Spendor D7 vs. Spendor A7

@mushka,
The D7 would be better suited to your room. You will be thoroughly disappointed with the D9 in a 13X11 room. If you can "pull" the D7s in the room, say about 36" from back wall and 18"-24" from side walls, you should have amazing music.
Like @drrsutliff mentioned, the D9 will either overwhelm the room, or the bass waves will cancel out and kill your musicality.

I had home audition of the A7s and D9s. I purchased the A7s for my 15'x24'x8' room. To my ears, the A7s just sounded more musical. I preferred high frequency and imaging of the A7s. I had the coin and space for the D9s, but just preferred the A7s. This confirmed my findings at the Tampa Audion Show in February. Low end is impressive on these, but I have order a pair of REL S/3s to compliment these wonderful mains.

So far I've tried D7, A4, A6R, and have an A7 on the way, being shipped tomorrow. 

I've run them mainly with an exposure 3010s2D and now with a Hegel h190

I didn't like the D7. I found it accurate but harsh especially on the upper end. And there was no love coming out of these speakers. Not for me.

The A4 however is a delight. It's just a loving speaker. It's inviting and warm and musical.

That's how I describe the A4

Tried the A6R after the 4 and found it airy. Not much of that inviting warmth of the A4.

 The D7  for me is scientific. the A6R  was like watching a well recorded show where you can drink cocktails in the back and chat.   The A4 just stopped everything for me. Intimately demanding my attention. With a great musical composition.

I find the D7 To be like those high DEF TVs that are 120 Hz and everything just looks overly precise.

So now I’m waiting for the A7 and I’ll keep you posted.  I think spendor are onto something very special with the new A line. 

I auditioned and listened extensively to A2, A4. A7, and D7 at dealer with Audio Research amps and Rega amps and Ayre amps.
I loved the A2 and A4 at their price points. They really sound fantastic and musical.
Initially I went into my extensive speaker search journey (20-25 speakers auditioned for extended periods over several months) with a $5k speaker budget. I was liking the A7s and leaning that way.
Then I heard the D7s and I knew I had to have them. I had spent an hour listening to the A7, and then went straight to D7 audition. WOW. The sound was on a completely different level - so much more refined to my ears. I had read all the mag reviews saying Spendor was such a laid back speaker (some said almost boring) but this D7 sounded anything but laid back. The highs were perfect and for me it just checked every box. I pair them with ARC and MIT cables and I am very happy.
My second system has Spendor SA1s. 

Other speaker brands that sounded good to my ears during extended listening sessions during my quest were Dynaudio, Sonus Faber, and Vandersteen. 
But nothing beat the Spendor D7’s for my ears

@greenapple

the D7s need a lengthy break in.  I owned them and found them to sound as you describe for the first 200 hours or so.  After 4 months they sounded spectacular.
