Looking around, we can all agree that both the SVT-CL and the 2 PRO are rated at 300 watts, yet they put out more than that. But how much more? I hear double all the time, and the Mesa 400+ peaks at 500 watts with (what I hear) a similar power section. But I've also heard that the SVT can easily match the 4 Pro, so that's about 4 times the RMS value. Anybody measured it, or have strong evidence of what it is?
