Terminating Cables

I'm not sure what you're unsure about. Bare speaker wire (ends) is best. Plenty of threads and posts on this forum advocating for one way or the other though.

If you're unsure about "just ramming the cable in the holes and hoping for a good connection and good sound", shouldn't you feel that way even more so about the workmanship and overall end result (sound) if you did have the ends terminated?

I strongly agree that bare wire sounds best if possible. Some amps however, do not have binding posts that make it easy to use bare wire, especially if you are running a bi-wire setup. 
The majority of terminations out there are brass with gold, silver or rhodium plating, all of which tend to degrade or change the sound quality and tone from that of the bare wire. A good quality real copper termination is hard to find, especially a banana. The only ones I found that I really like are sold by Douglas Connections. Don't fall for the fake "copper" connectors from China you may find on E-Bay. The Douglas "Furez" line of spades and bananas sound great, are not overpriced (around $60 for 8 ends), and best of all they have a version that you do NOT have to permanently crimp or solder to the wire, which allows you to re-use the terminations on any wire you choose, or switch between banana or spade for different amps and speakers!

I don't know which speaker cables you are using and that might be a helpful bit of information to provide ;-)

While I do agree that bare speaker wire is a very good way to go I also want to suggest a DIY remedy that is very easy and sounds very good, to my surprise. Check out these two threads and feel free to PM me if you have any questions.

@mancub1 - the KLE Innovations Banana plugs Lak refers to should be soldered. I use WBT 4% silver solder.

They are not really designed to be crimped. But in this case it would appear that the solder does not really impact the improvement in sound quality too much.

They are precision engineered to fit "snugly" as opposed to tightly into the binding post, but they will maximize the contact area of the plug and minimize, maybe even eliminate, the possibility of micro arcing.

Give them a try - I was surprised at just how good they are also - and I’ve been using KLE products for over 4 years. - I should have known :-)
