I have tries all three methods and Stopped using bare wire one I used the following.
Here are my favourite connectors...
#1. KLE Innovations Bananas
Pro’s...
- extremely well engineered
- no colouration
- improves signal transfer over every other connector method/type
- extremely fast dynamics
Con’s...
- the fit is very snug, but they are made from copper and as such are not really meant for supporting a significant length of heavy cable.
- My cables have a 10 gauge neutral and a 12 gauge signal and the terminals (amp and speaker) are only 20" off the ground and I have no problems.
Other with longer lengths of cable to support have reported loosening or bending
#2. Furuz Spades
Pro’s...
- nicely engineered - i.e. they are very flat - no curved edges so they maximize their contact area
- Pure Copper of silver plate on pure copper
- comes in a variety of wire gauge and fitting type i.e. crimp/solder or screw clamp
- Being copper, clamping down on them makes for a pretty tight fit that does not loosen
Con’s
- not quite as detailed as KLE Innovations bananas
#3. Furez Bananas
Pro’s...
- nicely engineered
- Pure Copper or silver plate on pure copper
- comes in a variety of wire gauge and fitting type i.e. crimp/solder or screw clamp
Con’s
- not quite as detailed as KLE Innovations bananas
- easily bend if the banana is knocked of inserted roughly
- bends if heavy cable is used
I have tried some Furutech and Neotech bananas but to these ears they did not compete with any of the above products.
Hope you find it useful - Steve
