I am not arguing with what’s in that post, but I think it’s a cut and paste from something I remember seeing somewhere else recently. The Absolute Sound, maybe?
And as far as what it says, I won’t argue with anything become I am a pure ignorant novice on this stuff, but I cannot help but feel that a dedicated run of 12-2 (although 10-2 may be better) has got to be superior to running your audio off the same circuit all sorts of other household stuff is on.
Yes, you are correct, I am giving him the credit for someone else’s work. it is from Absolute Sound. Sources should always be made clear if posts are not original.
I have 10 gauge on a dedicated line but it has been so long ago I can’t recall a huge difference putting it in, but for sure it is one of the first things an audiophile should do. If one had a long run from their panel to the hifi they would have to be pretty "dedicated" to use 6 gauge, then drop it down to 10 gauge in order to fit it in the receptacle, but many audiophiles have spent more money on things that probably have less benefit on the sound quality.
In line with this thread though, I am confused why you need 3m power cords though- most people have the components close to the outlet or power conditioner and have longer interconnects to the amps, or longer speaker cables.
