Hi all!!! I am thinking to get a power amp for my Ampeg SVP-BSP Preamp. Something not heavy in weight, and dont break my budget I was looking into QSC PLX1202, Peavey CS800 or higher. Crown look expensive, but anyone with feedback about this one please. Which one of these are beter suited for instrument amplification? What features I need to look into when I shopping these ? The PLX1202 look good to me. What about the type and calss of the amp? A, B, AB, which one is better for instrument amplification? thanks!!
