Where to purchase cables?

@squared80 Bet your rig sounds awesome.

NOT!

Head on back to AVS or ASR or whatever rock you came from. 

Power cords: whatever came with your system, because anything else won’t matter one single bit.

Speaker wire: any well made 12AWG OFC. Monoprice and Blue Jean Cables are cheap and effective. A coat hanger would literally sound just as good as any expensive snake oil brand but may be tougher to work with. :)

I've got WyWires (Blue series), Morrow (online) and recently Cardas. All are great cables---I've been very impressed with Cardas so far. I purchased the Cardas from Dedicated Audio (online)---they are excellent to deal with. The WyWires I purchased from other smaller local dealers. Let us know what you get. 

I suggest you investigate Analysis Plus. They make cables for audiophiles as well as NASA and other reputable organizations. They rarely advertise because they reputation precedes them and they thrive on referrals. They are not pricing cables compared to many companies that do advertise as esoteric cables, but they are outstanding. After a customary break-in. I believe you will find they are musically excellent

I'm another who utilizes the Cable Company.

It’s become my default approach.

I've found someone there I trust and I always work with him.

Thank you all again for your thoughtful suggestions!
