Another speaker you might consider if your space and dealer availability allows, is the Stirling Broadcast SB-88. It's larger than the other speakers you're considering but that will result in more life-like scale. It uses the same midwoofer driver tech found in the LS6, and like other Grahams, was also designed by Derek Hughes.
I have a pair of SB-88s and Spendor SP2/3R2s. The Spendors play with larger scale and greater bass depth but the SB-88s have the upper hand in refinement and fatigue factor. The SB-88s are also a bit more dynamic in the midbass. However, the new Classic series is alleged to be much improved in terms of dynamics.
If you're in the U.S. and interested in the Stirlings, send me a PM. I know where new pairs can be had for a great price.
