Need feedback on loudspeakers


Hello All,
I have been researching a lot about loudspeakers lately - their measurements including sensitivity, impedance, phase, etc to make sure that they match in my system. Also had a chance to listen to a couple, but yet undecided, since I am not able to listen to all of the ones I have shortlisted below. I have a very short list of criteria for the speakers:

Sensitivity more than 88db
Nominal impedance 8 ohms and minimum not dipping below 3.5 ohms
Go down to about 27-30Hz
Price range is about $7k new/used

The loudspeakers that I have short listed are:
Spendor D7
PSB Imagine T3
ProAc D30
PMC Twenty 24
Tannoy Definition DC10T
Revel F208
Focal 1038 (used)

Could also consider the following, but not sure if they would match in my system because of their nominal 4 ohms impedance:
Sonus Faber Olympica III (used)
ProAc D40R (used)
Audio Physic Scorpio 25 (used)
PMC Twenty 26 (used, but has low sensitivity)

I love speakers that have the sound image starting about 2-3 feet behind the speaker front face, throw a wide image and disappear completely. That is what my current speakers do. My room is 15 X 18 X 8 and the speakers are placed very precisely (5feet from back wall and 3 feet from side walls) to achieve this imaging. I have a few panels to tame the sound in the room. My amp is Parasound A21 and I have an excellent Promitheus TVC. Current sources are able to effectively drive the amp and the speakers, without any issues.
I have listened to PSB Imagine T3 and Audio Physic Classic 20, and found that they image per my liking.
I know I have listed too many speakers. But would love to hear from owners of these brands on the "vocal characteristic" of the loudspeakers, now that I have provided a brief explanation of my preferences. There is no denying that the best way to seek a set of speakers is to audition in person. But sometimes this is not possible. Please provide your feedback, as much as you can. Thank You in advance!

@milpai .....thanks much for the cable advice.  I've read a lot about Clear Day cables and am quite curious.  In your size room, I'd probably try and stretch for the Proac d30r.  They have tighter and better quality bass than the 20r.  The Tannoys are very good though and seem to be at home playing a wider range of music types.  If I listened to mostly vocal and small jazz groups like I used to, the Proacs would be my choice.  Nowadays I mix it up more with various genres and the Tannoys seem to respond better as they're more dynamic.  Tough call really.  Regards......

Thanks for letting me know soix :-)

dave_b,
Last year I auditioned PSB Imagin3 T3 and the Totem Forest Sigs in DC area at the same dealer. I felt it was a unfair contest, since the PSBs were hooked up to the new NAD separates (M series) while the Totems were hooked to some high end McIntosh. The rep was pushing me towards the Totems, when I actually went in to hear the PSBs. That sort of put me off on the Totems. Nevertheless the Totems sounded pretty nice. One thing I did find - you need to really "up" that volume on the amp to get the Totems to sound up to their full potentials. At lower volumes they loose their charm.

carmenc,
You are welcome. Hope you have the same positive experience that I have with Clear Day. As far as I can recall the demo of the Tannoys I had last year at AXPONA, I can very well understand what you mean by the "dynamic" sound of the Tannoys. If I were to guess what you mean, I think they are more upfront than the ProAc - is that right? Looks like I have to do a bit of traveling this summer to listen to a few speakers. One more loudspeakers that impressed me was the LeHave floorstanding model at AXPONA. But it is beyond my budget.
The Magnepan 3.7i is very good. I bet the combo of an A21 and the 1.7i would sound sweet indeed. I have the MMG's and have heard the 3.7. I was astonished by the sound from a good amp.
FYI, Totems are renowned for low level dynamics.  If they did not deliver low level excitement than they were not properly fed enough juice.  Macintosh is notoriously over rated and under powered!  Also, use MIT cables if you want to hear music and not just random emphasis in various frequency domains from wires with variable results.
2pysyop,
Thank You for the recommendation of the Magnepans. I am sure they would sound good in the right system. For my requirements, they are simply too large a speakers and they are slightly less efficient than what I am looking for.

dave_b,
Don't get me wrong; the Totems sounded pretty good. I will consider them again when I visit DC next month.
