Bryston is a chip based software upgrade. I upgraded my SP1.7, it was $50.00 and included two chips, a chip tool, and all new case screws. It was easy.
The SP1.7 is devoid of bells and whistles, really straight forward, and downright easy to use. No video switching though!
I think the only difference between the two is the 5.1 input. I dont know about the SP1 and DPLII. I like it(DPLII) and wouldnt want to do without it, or DTS:Neo 6, for that matter. You better check with Bryston to see if those are available through chip upgrades in the SP1.
