Now I'm a little confused. I can't figure why a good power amp in back wouldn't benefit.
I just did a gig on stage going direct to mains and back through the monitor and was very happy, but if I wanted to take just an amp why not a Kemper with a built in power amp and a small speaker system or cab. I plan on going FRFR and have a design I'm working through with someone. I'm sure my speaker system will want a good amount of power and I'd like to see the Kemper, if possible, receive something that can put out. It'd be nice to have just a Kemper and cab vs Kemper(not rack mountable), Power amp(these often having a rack-mount profile), and my speaker system. But if its beneficial to more people to have a low W internal amp those like me can look to powered speakers.
