Speaker cable length


I have Cary tube amps and Harbeth speakers and I am kind of limited as to the placement of my components in my listening room. The optimum positioning for best sound would require a 27 foot speaker cable on one side and an 18 foot cable on the opposite side. Are these runs to long and could they harm my equipment or somehow lower sound quality?

I think these are too long. I put my power amp between the 2 speakers and run a 6 feet length of speaker wire to the speakers. The interconnect from my preamp to amp is about 16 feet...works fine. In any case, I would have equal lengths of wire for both speakers.
I also have a similar set up, but keep shorter speaker cables (6)', amp resides between speakers, and running longer ICs( 15') from amp to source.
Hope this helps.
Problem is that between where my speakers should be positioned for best listening is a large floor to ceiling window so putting my amp between speakers wouldn't work.
Depends on the cables and amp.

At CES in January 2007, AJ Conti of Basis Audio ran a pair of speakers with his cables. One speaker was wired with a 6' pair and the other speaker was wired with a 75' pair.

Not a single listener could discern the difference.

Go figure.
