The Hi-Fi Man has excellent headphones, but they require a powerful headphone amp, as they are a difficult load. The Audeze LCD-2 (Revision 2) would probably be for me my favorite. They are easier to drive than the Hi-Fi Man phones and are more comfortable to wear for extended periods of time. Of course, all great phones require great headphone amps to sound their best, but with the Audeze's you can buy from a larger range of headphone amps.
