Good luck, iQEM!
I added some gallery-type links to the OP. I finished another diyMod for someone recently, and it feels good to be able to hear its music flowing into my ears.
Further report on the BG/VitQ situation. I tried VitQs and found it to have a nice sound. My test methodology was to pass reference tracks through an inattentive mind and see what differences my mind could pick up. The reasoning behind this type of test is that the mind filters out that which remains relatively constant; think morning routines and "waking up on the wrong side of bed." If something changes, your mind will be all, "What^ mate?" Through some quieter passages in Explosions in the Sky's latest album "All of a Sudden I Miss Everyone," I picked up on an egg keeping the beat during "The Birth and Death of the Day," something that usually wasn't as distinct and clear through the BGs. FR balance seemed quite similar to the BGs as well. Then I tried VitQs bypassed with BGs/BGs bypassed with VitQs. I heard absolutely no difference with this setup. I could hear a very faint click every time I went from bypassed to unbypassed and back, but beyond that there wasn't a real noticeable difference. As always, YMMV. I did like the VitQs as a final result, but I probably won't be using it for some time. I have to try it in my MAX next, but I need some time to acclimatize to its sound before the swap (see methodology reasoning above).
