There are 5e3's and then there's really good 5e3's that sound like they're on fire and about to explode. What's the secret recipe that make some of them sound like they're really pissed off? Certain transformers with certain coupling caps with certain speakers? I've built two 5e3's so far and experimented with a lot of different caps and speakers and both of them sound good but, they don't rage like some that I've heard unless I boost the crap out of them. I'm sure some of you guys here have built some exceptional sounding 5e3's. What components did you use?
