I've been having them about a month now. I got them on closeout for $400 and this is my second pair of planar cans,I had a stock pair of Fostex T-50 RP about 10 years ago. I absolutely love the detail retrieval and the clarity of planar drivers. I listen to a variety of music everyday from Cincinnati Pops Orchestra to Pantera and the Anandas sound great with no EQ needed. I sold untra high end audio equipment for a few years awhile back but got to listen to some world class Focal,Wilson Audio,Magnepan, Krell, McIntosh and other brands. My point being I really don't hear any difference between DACs but I would like a little more power for the Anandas and am looking at the IFi Audio Zen Air DAC.
