My zu druid V speakers sound much better with the 8ohm taps on my prima luna HP. It's not even close.
Trying different output impedance taps with tube amps
My Antique Sound Lab Tulip 2A3 SET amp has 4, 8 and 16 ohm taps. I had been running the 8 ohm taps, and had a friend over to listen. He suggested the 4 ohm taps might be a better match for my speakers (Audio Note AN-Es). He was right, and it made a really nice improvement.
If you have multiple taps on your amp(s) and have never tried the other ones, or haven't for a while, it's worth a shot. Even if you are using the recommended or “right” ones for your speakers, you might be surprised.
