Should I buy "NEW" spker technology or "OLD"??

I have been pulling my hair out over the following dilemma: Should I buy "older" speaker technology over "new". I realize the major parameters that determine the outcome of such a decision: electronics, room size, type of music, budget, etc., but I would like this question addressed from the "standpoint" of: what is a better value and what has more performance potential?? So here it is: I have several times considered over the last year buying either a "used" pair of Audio Physic Virgo II, "used" Thiel 2.3, "used" Revel F-30's and even "used" Vandersteen 3A's(the Vandy being the least favored in the mix.) Nevertheless, a new dark horse has come onto the scene, but it is not "older" technology or on the "used" resale block. It is the Meadowlark "Osprey" speaker which is finally arriving in showrooms. Other posts on this site have offered some evaluation of this new model which uses a new transmission line technology, high quality drivers, and cabinet material, etc. The returns are early and none conclusive as to the overall "performance" of this product. I have heard the Thiel 2.3, Virgo II, Revel F-30's, but not the Vandersteen 3A's. I can't spend my days and nights auditioning. I know each of these speakers have strong advocates on this site, especially the Vandersteens and AP's.... The Virgo II were "MAGICAL" when I first heard them (but less so every other time,I happened to hear them which began to turn me off) and every owner and ex-owner seems to think as much. The Thiels and Revels, though, clean, neutral and coherent were not as "boxless" and airy in their presentation as the Virgo II which is its "core" magic and strongest performance skill. Nevertheless, the question is whether the technology that was built into the VirgoII which made it a run-away bestseller, can/will that be superceded (and also its sound) by the technology that the Meadowlark's "Osprey" now offers. I realize this is as much a matter of personal taste as speaker engineering, but I am curious as to what others think about the simple issue of buying "new" versus buying "used" ESPECIALLY related to these particular models. Finally, let me add, that I clearly recognize that some speaker designs are just so good that they remain to outperform even what is new. The vintage speaker market, that is, models of the last 5 to 7 years, I think proves this out. All opinions welcomed!!! Happy Holidays To ALL
