I suggest, if you have not already, perhaps play with a really good software EQ, it's been awhile since I did software EQ, but I know there is an excellent parametric plugin available for foobar. This may help you decide if a better hardware EQ is worth your time. Really, there's nothing wrong with software EQ, it's just a pain in the ass. Often times requiring workarounds and poor software, I've looked at all the options and im impressed with none, from a usability standpoint. (on windows) I tried APO, but it was buggy, clippy, and did not bypass the windows mixer, which i can ABX. Qubuz works exceptionally well with the ADI2. Tidal not so much, if your into non 44.1 content. Mostly because Quboz supports ASIO, which is required for ADI to auto-switch bitrate.
