A quick search on the big box web site and I find dozens of light class D power amps in the $399-$499 range. Most are 350-500 watts. My question is do we consider most of these gig worthy? There's a small sample of these available locally for me to try out, I think just the Ampeg and Fender at GC. So, should I buy just what's available, that I can try out, or go out on a limb and order something? I'm abit concerned that some of these might not be so rugged. Your experiences would be appreciated.
