Kimber 4tc good enough?

This doesn't sound like a great combination.  Did the dealer sell you the Kimber?  Or is it left over from a previous iteration of your system?  What are you trying to achieve?  I would expect that triple combo to be on the forward/tilted up side of neutral.  There are many threads about single versus bi-wiring and about different brands of SC.  Your observation of what the dealer himself is using is pretty telling, I would say.

I bought the 4tc over 30 years ago. I don't have the cable the dealer used in the demo I just find it cutious that he would say 'cables don't matter' while himself use some apparently serious stuff.

When I bought a pair of salon 2's(used) I had lightweight bass and some suggestions were to biwire or replace the 4tc completely with heavier gauge. I would like to know if a biwire run of 4tc would provide the speakers with more watts/current than the single run I use now?

I bought a  4TC for bi-wring , it is just two 7 feet 4tc 's cables coming to gotogether at the bananna .   Those 8 pieces of cable  will bring a lot more .
And it sounds very good  running into a Quad  S5 which is a speaker that needs some juice.  150W Belles is the amp.
Wire was bought from Audio Advisor .
