Preowned Focal 1027Be or New Focal Aria 936?

I'm considering purchasing a pair of Focal Aria 936 speakers that will be paired with an old McIntosh Mc2205 and C27 preamp. I've demoed the Arias at a dealer and really liked the way they sounded, but as is often the case, another contender has stuck it's head into the ring. Someone recently posted a pair of gently used Focal 1027Be speakers on Craigslist. I now find myself in a bit of a dilemma as to which ones to choose. Should I opt for the originally higher priced 1027's, or go with the newer technology of the 936's? The used 1027Be's are about the same, if not slightly less than the new Aria 936's. I have not yet heard the 1027Be's, but can anyone who has provide any guidance? 
Unfortunately, I've heard neither, but have been researching Focal quite a bit. The Electra series is higher tech and a higher line than Aria.  And you do not get the beryllium tweeter with the 936.  At the same price, I'd have to go with the 1027Be, unless a direct comparison indicated otherwise. 
Hard to choose, because the 1027be was back when Focal was known to make kinda “bright” speakers. The 936’s are unreal... but if you have some super smooth/warm tube amp/preamp, is go with the Electra’s. Keep in mind resale on Electra’s will be worse for obvious reasons.
