I remember the first time I went to a live classical music concert years
ago.  I thought the music sounded "tinny".  At that time I was
accustomed to listening to music on AM radio using an old tube-type
console set with a big boomy speaker.

It's all what you are used to.  If you switch from a receiver with lots
of high-frequency rolloff to one with a flat response, it will sound too
harsh until you get used to it.
