I couldn't justify having the Marantz 6300 with the MMF-5 sitting right there. It was only a matter of time. I should probably lie about this so no Marantz fans get teary-eyed but I parted out the 6300 on eBay. It had cosmetic problems and minor functional problems. I bought it for something like $74 (an auction with problems disclosed), got a few years use out it, and made probably $300 selling parts.
