I have a D1x, K1x, V5x, just bought a pair of Merlin VSM-MM. After a long wait to get them, and a long break in period (100 hours so far, not finished), I can tell you the results are nothing short of amazing. Such precision and resolution, while being so smooth... No lack of bass (very tight and controlled, very extended highs. A superb match. I have JPS suprconductor 2s. I do recommend the Merlins with Ayre, no questions.
