I was replying to the OP, it seems I'm out of context.Ianidx hasn't mentioned an AVR from what I can see, he has only mentioned he has a stereo amp and is looking to add EQ. I have an AVR and a stereo setup which is 2.1 with PEQ/Dirac in my living room, plus a pure stereo setup in another room. I wouldn't assume everyone is looking for the same setup, though, some people are not interest in multichannel.
"I have an Audiolab 6000A integrated amp which i'm using for 2 purposes; 1 as a power amplifier for my front channel speakers - the 6000A is connected via the pre-out of my Denon X3700H AVR - this function is working flawlessly. I also use the 6000A as an integrated amp for stereo music via the WiiM mini streamer. The speakers in question are the Klipsch RP-6000F."
