I was planning on keeping my amp, but I came across 2 really good deals and I'm not sure which I should jump on... I can buy a Us Amps Merlin MD3D (rated at 2k) or a Crunch Groundpounder 3000 Pro (rated at 3k). The price is $200 for each. Which would you guys get? I know crunch is usually looked at as a cheap brand, but I've heard good things about the GP series.
