Bare wire speaker and amp ends, sounds best.
@roadcykler +1 LOL 
If this was true why don’t you ever see or hear six & seven figure systems running bare wire.
Building Speaker Cables
I have decided to build my own cables. For the cable I’ve chosen DH Labs T-14 cable for the cable connectors on the speaker side will be Furutech FP-201 (G) spade connectors, amp side will be Furutech FP-200b (G) banana plug connectors. Would it be overkill to silver solder all the terminals before sealing the connections with marine grade shrink tubing?
