All instruments come to live with pm1, crystal clear and smooth at the same time. Pm1 made my Sennheiser hd650 and Grado reference 1 sound harsh and incomplete. I had some time to listen to hd800 and Audeze lcd2 but both failed to pleased my ears. To me the pm1 is a bargain in headphile world. The sound, the build quality and the comfort is second to none in my opinion. If pm1 was produced by a big name headphone company, they could easily get away with doubling the price and still sell it like a hot cake.
