Thanks to everyone who has responded so far.
It looks like the best option is to sell the HT cable OR possibly run the risk of a botch job on the cable by a garage slicer and re-terminator.
I have a deal on hold with Grover Huffman cable for his new model of speaker cable. I bought the Z series?) a few years back and was impressed with it, but I broke off one of the bare wire leads at the stem
GH claims bare wire is the best connector However fiddling behind a component rack is bad for the back (Rhyme not intended).
Do banana plugs or spades seriously degrade sound quality of speaker cable?? Or, is that just an audiophile's "old wives tale" ??
