Well, I might be able to help. I have among so much hardware owned Thule PA350B amp and Thule PR150 pre amp. Sold and bought Bryston, for one reason--If I want colour I will add it downstream. The OB1's will be REVEALING with your pre-amp/amp combination and you will either love them more-or less. In my more than humble opinion you will love them MORE. But the minor artifacts that (with my ears) heard with your very educated choice of amp and pre-amp will translate to MORE detail-AND you will no longer be searching for speakers. The OB1's are so neutral-once you accept the transmision line bass, that you can concentrate on your source. Go for the Jolida 100A, and its available mods or the AH! either way you are off to a great start.
