Speaker Cable Compatibility with Amplifier and Speaker
I have heard that it is most important to match speaker cables with the Amplifier being used; more so than the speaker. I plan to connect a Krell Evo 302 to a Harbeth 30.2. I would appreciate responses from anyone who is familiar with the science of selecting a compatible speaker cable for this equipment.
