Goetz is a good choice

With OTLs, I have found that speaker cables with low characteristic impedance work best. Among such cables is the Goertz ribbon type, or most any ribbon type cable. I use Goertz silver ribbons. Going silver might represent an upgrade from the copper, depending upon your personal taste. Other cables with low-ish characteristic impedance are MITs with termination boxes or Transparent with termination boxes. (The boxes usually add capacitance.) IMO, stay away from Nordost cables which tend to go for low capacitance, which usually results in very high characteristic impedance. I've tried two Nordost types with my Atma amps and both sounded terrible.

Characteristic Z = sq rt (L/C). So, if you can find out inductance and capacitance per foot, you can calculate CZ. However, the value of CZ is independent of cable length.
