Magnavox CDB480 upgrade

[mmerig]

I would like to improve the sound of my cd player. I bought it in 1987, and it has always sounded harsh, especially for stringed instruments. I figured the harshness was the way CD's sounded, but now realize it does not have to be this way.

As I understand it, some of the players in this "family" have good digital filtering, (e.g., the 460, 465, 560) and others don't (e.g., the 470).

The 480 has the following chips:

SAA7210P

SC996S9P

TCA0370DP2

Is it reasonable to upgrade this player? Does the circuitry allow chip replacement/addition?

Is there a better transport ,with adjustable laser position, that will fit? (lower priority)

Thanks.
