I wouldn’t waste the money on “better” connectors. I’m sure they use decent quality pieces on this. You will not notice any difference. The only time I would replace connectors is if they stop providing a good contact. Keep ‘em clean and you’ll be fine.
As stereo5 mentioned, changing parts could alter the sound beyond what the designer intended.
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.
