What is the best speaker cable for Martin Logan SL

depends on what your taste in sound is.

I have ML Summits and use Tara Labs Air 1 with good effect. I wanted to avoid a cable that was to bright but wanted good detail, dynamics and rich texture.

Best that I have found so far for my ML CLSIIAs are AZ Satori.Have used MIT 750,DNM Reson,AP Oval 9,Audio Magic Sorcerer,XLO Ref5A series 2,amongst others.The Satoris have the best resololution,crispest highs,fastest response,sound rather natural.The Oval 9s had the best bass,the Audio Magic Sorcerers were second best overall.
You might look into after market PCs,too.
