It doesn’t get any cleaner than the UAD Elysia Alpha EQ, or any flatter of a frequency response. The hardware version costs over $10k, of which $1.75 must have been devoted to the interface.
Seriously, we can’t do any better than this? And it is really awkward using it on the computer screen. Still, it’s about as good sonically as you can get if you are looking for the clearest possible sound, so screw UX.
