I'm a neophyte at this, let's get that out of the way first.
I assumed, or had read, that much of the problem (for me glare and glassy nature at the top end) came from ground noise. A residential electrician I spoke to thought that most of it probably came from the "hot", but he was willing to do the seperate grounding rod at that time. Glad I didn't ask him to. He probably didn't know better and would have done it. Other posters here, including Al Sekela, have said it's very dangerous in the event of a lightning stike.
I have a few strikes ahainst me, as I have CD's, not vinyl; like rock and adult contemp music, and like it pretty loud; have revealing Thiel 2.4 speakers, and at 87 db, have settled on Solid State amp for power (ayre); use BAT tube pre-amp and Cardas GC and GR IC's and Speaker wire.
Thanks,

Didicated powerlines need isolated ground cable but - cheap-Jack 07:57:40 04/04/07 (2)
Hi
NOT, repeat, not detached ground rod(s).
As already mentioned, hundreds of thousand volts can exist btween the two detached ground rods in the event of lightning strikes. Fatal to any live beings happened to be there. Can your house accident insurance cover the claims?
All isolated & INSULATED ground cables (size same or larger than the gauge size of the powerline conductor) should be grounded to the same grounding point of the fuse/breaker panel.
Of course there may be exception for major computer or digital installations in old old buildings the where existing ground rod is too ground resistive, & isolated dedicated ground rod may be a better option subject to the jurisdiction of the building inspector.
In my situation, the dedicated insulated OFHC copper ground cable running parallel with their respective dedicated powerlines for both anlogue & digital gears are terminated at the same grounding point at the water mains entry pipe where the fuse panel grounding point enchored.
I periodically inspect this central grounding point at the water main pipe section to ensure rustless/diretless grounding contact made. This is the very spot in one's house most commonly neglected.

  Thanks Jack, apprecite the advice.
  So, what is the best way to reduce ground borne noise? I suppose it exists, even on a dedicated line.
  Also, my audio is in a detached garage/office. The breaker panel there I believe is a sub panel from the main house. I am wondering if it is more cost effective to have a seperate a/c service brought to the garage from the utility company? I can shut off most everything in the garage office when listening pretty easily.
  or... power regenerator?

    Hi.
    Of course, the expensive yet ideal way is to put up a small generator to your audio haven in your garage.
