I run three dedicated lines from 20 amp breakers using #10 solid core romex.Not a fancy professional job, but the results are worth the effort.
I run one line directly from the panel into my Shunyata power conditioner using a Furutech 20 amp connector.
Each power amp is also wired direct from the panel with Furutech connectors at the end of the wire and at the amp.
I was using mostly dIY room treatment,but in March I bought 2 ceiling mounted clouds and 4 corner traps for the wall behind my Acoustats(floor to ceiling).
I have a half trap 16 ASC trap in my third corner, the fourth corner is open to a stair way.First reflection points and the area behind and in the centre of the speakers are currently DIY absorbing panels, which will be replaced in the future with GIK products.
I also have an array of ASC mini traps on the wall behind the listening seat and a DIY centre absorber in the centre which I will also replace with a GIK product.
The power and room treatment aspects of this hobby were always put on the back burner,only to be considered when I had found a system that I could live with for the long haul.
I am sure in hindsite, had I addressed these issues in the past I could have saved myself a lot of money and frustration flitting from amp to amp, speaker to speaker.But that's all part of the game.
However,the room and the power delivery affects everything, so do it right and whatever you have will sound it's best.
A lesson learned, but never too late.
