Need help buying new speaker cable

If you like your current cables have them refitted.

Otherwise, all the brands mentioned our reputable. All cables including power, speaker and interconnects are important and there are vast differences between them if one knows what to listen for and differentiate. However, all marketing crap is just that. These all have to be put in your system and listened to. 

What I can't figure out is why it drives people so batty that some people want to spend money on cables?

"Show me some engineering data that that wine you paid $60 for at the restaurant was really worth it."

See how ridiculous that sounds? We know there's mark up and we enjoy it anyway. Thing with cables is, there may actually be a difference that people can hear with more expensive cables and the mark up is worth it.

So, either there is no difference between cables -- and people like to pay more and enjoy the illusion.
Or there is a difference between cables, and people like to pay more and enjoy the reality.

Either way, those trying to "save" the cable spenders need to relocate their charitable efforts to people with actual problems, not first world discretionary spending problems. FFS, do some good where it's needed.

Hello,
I think you can repair this yourself. Straightwire sells those ZBanana ends. Also, Straightwire has very nice cables that dont

Fix Em!

Why not do it yourself?

If you send them in, you never know how 2 weeks can turn into 3 ...

You can use lamp cord, put your own connectors on while you wait, then hear the difference when they return fixed.

I would recommend spade connectors over banana plugs if your amp and speakers can handle spades. 
Most banana plugs allow for spin which means there is not a solid connection. 
But you mention you aren’t able to hear differences in cables so I wonder if your system is resolving enough for this level/cost of speaker wire.
