No you think lower THD sounds worse.

You hear it as sounding worse for what ever reason. But I keep saying this. The job of the amplifier is to preserve the signal with the sole exception of gain. Anything else added is distortion and therefore a defect.

I don't see why this is so hard to understand. If you want true to the source reproduction, you can't add or subtract anything from the signal except simple gain. And furthermore that gain must be absolutely linear across the entire frequency range. Not much of a problem in audio amplifiers, but a serious problem in earlier video and RF amplifiers which I have a great deal of design experience. Video OPAMPS were a godsend for this problem. Look up differential phase and gain. You won't ever hear that discussed in audio circles.

Do you know the history of the 300B. The reason it is a very low distortion tube? That's got nothing to do with HiFi audio. It had to do with RF frequency multiplexing in the early telephone system. Distortion in a frequency multiplexed signal can make it completely unusable.
