Sunnyjim, the impedance curve of your speakers, as shown near the end of this review, is much more benign than most, being fairly flat, at about 5 ohms through much of the spectrum, and with phase angles that are not highly capacitive at any frequency. I suggest that you research posts by owners of the same or similar speakers to see what cables they are using. The fact that most other speakers do not have impedance characteristics that are similarly easy to drive, and may also differ significantly from the 5 ohm nominal value, suggests that recommendations based on experiences with other speakers stand a good chance of not being applicable, IMO.
