A friend has a pair of these speakers. I really like its overall tonal balance, ability to deliver the proper density of sound (harmonic structure) and the lack of artificial edge or brittleness. Overall, a terrific speaker.
The slight shortcoming with this speaker, like a LOT of other speakers, is that it is not the last word in liveliness and ability to deliver the kind of explosive attack that other kinds of speakers (like horns or full range drivers) can deliver. I would try an OTL amp with the speaker. OTLs have a way of bringing to life speakers that are slightly "polite." If I were you, I would audition something like the Atmasphere and Joule amps.
