Any suggestions on the best connection for the amp side of the cables? Regular bananas seem to defeat the purpose of tube connectors.
Depends on your amp, & if you're willing to mod it..
Some people really like spades, others swear by bananas..
My little PS-Audio Sprout 100 only works with bananas, but the cable itself was still a big step up over my old zipcord with Tube connectors & low mass bananas.
Bigger amps can be modded to support tube connectors, but it will obviously void any warranty or support on the amp, but it should also add even more clarity to the setup.
