I have noticed unloading (higher) plate impedance from manufactures recommended specifications makes for lower distortion. What I find shocking is I hear distortion when many others DO NOT hear it. And, distortion is unpleasent. Anyways, the quality of the output transformer is more important than the 3.5K vs 5K impedance. I will have both high quality audio transformers and the 5K impedance. 2A3s are most linear at 250 volts plate.
