Hi Jeff
I am working on the manual now - is there a particular spec your interested in?
James
Not so much interested in specs (I take it for granted they will be good or you would not release it 

) as I am the features.   
From the latest pictures of the back there have been some changes in the number and type of inputs and outputs, I was looking for a list of what they are.  
It looks like there are 10 balanced outputs, are there multiple sub outputs?  
Given Bryston's track record I am assuming it will be a excellent DAC.  Can the SP3 be used to integrate a pair of subs with the mains for 2 channel playback when the SP3 accepts a digital input?  
Also, waiting to hear how it sounds fed by the BDP.
