I've heard VSM Merlin at friend's in a Air tight then Transcendent' OTL configuration. It was really impressive in a hifi way, but I could not live with this kind of too revealing speakers. I felt flesh and blood was missing. A LOT of transparency and airness, wonderful delicacy. But you know, my friend actually sold them to buy french pro speakers's GKF. He even tought to get proac instead (but not enough efficiency). I had proac resp.2 and now 2.5 and am very happy with them. Not impressive as Merlin but simply musical in all way. I can forget hifi with proac 2.5, not sure I could with Merlin.
