The D7.2 are not too big for your room, I had the D7 for a while in a similar room and they sounded fantastic.
I used a Rogue Audio Cronus Magnum II tube integrated and would greatly recommend using a high powered tube amp with the Spendors. The Spendor speakers are fast and lively and need some tube refinement for best sound.
The 100 WPC Cronus Magnum drove them with power and dynamics and never ran out of steam. Rogue has since released the CM III integrated.
