Office Digital Audiophile System
I've been thinking about putting a nice audio system in my den based around the Sennheiser HD-650 headphones. Don't want to take up too much space. I would rip my cd's to disc on my office computer. Then buy something like a Grace m902 Stereo Reference Headphone Amplifier (also has a built-in DAC) so I could it feed toslink or USB directly from the computer and then listen on the HD-650's.
Does anyone know of alternatives to this? How's the sound quality of the m902?
