Dennis’ amps use very high quality parts but don’t stray into the ultra-fi zone. Nelson’s designs use high quality parts that are still fairly inexpensive (most of the cost of DIY versions of designs is in the metalwork).

My stock Mundorf/Jantzen caps of of much better quality than any other tube amp I have owned (my 421A amp uses NOS Jensen PIO, so they don’t count, and my old 45 SET was direct coupled), and it is likely I will only be adjusting the flavor of the sound rather than its essential character.

You simply need to experiment and trust your ears.
