And it is worth trying the different taps on your tube amp to see what works best in your system. My bi-wired Von Schweikert VR-4 Gen IIs are 7 ohm nominal impdeance. But since the bass module is 4 ohm, the speakers sounded much better out of my Rogue Stereo 90's 4 ohm tap.
Best Speaker Impedence for Tube Amplifiers
I have read conflicting information regarding the best speaker nominal impedence match for tube amplifiers. I know the actual impedence can vary, but all things being equal does a tube amp have an easier time driving a 6 ohm or 8 ohm speaker? For this question, assume speaker sensitivity is about the same.
