I can agree with you on that Kurt. The best resistors, caps etc.
Unfortuneately, their are some other problems with some of the older tubes. The Gp (grid to plate) capacitance is twice or more that of IDTs. IDTs offer lower distortion, less drive, fewer stages needed or more effectively utilizing that stage if used, fewer parts in the overall design, fewer solder connections. I could go on but the overall superiority appears clear. And if each part does distort like we both agree, the fewer stages and accompanied parts means less non measurable distortions. For instance how do you measure "sheen" in music. I think one of the very best designs is DC coupled where you can get rid of a coupling cap. and bypass cathode resistor cap. Even the best are deficient. Good conversation.
