Musical Fidelity Tri-Vista 21 DAC for sale. I upgraded the tubes this year ($330) and have put about ten hours on it since. I'm selling it because it was replaced with a PS Audio unit that doubles as a preamplifier (I sent it to North Carolina to have the tubes upgraded which took about three weeks). Comes with the original box, original owner's manual, and certificate of authenticity. It is in excellent condition with no visible scratches (there is a little bit of dust on top in one of the pictures). Rating is for age only. Please ask if you would like larger photos. Will ship to contiguous U.S. only. If paying by check, it will need to clear first. Uses four 5703WB tubes.
