I e-mailed Bryston regarding the upgrade and was told that it will be fairly extensive including new cosmetics and circuitry. the upgrade cost from the SP 1.7 is said to be about $1,800 while I was told that there will be a 5% price increase over the Sp 1.7 on the new unit.
I believe there is now a write up on the upgrade on the Bryston web site.
