While @mbz makes some fine points, one thing to consider is the whole audio chain, from source to speaker. Many people specifically “remove” the tone controls from the audio path to get fewer components, traces, resistors, etc out of coloring the sound or degrading it in some way, noise to be one.
While that overall idea is not in play here since you want to add an EQ into the signal path, IMO it would be wise to keep the noise profile to a bare minimum. And that would mean film or LL caps in the audio path.
Let’s just say your amp/receiver/integrated has a signal to noise ratio of 95dB, and you’re running a CD source with S/N of 105dB. You have just increased the noise level over that of listening to the CD through headphones, if the player even has a jack. Now, you add an EQ to the mix. If it has a S/N figure higher than the amp's 95dB, you SHOULDN'T hear any EXTRA noise, i.e. only how you contour the sound with the sliders. If however, the EQ only has a 90dB S/N, you've just added even more noise to your audio signal, which will muddy the sound further. I’ll look further at the scat and list the audio path only caps, but you should be able to follow the grey arrows and see which ones are directly in the audio signal.
