I too believe the Vandy KO is unlikely. The new speakers likely have a spike that at first seems like fidelity and in time you will hear it as artifact. First impressions are often misleading. Your amp may just not be up to the task for the 2CE. They do very well with Quicksilver amps, preferably at least 60wpc, 90-120 if possible. They do need some power to stand up and bark, or they will sound dark, muted, and lifeless. CJ amps seem to be a bit dark in my opinion, perhaps too much of a similar flavor there. For SS amps, the PSE IV, or V monos are great with the 2CE. There are may others which will work with that speaker. I think the new speaker is likely more efficent and sounds louder for that reason. Check the sensitivity of the new speaker. Do not make decisions too quickly, evaluation takes time....Jallen
