Hello romney80,
Naim amplifiers, such as the Nova, feature a unique output impedance that can cause performance issues when connecting standard speaker wire directly to it’s output terminals. REL has two solutions for connecting High Level to the Naim Nova:
1. Connect the S/5 directly to your speakers, which will likely involve stripping back the wire jacket in order to reach both your left and right speakers.
2. REL has a version of the Baseline Blue upgraded high level cable that is specially designed to account for the unique output impedance of Naim amplifiers. Along with this specialty circuit, the Naim Baseline Blue also features stacking banana plugs that allow you to connect both the high level cable and your main speaker wire to the Nova’s recessed banana ports. In our experience using stacking banana plugs does not result in any signal transmission issues.
Alternatively, since you are using a single subwoofer you could connect the S/5's Low Level input to the designated subwoofer output on the back of the Naim Nova.
