@charles1dad - there you go acting rational vs a blanket condemnation… I believe the fuse community loves to say and i paraphrase: If you haven’t listened you don’t have a valid input.
My reaction after listening twelve hours strait yesterday could have been summed up - keep trying and listening….
i don’t have dampers on the 4 tubes in my Aesthetix DAC or my Herron or Croft phono preamps because in that circuit of Jim Whites / Keith Herron / Glen Croft, they don’t help, even prove detrimental.. But as described they do benefit other components in the chain..
Although, i need to back and put the ADC damper on just the Mullard Neon in the regulator circuit…..
Best to those w open ears, minds…
