I know that feeling as well, although here I speak of listening to older music on a radio of the same vintage (I no longer have any of the old TVs I had before I moved here nine years ago.
) I sometimes listen to an oldies radio program on weekends; I swear, it sounds better to me on my Zenith K731 or C845 than through a modern radio, or even my Aiwa stereo (1999 vintage). I guess it may be because of the better audio circuitry, larger speakers, better bass response, etc. of these old sets. They certainly don't make them like that anymore.
