One consideration I thought I’d mention. When you are comparing taps, remember that the as you go from 8, to 4, to 2 ohms, the gain of the amp is dropping 3 dB each tap change. So you have to increase your preamp’s gain by an equal amount to create a fair comparison.
The easiest way to do this is with a test tone or pink noise and an spl meter placed close to one speaker.
If you don’t do this, the higher impedance taps will always sound better because they will be louder.
