Bryston's BP-26 vs 17 cubed

I tried this post once before without much success. Here it is again. Does anyone have any first hand (or ear) listening experience with Bryston’s BP-26 and the BP-17 cubed? Any other comparisons will not be helpful... My gear consists of the following:
Joseph Audio Pearl 20/20 Graphene. Classe’ CAM-600 Monoblocks. PS Audio DirectStream Dac and Memory Player. BP-17 cubed being demoed now.
Cardas Clear Reflection speaker Cables. All dedicated circuits/with Furutech Receptacles. Furutech Power Cables....
