Keep in mind that I can make you 60 - 70 different amps, completely customizing for every customers system and budget !!!!
However, in short terms the SE option that you are referring to has:
- all Vishay Dale military spec resistors
- all silver micas
- Nichicon gold and Nichicon Muse caps
- Bridge upgrade
Hand in hand with this upgrade should always be the Groneberg TS Premium topline output cable upgrade as well.....
Makes a nice improvement, for sure....
