Dedicated AC Line or Upgrade Equipment?


I am wondering how many of you out there have dedicated ac line for your audio system. I have heard that getting a dedicated ac line does wonders for your system.

By dedicated ac line I mean either having a sub-circuit totally dedicated to your audio, or in some cases, running a separate 20-amp ac line with its own electric meter. In the extreme case, I have heard that people have bought power generators (no - not the PS Audio kind) to power their entire audio system so that they can get the optimal audio performance.

I am thinking about upgrading to a class A amp on my system. However, I am concerned that without a dedicated 20 amp line, I may never get the optimal performance out of the class A amp. For example, I currently bi-amp my main left/right speakers with a Krell KAV-1500 5 channel amp (class AB). In the owners manual, Krell advises using a dedicated 20 amp line to get the optimal performance out of the amp.

So is it a moot point to even think about further equipment upgrades when the source of my audio system is not optimized - that is, when I don't have a dedicated ac line.

I like to hear from people who have experienced with dedicated ac line and whether they think it is worth getting a class A amp before one has a dedicated line.

Thank you for sharing your insight.

I have the krell kas mono blocks and have two 30amp dedicated ac line to it. If you don't plane on haven a dedicated ac line than don't buy class a.
My electric box is all used up. The electrician said I would need an entire new box/electric upgrade for about $1700 or he could run a sub-box for about $650. Either way, it's not going to be an inexpensive tweak. He would run the sub off a 50 amp circuit that is dedicated to the heating system. It is an older house that used to be all electric heat and may have needed 50 amps, I don't know. I now have a high-efficiency heat-pump which I doubt ever needs 50 amps. Would a sub-panel in this arrangement "dirty" the current to my system? Would I only be able to listen on warm days? Which option would you go with? Any advice appreciated.

Agree with G M C and get the JPS cable and the dedicated lines. Also, Joe at JPS gave me some great advice on setting up dedicated lines, etc.
I installed dedicated 20 amp. 10 guage outlets and my wife noticed the difference in the picture on mitz 65907.
