Spendor D7 vs. Spendor A7

I have not listened to the A7. But I checked the Spendor site and the A7 and D7 are completely different configurations. If anything, the D7 are higher configuration models and if you have the budget and space, I would highly recommend the D7, based on the couple of tims I got to listen to them. Good luck.

I own the Spendor D9s and have spent time with the A7s.  I am going to assume the D7s are closer to the D9s than the A7s.  The A7s are fun speakers with surprising bass extension but lack the clarity in the highs that the “D” series supplies.  Very different levels of performance.  

The Spendors are checking a lot of boxes as I contemplate a new speaker purchase in 2019.  I plan to audition quite a few.  My question for this thread is what others thoughts would be between the D7 and D9 for use in a 20x15 room with 9.5 ft ceilings.  Which are better suited, all things being equal (which I know they never are)?  Standing at only 34 inches tall, the D7s seem a little small but I understand they project a large soundstage.
