One thing though..the screw in banana plugs?
I had some problems with them loosening off as well as them easily slipping out the sockets of a couple of amps I've tried them with, though they are fine with my current amp.
I think they are maybe slightly smaller than 4mm?

I have a set of THESE:

which could be soldered in?

Any advantage over whats fitted as standard?

Or what about these?

I had the same problem with the screw-on terminals coming loose over time, which I cured with some shakeproof washers - £0.20p from the local hardware store. A drop of Loctite on the threads could also work well.

You can gently lift the splines on the banana plugs with a small screwdriver and maybe slip a small length of thin copper wire under a couple of the splines to make it fit tighter into the socket. A bit fiddly perhaps but it is a permanent solution for any banana plugs with splines.

"Z" plugs are better than the vast majority of inexpensive 4mm banana plugs.
