I have the VR2's and was seriously considering an upgrade to the VR4's until I heard the Adagio's at the Home Theater Show in LA last weekend. The Adagio's better the VR's to my ear's for musicality, clarity, extension, etc. In short I am buying them. Frankly, aside from the top of the line MBL system, the Adagio's driven by Red Dragon mono's were the most enjoyable of all the systems I auditioned. I understand why the reviewer in TAS was gushing over these. Best I've heard for the price or even doulbe the price. BTW - that includes the Revel F32, the Hyperion's, Wilson Duette's, Von Schweikert's and many others I've listen to recently. Of course its always a matter of personal preference. Enjoy the hunt.
