be pretty special.
Your take ?

BHK 250 arrived a couple of days ago.  I am very satisfied with its performance.  No issues like the first one I had.  No regrets moving up from a Parasound A-21.  PS Audio has hit one out of the ballpark.
The BHK 250 is now on my list. A few used ones out there that makes the price more affordable. I would like to hear comparisons, if any, of the 250 to the Benchmark AHB2 amp. I know they are two entirely different breeds and price points. 
I was thinking it would be a great match for my RP-5 tube pre and Zu Speakers. I wish it had the ability to go "mono" so one could add another 250 in the future. I know the 300 are monos, however, they are quite expensive. I have seen used pairs around $8-9K
