If you go Mac try the 2ohm taps. The impedance is pretty low at 1.6 ohms. Similar to the dip on my old theils and the 2 ohm tap really helped soften the highs.
also keep in mind if you use the 2ohm taps you might want the model up to get more power as it will lower the output by a 1/3rd I think. Don’t quote me on that. I would have to look it up.
