What the best 89-90 db speaker I can buy for 3k?

This weekend, at the Capital Audiofest, I happen to hear the Odyssey Lorelei speaker ($2,700) in a reasonably priced setup (something like $5,400 for amp, preamp, speaker and cables). This was a terrific sounding setup for the money. The sound was full bodied, which is particularly suited for classical music, and had reasonable weight and scale.

In Classical music, which is 90% of what I listen to, dynamics are many times greater than in other music, the lack of same makes things somewhat "dead" no matter if the tone, imaging, scale etc is spot on."

I agree, but every piece in your system contributes to this. It makes much more sense to look at what the whole system will be than just the speakers. If you mess up with one of the other components, you can loose the dynamics that you are looking for even if the speakers are capable.

Rest of system is quite dynamic.

AudioKinesis, most of their speakers are 93db effciency. But only the Rhythm Prism is in your price range. I have no experience with this brand, but the guy that sold me his pr of Thiel CS2.4 a while ago told me that he was upgrading to a pr of AudioKinesis due to their high effciency and the CS2.4s lack the dynamic contrast he was looking for, so it looks like you are looking for the same thing. Worth a look, but don't blame me if they don't sound to you.
