I have a similar set up problem with a long distance between my electronics and speakers. Both Ric of Argent Audio and Robert or Ridge Street Audio suggested I try the Alphacore Goertz wire which is designed to work for long runs.
I ordered a pair of the M2 and tested it out. While not the final word in sonic resolution, it sounded excellent, far better than the long runs of DH Labs Q10 I was using. Good soundstaging, highs and lows, just not the ultimate in detail that could be gotten wth speaker wires like TG Audio, Argent Audio, or Ridge Street, none of which are available or affordable in long lengths.
I liked the AlphaCore wire. The flat copper or silver is attractive, but looked to easy to damage. So I exchanged it for the Python version, same wire in a round casing. After much research, the www.alphacore.com wire was the best solution I found for long runs.
