Discussion about the Korg PolySix synthesizer

Sorry for this dull question but I remember I once read on this forum that changing some old capacitors for better new ones could increase the overall quality of the audio signal.

I've also bookmarked a french article about the impact of passive components on sound :

About Jean Higara (in english) :

Of course this article is aiming the audiophile community (Hi-Fi) but I wonder if we could adapt their advice to improve our beloved P6.

I don't have a clear (not to say any) idea of the complete audio signal path in the Polysix and which components are involved in this process.

The question is definitley dull : I don't even know if those improvements would be noticeable for "normal" ears.
