First of all let me get set the record straight. I am, by no means, an audiophile. I also do not possess super human hearing. I am however an appreciator of fine audio, good engineering, and superbly crafted instrumentation. I enjoy looking at gadgets and drool over the technical details just as much as I enjoy using those gadget for their intended purpose (although that’s not always the case). When I decided to upgrade my then current headphones/AMP combo, the Denon AH-D5000 and beyerdynamic A2, I was looking for something that I could own for life. A combo that will serve me well in all applications and stay true for years and years. After much deliberation, the Sennheiser HD800 and HDVD800 were my choice.
