First off, would I even need a headphone amp for the DT990's if I have a mixer? And if so, would the Focusrite Saffire 6 get the job done? I've heard insanely great reviews about both the 990's and the Saffire 6, especially on DOA. My budget for everything total is $1,400-1,600. Now, to the products themselves.
I've been leaning towards Adam A5X monitors, simply because I heard a couple of good reviews on them, and they are within budget. I know almost nothing about studio monitors, so any advice and suggestion(s) is welcome. With a mixer, I've found the Yamaha MG124C's and the Mackie 1202-VLZ3's to be good choices, as both are definitely within budget along with the monitors (and headphone amp). Again, I'm open to ANY good, worthwhile suggestions, as I'm moving rooms in my household, and feel like with a fresh room, I should get some fresh gear. Quality gear really. Thanks in advance.
