Electrical Ground to Water Pipe, No Earth Ground


I live in a house built in 1965 that has an older electrical panel, the with the spring-loaded breakers. I had an electrician to come out and do an inspection of my home's electrical system yesterday. When he checked out the panel, he noticed there is no earth ground to the panel. There is a ground wire going to the main water pipe, however. The electrician told me that the system is electrically safe with a ground only to the water pipe, but if a car were to hit a nearby utility pole we could end up without electricity to our home. He said that if we had an earth ground, if a car were to knock out a nearby utility pole we would still have power.

I want to get an earth ground installed and plan to do this. My question:

Does not having an earth ground to my panel all these years cause a negative effect on the various audio systems I've had? Does this affect things like bass weight, or solidity of the image etc?
Thanks.

Great answer by Jim, as usual! Regarding ...

From a technical standpoint I can't envision any way in which an absent or ineffective earth ground could affect sonics in those or most other ways. And I'll add that I too have an older home (1950's in my case), and until I had the electrical panel replaced and a couple of ground rods installed several years ago I too had the panel grounded only via a water pipe. During the approximately 30 years I was in that home prior to the electrical upgrade, those years encompassing several upgrades of my speakers and various other parts of the system, I never sensed any lack of bass weight. Or of imaging and dimensionality, at least once I had moved to tube amplification many years ago.
