With due respect to 'Marakanetz' mention of using xlr connections, and bargain basement cabling, ($20)... if the power train is truly balanced topology front to back, that alone will enlist another level of quiet, or blacker background... That was my exp using an all BAT power line... and I did use some $35 xlr cabling. AT FIRST.
Someone mentioned I should see for myself how cabling can raise performance, and I did just that going to the Cardas Neutral Ref xlr's. The Diff was night and day. Following having a decent pair of ICs inline, I began trying power cords... Whoa! Things got even better!
The thing is, philosophiess and opinions around here are a dime a dozen... or less... so the decisive factor will be your own ears... ALWAYS. If ya hear a diff and like it, and are willing or able to pay for it, do it. If not? Well... yayy you.
I can not afford to pay for sheer egotisim. I pay only for what I percieve as sheer improvement. Now and then, there is a sideways step, but not too often.... again, I simply can't afford that luxury.
A severe lack of open mindedness and the subsequent lack of attention to cabling in my first rig was indeed the issue... not the components, by and large. That turned out to be a quite costly undertaking.
The above note on the Monster plc also has some weight. Via the CAble Co. you can try some plc's as well. PS Audio, Running Springs, Audio Magic, Pure power, are all good items with good technology built in.
Very good luck to you.
