"Also, 8 ohm speakers have been driven superbly
when connected to the 16 ohm tap of the 2.5K transformer."

That would load the 2a3 at 1250 ohms. You are free to like the resultant sound but just because you like it and call it "driven superbly" doesn't mean that those speakers are being driven superbly.

At 1250 ohms the load line for the 2a3 would be rotated towards the vertical and the harmonic distortion will be increased a lot. From 4.44% THD to 11% THD. "Superbly driven" is not a good description of what is really going on here. Distortion is not just a measurement. Distortion can be heard.

I think you like the sound of distortion. Your statement above indicates that you do.
