As a B&K dealer, I have been researching this since the Ref30 came out. After speaking to B&K several times, I would venture that a Ref 10/20 will be upgradeable to Ref 30 standards EXCEPT for the component switching and the new DACs. You will get the THX and the EX, and the new (and very cool) setup/processing software, which includes some room correction and far better bass management. They have been very tight lipped about the price so far, and availability should be(as earlier stated) sometime shortly after the new year arrives.
B&K Reference 10/20 Upgrades
I bought this in part for future upgadability. I have the REF 10. Has ANYONE even looked into upgrading 10. I just want to know waht, if anything, is available and a good contact. B&K apparartly doesn't respect email. Any experience helpful. Many Thanks from Ed. Happy hoidays. PLEASE !!!
