I would leave it as is. They already use top quality parts and that is the way it is voiced. If you put in different parts, it will not sound the same.
Mods to Primaluna Evo400 preamp
Has anyone modded their Primaluna Evo400 preamp? Or a similar preamp / integrated?
I'm looking for recommendations to tweaks. Does changing the input jacks to higher quality, or swapping capacitors help?
I am enjoying this pre, and have locked into a supply of 12AU7 tubes. I don't see changing it anytime soon. So therefore, it's time to mod!
Finally... if anyone has a circuit diagram, that would be super helpful.
