I wasn't sure exactly where to post this so feel free to move it if need be.
I know this has come up before, but there are constant posts of new users wondering wtf is going on with their tone.
I have been an owner of a Kemper for a few years now. When I first got it, I was running it into a Crown XLS1000 into some fairly inexpensive P.A. speakers. It sounded good and a much needed upgrade from my HD500. After a month or so I had gone through tons of profiles and found a lot that I liked. But...I wasn't getting the air moving like a real amp.
So...I bought a Bose L1. It was a HUGE jump in tone. It finally was moving air and giving a much more realistic experience. But...I was having to boost the highs in almost every profile. I still felt I wasn't getting the full experience of the Kemper. After about a year, I decided to try something different.
I bought a Yamaha DXR10. As much as I wouldn't like to admit it, the DXR blew the "twice the price" Bose away. It finally feels exactly like a big cab moving air when it's supposed to and when you load up a profile of a small amp, it fucking sounds like a small amp. I'm really impressed with the Yamaha.
Of course this doesn't prove I found the perfect setup. I just wanted people, especially newer users to understand it's not just the Profiler, the whole setup decides what you hear. No matter how awesome the signal coming out of the Kemper is, if it's going through shit, it wills sound like just a little better shit.
