Zu Druid MK IVs vs. Essences

I'm trying to decide between these two speakers and, after reading lots of reviews and impressions on-line, I'm more confused than ever. I'd like to hear what differences Audiogoners have experienced between the two. Of course, I'm not looking for the final word, or consensus - just folks' subjective impressions.

I won't get to audition either speakers, because I'm in northwest Wisconsin and a bit isolated. But I've bought a fair number of speakers without hearing them, so that doesn't worry me. I like revealing speakers that are a bit upfront and I'd rather have scintillating highs and great mids than thundering bass. I even like a little thin-ness in the bass.

Thanks in advance for any impressions you can offer.
