Yeah, don't get me wrong im a believer in EQ. But i've yet to find a system wide solution that just works without handicaps, particularly bypassing the windows mixer. Equalizer APO is good but it gets mixed, and the WASAPI mode for true fi did not work with my DAC, i just got horrible distortion. There's also other issues of software solutions, like random bugs, things like not working with games, or youtube, or your favorite streaming app... software EQ's just a pain in the ass. Especially for those who run both headphones and speakers and need independent EQ settings for both. I use HD650's and JBL LSR305's and both have their own equalization needs, my room has a sizable bass bump that needs to be delt with.. software EQ again is a big let-down. I've recently purchased a RME ADI-2 and hope to resolve all my woe's with a solid hardware based EQ solution. My primary source of music is Tidal, now that is a real pain in the ass to get any kind of EQ working with. It's really ridiculous, the hoops one must jump though. I've been told you can use Jriver but that's a paid piece of software and I've yet to try it, regardless it's some convoluted setup of routing Tidal to Jriver then applying EQ sourced from a plugin that allows the use of VST software.. what a pain in the ass.
I'll take my EQ before or after windows, were I can truly apply systemwide, source independent EQ. And by the way , the windows mixer does seriously handicap quality. I can easily hear it, so much so that im confident I could Double blind it.
