I VERY STRONGLY recommend Sonarworks SoundID software and calibration microphone (of course, do some treatment of your room first if possible).
I use this with Adam A7V monitors I recently purchased. Doing the calibration measures the acoustics of your room. It discovers whether your room itself is hyping (or under-hyping) a particular part(s) of the frequency spectrum. I found, like a lot of people, that my room was hyping the lows and low mids a bit. Made perfect sense to me. A lot of IRs and presets made by others had always seemed too thick and muddy, and that's the reason why.
The Adam A7Vs have the advantage of being hooked up to the computer and the Sonarworks calibration profile can be sent to the speakers to "bake" it in. You then can flip from the Sonarworks profile to the stock options at the click of a mouse. Very handy!
So much easier to get good tones now that I know that what I'm hearing is balanced. Wish I had something like it years ago. Would have saved me hours of frustration.
