what speakers for 4k or less new or used

Check out the offerings from Green Mountain Audio. The sound of the Callisto is stunning.

The Tyler Acoustics Linbrook Signature System 2 piece (the one with the bass modules) can be had used in your price range for 3-4K (5K new).

I own a pair of these, and I can honestly say that I have not heard anything I have liked *as much* until you get to the Von Schweikert DB99 mk IIs, (and they are just shy of 10K a pair new). There are better speakers I have heard above 10K, but value-wise, the Tylers are tough to beat. Definitely worth seeking out a home audition, IMO.

One other possibility in your price range used would be the Dali Helicon800s (4K used, 6K new). I rate the Tylers as better, but these did stand out from the rest of the pack at their price point, and they are sold in stores (so they are more readily available for audition). Also worth a look, IMO.

Shahinian Obelisks. If you have nothing against a polyradial design they are the cat's meow in this price range. Midrange to soothe the soul, and very fine bass and high end extension to boot.

Magnepan 3.6R (about $3k, needs a TON of power, min 400W/ch at 4 ohm), Magnepan 1.6QR ($1k, a lot of power, and a Vandersteen sub for about $800, makes it a great system), Gershman Avant Garde, Gallo Ref3, Vandersteen 3A Sig, or 2CE Sig, Paradigm 100 V3. If you have the room, I know they are not new, or fashionable, but the Klispch Klipshhorn has such a great distinctive sound.

Alot of good recommendations, I'll add VMPS RM 40's, an outstanding speaker for the money. You really need to listen to these as they all sound different. Some people love planars and some people can't live with them and must have cones. The only way to tell what you'll like is to listen to it and hope it sounds good in your room.
