Besides the "usual suspects" among which I think you definitely should audition Vandersteen 3A and 3A Signature, there is a not-that-well-known speaker from Canada called Gershman RX-20 Avant Garde. These, like the Vandy's, and IMO unlike the Silverline Sonata, do go down to 25hz with a power and authority which is almost never heard in this speaker price range. Gershman's give a great soundstage effect both from side to side and front to back, have great imaging and a pure clean midrange that some have described as almost electrostatic. These speakers have been winning best-in-show awards at recent hifi expositions. On the complaint side, some have said they are too laid back in the high end. Nevertheless, they are smooth in the high frequencies, if not overly prominent. They are never harsh or strident. You may need to consider cabling which favors the high end slightly, depending on your taste. Because of the bass, they require careful set up and a room which is not tiny in order to avoid bass bloat. You will probably have to locate them away from the wall by two feet or more. These speakers are definitely warmer sounding than either the Sonatas or the Coincident Super Conquest/Super Eclipse. This is not to disparage the performance of Silverline or Coincident, but just to get you to look at all your alternatives in order that you may decide according to your personal taste. They are slightly less than 40 inches high, have a small footprint and have an exceptional beautiful finish which comes in a lacquered high gloss black or burgundy, among others. Cost is $4400-$4800 list, depending on finish. They are difficult to find, but definitely worth an audition.
