Used Bookshelf up to $3k

I own Dali Epicon 2 bookshelf speakers in a 2nd smaller system and they are phenomenal in my opinion. Very detailed, good midrange and really nice soundstage. 

I just saw a pair listed at TMR for an awesome price.

To answer your question I auditioned a pair of B&W 705 S2 and S3 in Rosenut and Mocha respectively with their matching stands.  They look beautiful and are well built with the tweeter on top.  They sounded good in my medium sized room but were a little too sibilant over time for my ears.  I also tried the KEF R3 Meta with their matching stands.  I went with Revel M126 Be in Walnut.  They are just as beautiful but the beryllium tweeter is much smoother.  The next best I heard were the Philharmonic BMR Monitors in curved Ebony.  A beautiful looking and great sounding 3-way standmount speaker.  

@troutbum , A 3 way bookshelf speaker would qualify as something different. Since they make up a small percentage of that market, it would significantly narrow your potential search options down (compared to the available 3 way stand mounted speakers).

I'd go along with those recommending Fritz; you should be able to get a new pair for around that much, but used can be even better as those things can take a long time to break in.... 

From personal experience I would recommend to give Fritz a try as well. Very fluid & engaging midrange & vocals. 

Lots of good speakers out there though.
