cable and interconnect advice?

I second stringreen's comment, I've found power cords to make the largest difference, then, for me, it's a tie between the speaker, interconnect and cables.
Also I second ghosthouse's comment, don't listen to us, reviews, audioholic bloggers, get your hands on a few different cables and listen.  I would not say cables are subtle, but I agree that the speakers are first, and electronics second, but the cables are right there too.  Listen to a few cables with your ears...you'll find which one works the best for your system.

I'm with Herndonb - I never fully appreciated the full improvements cables can make until I had installed excellent power cables.

I'd always found good speaker cables provided some benefit, but the interconnects were always marginal.

Then I upgraded my power cables and the whole world changed - now I can hear the difference most all cables make

Power cables would certainly make a change,and so does conditioning the power.Although isnt it really up the the wiring in the house( gauge,grounding etc). and the incoming power? Thats the thing i am understanding more.The condition of the supply electricity.On some level it all matters it becomes overwelming and expensive. My old house had 2 dedicated 20amps straight run into good outlets then a furman.
