    I picked up this CD player a few days ago, and finally had the opportunity to hook it up, and give it a listen. It's a 1st generation player, with the TDA1541 DAC. The transport is a CDM-2. Totally amazed at the sound. Clean, crisp and clear. Nothing overstated. It's a KEEPER!

    CDB-650 is a personal favorite. Good with everything but not great with any single CD.

    That was my second CD player I got way back in the 80's

    First-gen players from Magnavox/Philips were 14-bit, 4X oversampling.

    Yours is 16-bit, 4X oversampling.

    I had a CDB-460. Same chipset family for DAC and filter. Mine might have been a '1541A--or maybe not. The '460, '560, and '650 were the first Maggotbox models released with the 1541-family of chipsets.

    Audio Magazine ran an article on how to upgrade the unit with a few resistors and capacitors. I did those mods to mine, I think that was my first electronics soldering job. As I recall, the little resistors were to drive an existing op-amp chip into Class A operation. I think I spent about $20 at Digi-Key for the parts kit.

    The upgrade was authored by a "famous guy" who's name I don't remember. He was associated with POOGE (Progressive Optimization Of Generic Equipment) and in fact I think he invented the term. He had a more-extensive modification for the Magnavox/Philips players, the Audio article was the abbreviated/simplified/condensed version.

    Yup, that's the article.

    I looked around for it on that site, and either missed it or gave up too soon. Just re-read it. Brought back memories. I moved on to an Adcom GCD-600 which also uses the 1541 chip, but I think it uses some other digital filter chip than the Philips. Gave my '460 to my in-laws who used it for many years, then threw it in the trash for some reason. I suppose it started skipping, or they dropped it when dusting the shelf, or somesuch.

    I've done a lot of that too since discovering the archive. An index would be really useful. I guess they worked on indexing the early stuff but threw in the towel after the 1969 issues.
