I recently dug out a really really old VCD machine from the basement which I have not used for ages (house cleaning) and decided to have a listen since the machine felt pretty heavy, all metal, and looks well made (I don't even remember buying this). To my suprise, the stereo output sounds significantly better than my Chaintech AV710 24/96 output through the headsave tempo (pimeta) and sr325i.
So upon opening the case I discovered that the transport itself is philips (which I assume is pretty decent), the power board is fairly well made with big heatsinks and good deal of caps (maybe change them with better quality stuff?) and on the audio board I see one DAC and 2 opamps at the output stage of the stereo.
DAC = BB 1717E
Opamp (SMD) = the top line reads: 4558, bottom line reads 829C
There are close to 2 dozen caps with various size on the audio board as well.
My question is what are those opamps and is the DAC anygood? If it's worth my time to do some modding by switching out some caps and putting a BB627 on BD adapter in place of the exisiting opamp
