dedicated electrical line

Dedicated lines are the way to go. Also, put the breakers on the opposite phase of the fridge, install at the top of the rail if possible and clean the new breakers before they are put in. This is well worth the trouble and expense.

I read that grounding rods are supposed to be at least 6ft. apart .

So, if you cannot install a dedicated line, is the next best thing a power conditioner?

It is supposed to filter out all of the noise from appliances - isn't it?

I know power re-generation is probably the ultimate alternative, but it's BIG$$$

What are the drawbacks of conditioners?

Thanks

Our electric code requires ground rods at a minimum of 6' apart.

When I read up on power conditioners , I found that they impart their signature or had a sound . Just the same as anything else in the system chain .

I am assuming that you do have some interference problems , or noise , coming from your speakers . Can you identify the culprit ? Is it possible to eliminate the problem during listening sessions by unplugging or turning off the power ? Just a thought .

Good luck .
