Gently used Citypulse DA2.03e headphone Amp. I've owned for several years and it sounds amazing with all sources; I used it exclusively my Sennheiser HD650 (listed on eBay) with the optical in and an Apple AirPort. Can also be used as a pre-amp. I had to replace the internal fuse once, when I first got the unit but has worked flawlessly. Includes remote control and Monster Cable Power Cable and PowerCenter. Free Shipping. No fees for PayPal.
