Kemper has dedicated (really good) Headphone output in the front, so you don't have to use line level outputs in the back. It's perfectly OK to use KPA only with headphones. You can buy powered speaker later.
Ok, thanks. I was hoping for this. I'd have to wait about 5 weeks after getting it otherwise, so thanks for the quick(ish) answer. I was planning on getting a Yamaha HS-8 active moniter because some guy on here says he uses a pair of those with his Kemper and he said they sound good with it. Anyway, thanks again and have a good day/night
