In the NYC area I recommend Wes Bender Studios  in Brooklyn.  He is very friendly puts together great sounding systems (both tube and solid state )  and has great speaker lines :    Marten ,  Hansen ,Gamut to name several . I know none of them were on  your list but they are all excellent.  Wondering what your budget was it makes it easier to recommend speakers in your price range.

Thanks nsp. Wes Bender Studio is on my list. The list of the Speakers/Models I have mentioned are the ones I like, of course from the reviews i have read here on Audiogon. I have never personally heard any one of them. And during my short trip to USA, I might not get to listen to some of them as most of them are discontinued.

Your inputs will be a great value to me. My price range is 3000-4500 USD and I might be able to stretch a bit more if I am getting very good value. That's the reason I am looking at Demo/Used pair. Any suggestions are most welcomed.

Just saw your last response . sorry for delayed response.  in your price range new speakers  which have been reviewed very favorably in Absolute  Sound are :Revel Performa 3F206,  Tannoy Revolution XT8F ,  Dynaudio Focus 260 . Keep in mind I nhave not  HEARD THESE speakers just reviews.
Wes Bender has a demo pair of Marten Form Floors which you can hear at his studio and I think also entry level speakers from Gamut. Wes was asking what electronics you use and cables and your room dimensions/? Here is link to see and hear the Martens:  Youtube.be/sD8WZvrcRDo  ..
A speaker which I have heard twice at length is Focal UtopIA Diablo , a  monitor speaker w/stands.  IT is really terrific and gives you a real taste of the high end. It might be out of your price range as it ratails for I think 13-16k and used is about 8500-9000.

Thanks.. My room dimensions are 12 Ft x 22 Ft , height part 7 Ft, Part 16 Ft, with natural stone flooring and Masonry walls. SO very live room conditions. (However Im planning some cloth curtains and room treatments for that. I have an old Cary Preamp (CAD 5500). But I have finalised a new preamp (Cary SLP 98 L) and digital player is Sony HAP Z1 ES. My interconnects are Morrow Audio MA 1.1 (RCA). I'll pass on this information to Wes Bender also. 

I'll also put Focals on my list. Some good reviews on them with Pass amps. Not the Utopia Diablo though, they are way out of my buget.

I just saw another current thread on Silverline Sonatina MK IV. A current silverline model and within my range. I tried to find some feedback on that on audiogon but there was'nt much written on this model. However, i'm very encouraged by the positive feedback from the Sonatina MK IV owner, laurendy3.
