Matt, contact me via PM at Audiocircle, compaudiophile or audiocircle and I can email you the pdf of the full UHF magazine review of the Kithara. (I have the print issue)
Nothing near it price will equal it, IMHO.

From a "for sale" online advert:
For sale here is a pair of the Oskar Kithara speakers, featuring the Heil AMT (Air Motion Transformer) tweeter, a completely design from ordinary dynamic tweeters. Not only does the Heil AMT have a huge frequency range - from 700 Hz to 23,000 Hz (!!), so no cross-over in the critical and easy-to-hear range - the highs are clear and non-fatiguing, unlike the many ear-bleed inducing metal tweeters in use nowadays. The up-firing 10" woofer provides all the bass you'll need
Set-up properly, these speakers image like crazy and provide full range sound, and with an efficiency rating of 94dB, you don't need a lot of power to operate them.
To quote Gerard Rejskind at UHF magazine in their review of the Kithara:
"This is a loudspeaker that any of the world's great speaker designers could point to with pride. Its highs and midrange are topped by only a few, very expensive speakers. Its bottom end is solid and more then generous. It will run with nearly any amplifier. It can work even in large rooms. It has a killer image. Is there anything on your list that I've left out? I have a feeling that if this speaker is ever produced in large numbers, its price will have to rise. At the moment it's absurdly cheap. That's what I'm telling my friends."
