Alternatively you can use a set of ZEROs (www.zeroimpedance.com) which will allow you to use a tube amplifier and the highs will be just fine.
The high frequencies do not need a lot of power. but the overall sensitivity of this speaker is low enough that I would certainly question the use of the Cary- even with the ZEROs it might not be enough power!
