Best imaging and sounding bookshelf speaker


I have a pair of Spica TC50's (crossover recapped). I'd like to hear your opinions of what you all think is the best imaging and sounding bookshelf speaker. I will always own my Spica's but I also own a pair of Apogee Centaur Majors. I simply haven't found a speaker that images as well and sounds as natural as the TC50's. Thanks in advance for your opinions.

By "bookshelf" I assume you include stand-mounted. I have a pair of Sonus Faber Electa Amators that are imaging stars. I have heard the B&W Silver Signatures that are also outstanding.
Totem Sigs I's DO as Mattmiller said, image well.
They also have great dynamic range , fully as capable with a symphony as a jazz trio. My summer pre,a Bryston B-6 overloaded on my most dynamic CD
before the Sigs did, had to put my EE Avant back to work which
also has great dynamics.
These I have owned and can recommend: Dynaudio Contour S1.4, Vienna Acoustics Haydn Grand, KEF LS50s, Evolution Acoustics MMMicroOnes, Volent Chorale CL-2.

On my to own list: Vapor Audio Cirrus, Nola Boxer, something in the Monitor Audio Platinum series-P100 or P200.

Best of luck with your search!
I bought my girlfriend two pairs of Spica TC-50s for her new house. When paired with decent electronics, they are hard to beat for the money. They image well. Base is more than adequate. And off-axis listening is surprisingly good.
Soundfield audio monitor 1 and speaker art super clef. Both are quite scary with the right amp
