looking for advice on bookshelf speakers

A simple option to smooth and lessen treble energy, without the pain of experimenting with costly component changes, is an equalizer. It may not be audiophile accepted, but who cares if it helps you listen. You might check out dbx models readily available at chain guitar/musician stores. Simple, cheap, and effective.

full bodied

Atlas interconnects equator mk2 or atlas titan (if you can find) presents full bodied sound with grain free highs.

Dynaudio Contour S1.4. Extremely smooth. Fritz Carbon 7, also smooth.

proac 1SC's will do the trick, used, of course.

At low to medium volume levels, I find the sound of my Jolida 102B driving Totem Model One Signatures to be very musical, dynamic, and nonfatiguing. In fact, one of the few criticisms of the Model Ones in numerous reviews was a little reticence in the high end. As I've mentioned in prior posts, don't let the relatively low power of the Jolida deter you. Generally speaking, I've found tubes to provide a mellower, more engaging musicality, particularly when compared to less expensive solid state. Of course, I've upgraded tubes and cabling to further improve the sound.
