Which Speaker in the 4-6K Range?


I am interested in buying a pair of full range floor standing speakers that have the following attributes:(1)Sensitivity of 90db or greater. (2)Bass extension down to at least 25-30hz. (3) Solid built quality. (4) Ability to simply diappear and (5) cost about 4-6k. I am considering the Silverline audio Sonata and Coincident Technologies. I prefer the Hales Design Group Trancendence 8 but it costs 10k unfortunately. Please help.

Dekay, your comparison with Quads and Maggies is interesting. How did the Sonatas sound in terms of transparency, imaging and soundstage? I admit that I'm hooked on transparency and detail but my electrostatics compromise the low end, which bothers me once in a while.
I should have mentioned that when comparing the Super Eclipses (which come without a grill), you should remove the grills from the Sonatas. They sound much better that way!
Hi Jim: I should have said in the "same league as" in regard to sound reproduction, as the Quads sound different from the Magnapans. The Sonata's had a great deal of detail and a very wide and deep sound stage. They were less bright than Magnapans, but without loss of detail (kind of like the Quads in this respect). They were more dynamic than either of the planers (a plus IMO), had a full and very well integrated low end (in this room) and a rather large "good" listening area (like the Magnapans). They were quickly set up which I am sure negatively affected the imaging and transparency, so I cannot form an opinion on those qualities. All three speakers really sound entirely different, but they all just have that "wow" factor, IMO, if you know what I mean. They were very fast and detailed but at the same time very musical, not harsh at all. They are probably good for the long haul. I guess a better way to say it is that the music got my attention, not the speakers.
Thanks, Dekay. I'm going to check these out for future reference. I've got my CLS's in a good place right now (both physical position and upstream equipment) but am pterry sure that I'm going to give in to a real full range speaker someday. I just don't want to lose what I get from my esl's to get low end extension. Right now the big SoundLabs are at the top of my short list but I'm starting to open up to the possibility of dynamic speakers. I've heard a few that I can live with but none have had the detail, transparency and openess that I've experienced with ribbons and, especially esl's. Thanks again.
Anybody own or heard the new ML Ascents? If that is what they are called - the model under the Prodigy's.
