Excellent advice thus far. I moved from my 1C’s to 2CE Sigs in a matter of a month (got very lucky with someone selling his 2’s for a very very fair price), seriously, as I fell in love with the 1’s sound and wanted more. You would not loose anything moving up, IMO, only gain more of what you already like about the 1’s.
The 3’s should work nicely for you if the price is right, but as Jim @tomic601 stated, the new 2 model III’s sound to be an incredible solution as well, as would be the Treo’s, but I would assume a larger investment.
I don’t think you can go wrong with any of them. BTW, I still have the 1’s as ‘rear’ speakers in my HT set-up, and comforted in that they are solid back-up speakers as well. I had to do that while getting one of my acoustic couplers repaired. Was nice to have them at the time, but could not wait to get the 2CE Sigs back in operation. Big difference.
