check out the Cayin unit, great tube sound, great value.
headphone amp
Looking for suggestions for a headphone amp that will drive either grado or sennheiser phones (low to high z). Something that retails for under a 1 k $. Have considered the Creek amps and the Grado amp - any experience with these (and what phones wre used with the amps), or other recomendations for amps in the 1 k $ retail and below would be appreciated?
