I would HIGHLY suggest using a Zobel network when using even a reasonable length run of any of the Goertz speaker cables. Due to their high capacitance / low inductance design, some amplifiers of wide bandwidth design can oscillate and overheat. Besides having the potential to due possible damage to the amp, the sound will not be as clean, clear or focused as it should be either. Goertz will supply these at no charge for use with their cables. Sean >
