Have you tried the 771 bi-amp or the 1224 yet?
These were the original units for the 9846.
I have both units and they are AWSOME on these speakers.
I tried other setups including Crown VFX-2A with Crown amps and Altec amps. They could not beat the Hi-Fi accuracy of those little biamps.
I have a pair of the 9846B's and a pair of the Santiago's.
They are a much better sounding speaker with the biamping than just going thru the N501-8A.
Look for a pair, preferably the 1224's.
You will not be disappointed.
