It's obvious the current design trend is for small and powerful, and it's really a great exhibition of technology. I can only imagine what the next few years hold for gear. BUT, I've been up-sizing ever since I got a car big enough to carry stuff. I have an 810 on the way. My normal rock rig will be my head and the 810. But I still want to go bigger after that, haha. For doom and experimental stuff, I want to get a nice 300 watt tube head (maybe old Sunn 300t, Orange AD200b, or a Mesa 400+) and run it at 2 ohms through 2 215s. Throw a Y cable and run both rigs at once... I think it could do intestinal damage. I should have never found Sunn o))). I can justify any amount of gear or volume by just saying that they have more gear and are louder and making a living from it, haha.
