Another Vandersteen model 2 question

I have the 2CE Sig IIs. I have never heard the 2ci model.

But I would like to add that although the Sig IIs sound good with my Line Magnetic tube amp, they sound much better with my solid state Parasound A21.  I suspect if one has a higher powered tube amp with much more current they will appreciate the power to sound their best.
Again the speakers really do sound good with a wide range of power amps, but I think to get that extra smooth timbre and range, to extract the natural sweetness out of them.....the more current the better.

Mr. V constantly upgrades his speakers as time passes, so even the same model can have different parts/sound. 
So, getting a more recent edition will give you slightly better reproduction than an older model. It will be noticeable but not earth-shattering.
I would recommend adding a 2w or 2wq sub (a pair is better) and keep the 2's you now own. The best part is you can still use them if you do want to upgrade.

At one time, I had both the 2ci and the 2ce signature.  I liked the 2ci better and kept them.

Bob. Not trying to start an argument with you, but the  2 Ci's are not even close to the new 2Ce Sig. II's. Other than the "2" designation and similar looks, they are two very different speakers. Years ago I had listened to the Ci at great length , considering a possible purchase. Even back then I couldn't get past their polite, reticent, lack of dynamics type of sound, not to mention the rolled off high frequencies and lack of mid-range resolution. The new 2 Ce's have none of these problems. I know it sounds like I am bashing the older Vandys, but even back then I wanted more out of my loudspeakers. It wasn't till the last couple of years that Vandersteen started making speakers (within my price range) that finally gave me what I wanted from them. That is why I have the  Treo CT's along with a 2Wq sub, soon to be two subs. (maybe).  If the OP wants to keep the Ci's, fine. I'm totally ok with that. Just that I believe there is a huge difference between the old and the new.....IMO:)

Thanks for the input. I agree with the comment about "polite" sound quality of the Ci but I personally don't find them rolled-off at higher frequencies nor the mid-range lack of resolution but all things are relative so I'm not questioning the input. I'm not discounting the input from mr_m but I have no doubt that improvements have been made. Perhaps it boils down to personal choice, just like any other speaker question. I'm fortunate to live a little over an hour away from Audio Connection and might have the opportunity to try the new models at home. Or I can take my amp and try it at the store. I also know there are lots of options in the $3K price range, new or used. At this point I just wanted to hear from folks with first hand experience and get an idea of what I might be missing.
