I've never owned the 1's, but heard the 2ci's at a NYC audio show in 1989 and the music was magical -- it just sounded "right" to me. So saved up my pennies and purchased a pair. Still remember moving them to my small apartment via 5 blocks via hand truck through Manhattan from the old Sound by Singer as I was way too poor to afford shipping. Thirty years later I've gone from those to 2ce Sig to original Quattro to the Quattro CT's and now looking forward to hearing the upcoming Kento's.
Agree w/most of above posters, I didn't perceive what I would describe as sibilance in the highs in the 2's -- but going to the much more expensive Quattro CT's did provide what I'd describe as a more open/extended upper range. I suspect that you'll find the 2's or 3's will be provide a "warmer" balance and probably fuller sound than the 1's but still retain the wonderful mid's. Might also consider auditioning with a tube pre-amp and/or power amp (?).
Can also add a 'thumbs up' to Hifi Buys in Atlanta if in the Southeast region. Good luck!
