and I decided to look at Nelsons commercial product well reviewed.
That means the classic circuit but the caps Nelson recommends in the B1 pdf himself
- the Vishay metallized polyester 1uF caps for the input
- the Axon 10uF for the output
This combination was the only one that had magic to my ears.
They but the B1 a bit on the dark side, blow up the stage….so if your system is already on the dark side this might be too much, if not highly recommended.
for me the most convincing example that caps form sometimes a better sound.
and these caps are cheap!
and the First Wtt is......a really First Class PSS Idea
