Once you are connected to the Vandersteen sound you may find it difficult to accept another brands sound characteristics. There is something to be said for the rightness of the 1st order X-overs/time-aligment-baffeless design. I have had many other brands but always go back to Vandersteen
To return to the question...I would recommend a used pair of Vandersteen 3A Signatures. I have not had personal experience with the 2CE Sig MkII's, but I believe that the larger bass enclosure and hence the extended frequency response of the 3's are what places them above the 2's. The only other speaker I might suggest would be a Sonus FaberÂ…the Cremora, but that is outside your price range
