I did ... flabby bass IMO even after putting on a pure silver cable. Go figure I think as @crabdog pointed out the bass is disjointed from the rest of the spectrum. Though the mids are decent i feel the overall SQ is marred by the flabby bass. I tried different sources too including the zx300 and fiio m6 as well as the iDSD BL. I will give it another listen just to be sure the third time!
