The CLX is better than the Spire only if you do not intend to use sub with CLX. If you use sub with CLX it will be more or less like the Spire, that is, electrostatic panel and dynamic woofer. The CLX by itself will deliver the purity and unmatched precision in music reproduction guaranteed by the latest electrostatic technology. The CLX has double bass panels which produces adequate bass. Like Roberto says quality is there and some quantity. Depth and extension of subwoofer is missing. The CLX is better than Spire precisely because it does not have a dynamic woofer and one electrostatic technology produces the entire spectrum of sound. Except for perhaps the lowest octave. I would go so far to say that the CLX may be better than the 3 times expensive Neolith, just because it is one technology that is electrostatic technology. And not an amalgam of electrostatic and dynamic.
Just my two cents.
Have Fun!
