I don't know whether separate grounds or a common ground would give better results in all systems; I suspect each case is sufficiently different that it is worth having the ability to try them both ways. One can always tie the grounds together at the audio system if each circuit has its own ground, but if there is only one ground wire installed, it cannot be divided.The outlets are usually so far away from the safety ground-neutral-earth tie point at the panel that the safety ground wire is an antenna for noise. This is why some folks do dangerous things, such as having a separate audio ground rod or lifting the AC safety ground, and get improved sound. A grounded metallic conduit with insulated equipment ground wire that is tied only to the outlet ground sockets provides some measure of shielding for the AC safety ground wire. Perhaps this is what you had in your previous installation.
