Mark Levinson HF-2.5C speaker wire

I just moved to Prescott,AZ and a new house. I am trying to improve the poor acoustics and sound in my living room by putting carpet over the wood laminate flooring & moving the speakers so they play into the length of the room rather than across the width of the room. This means that I have to increase the length of the wire used for the left speaker. Unfortunately the Acarian Systems Alon 4 speakers are tri wired. Right now the system uses the wires listed above. I would like to find the same wire in used condition if possible. The option would be to just wire the entire system in14 guage Monster cable. I would need about 141 feet. I wonder if I did the latter would I hear any difference in the sound by using an inferior wire?
