Spendor D9 vs. PSB T3 speakers.

I can't say I've heard any PSB speakers but I have heard and love Spendor's many times. That is the direction I would head but it's your ears, are you able to audition either speaker?

I haven't heard the Spendor D9s, but I would expect them to be glorious.  I have, however, heard the PSB T3s.  They are a wonderful speaker and worth every penny.  I heard them with a Primaluna Dialogue integrated with stock tubes (so not much wattage, likely 35 watts).  I still have a memory of hearing certain guitar response motifs hang in the air.  I wish I could compare them with the Spendor product.  

There are seemingly no brick and mortar Spendor stores in the Chicago area.  I would jump at the chance to hear them if I could.

@jbhiller ,
Search for "Kyomi Audio Chicago". I heard the Spendor D7 there. Owner  George Vatchnadze was very nice and gracious even when I visited him twice to make a decision. BTW, between the Spendor and PSB, my vote goes to the Spendor because it is more musical. Have not heard the D9. But I think the D7 is same as ProAc D30R. I purchased the ProAc D48R for the scale and dynamic impact the bigger speaker makes. My guess is, the same goes with the D7 Vs D9.
Complements to PSB for making a super neutral loudspeaker - the T3.

I have not heard the D9 but have heard the PSB T3 and just recently purchased the Spendor D7.  
The PSB is a very nice speaker with a smooth presentation but the bass response can be overdone and peaky / one note hard sounding. 
The design if the Spendor tower's slotted port / semi transmission line lets them produce a very high quality bass that is unique and set apart from the competition.  Give them enough power and they will easily play full-range with authority with clean, well defined notes.  
In fact the bass response during my D7 demo is what sold me on them.  I played a jazz piece with a well recorder upright bass and could not believe the sound, powerful physical impact yet well defined and no peaks whatsoever.  I was sold instantly and am extremely happy with the purchase.
