Hey guys,

I'm looking for a basic hardware passive EQ that's slightly portable for headphones, it can be simple (3-band), just something like a RC-circuit. I don't mind modifying products, and I've seen something like this very basically implemented on the cheap Bravo Audio V3 hybrid amp. I've briefly looked around to no avail, but I may be overthinking my searches :) I'll build one myself if I have to, but I'm curious as I haven't seen any product that just does this basic thing without an overly complex topology or active EQ, or even something that has tens of outputs. Just looking for something with high quality and clean components, preferably precision, low ppm resistors and quality capacitors as to not degrade the signal path. If something like this exists on the market, and is slightly portable (not like a rack mount size), let me know. If not, I'll probably just end up building one myself as it is quite an easy circuit.

Thanks in advance for any input.
