This is great news James.  Not sure if you remember, but I sent Stereophile an email a while back asking about a review of the new 4B-SST.  I sent you this email also, and then sent you their reply.  I thought it was odd that they seemed to have overlooked the fact that the best selling "high-end" amp was completely redesigned.  They thanked me for the info and said they would look into it. 
Now I just have to remember to go out and get that issue, as the current October one is the last of my subscription.
