Are "Used" Revel Studios worth the money??


I have seem great reviews for Revel's Studio speakers on the Web. They seem very expensive at retail; but, are a used/mint pair worth the money?? especially in comparison to their F-30 Model?? Or, are there other "used/mint" speakers out there for less money that are "equal" or almost equal in performance??? All comments welcomed and appreciated!!! Thank you

Please check my review out of these new speakers from Zu www.zucable.com We directly compaired the Druids to the Revel Salons on a complete Levinson system. These speakers are amazing! This is a truthful review to the best of my ability. I haven't stopped listening (or smiling) since we did the test.

I'm a big Revel fan, and have listened to the Salons, the Studios, and the F-30s pretty seriously. I think that each step along that price progression makes sense, i.e., that there is good reason for the Studios to cost significantly more than the F-30s. I think the price difference between the Gems and the F-30s is much harder to justify on audio-relevant (as opposed to cosmetic) grounds.
