Fiio X7 mark II in like new condition with all accessories except the small pin tray. Trade or $560+shipping Audioquest Nighthawk with some small cracks in the wood cup but works as intended. Very euphonic, smooth, wide soundstage and clear separation of instruments. Very detailed and natural sounding. Just amazing what this headphone in this price category achieves. Lowest total harmonic distortion ever measured by innerfidelity I think. Lower than Stax and LCD2. Comfortable. Pads are in very good shape. An headphone that you need to hear at least once. Trade or $200+shipping Almost like new CD900ST with original, unbranded box with very little inside. Came directly from Japan. Here is my take: big bass, pleasant and natural midrange, smooth treble. Small soundstage. Rich sound. Sounds big and fat. Install very close against the ears without excessive pressure. Comfortable. Trade interest: HD800, VModa M100, NADVISO HP50, HD6XX, Audio Technica MSR7, Audeze Sine... open to suggestions.
