I am selling a Music Hall MMF CD-25 upgraded with Burr Brown OPA627 opamps. The player is in great condition. The face and upper housing have a couple blemishes, otherwise the player is pristine. Overall, I'd rate the condition a conservative 8/10.
The CD-25 sounds amazing right out of the box, but the upgraded opamps add an obvious improvement to the sound--they make the player much warmer, more responsive, and less "digital" sounding. This player is considered to be a giant killer by many reviewers and can easily compete with CDPs in the four-figure range.
I am asking $400 shipped to anywhere in the US; I will ship internationally for a slightly higher price. The player comes with its original box, packaging, documentation, power cord, and remote. If you are interested, send me a PM, email, or reply here. Thanks for the interest.
