Each of these changes can make a dramatic influence on sound! ~~~~~~~~~~
I know some audiophiles are not won over on swaping parts. = A cap is a cap is a cap...
I am a believer.
I prefer Takman Rey metal vs any and all carbon **smoothhhh* resistors. Caps, Mundorf SESGO or Silvergold EVO, whatever I can afford.
Tubes also make a gain, Teles in the pre, and have yet to roll these stock Psvane. My tech thinks there is not much to gain swaping out power tubes...we will see, that experiement waits til mid summer.
