looking for advice on bookshelf speakers

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.

Timrhu Wow your the first person I ever heard that prefers the sound of a lower line in the Dynaudio product lineup.
As a Dyn owner I agree that turning them up because you want more. With the new focus series out there is a good possibility the dealer may have some good pricing on used.

It surprised me just how little I liked the 1.3SEs as I had high expectations. Got a good deal on the 110s so I thought I'd try them and resell them if they didn't work. I do enjoy them though, makes me want to look into the 140s.
Although I don't think my wife would care, the price of the C1s is more than I care to spend. I have considered the S1.4s but was turned off by the 1.3 experience. It isn't the first time I have preferred a lower model in a speaker line-up though.

IMO swapping the tweeter sounds like a bad idea unless you just like experimenting. It would greatly reduce the value of the Paradigms if you wanted to sell them.
