As a mastering engineer, my last project was a metal band out of Denver. Not usually my thing, but I studied up by watching the documentary, "Metal" - wow! There's a lot to the genre. I saturated lots of tape and tubes, and had a happy customer. Anyway, I don't monitor using Klipsch in my reference system, as I sit rather close. When finished with any project however, I listen to it in my car (stock audio system), then let it run wild upstairs on a Heresy III/Paradigm 18in. servo sub/Outlaw 1050 rcvr system. The Outlaw is no longer made, but is representative of a "typical" , modest HT receiver these days. With care setting up the sub, the HIII's will be killer! And here's a tip for you recordists out there: if you add any reverb or effects, add just over 40msec of pre-delay. It will trigger your ProLogic circuit and give you some nice surround. Have fun!
