Dear yldzumt,
when I started my journey with the Kemper, I also struggled quite a bit to find the right profiles for my personal taste and needs. Reading your post today reminded me a lot of that experience, so I thought I might share a few thoughts that could perhaps help a little.
I listened to two of your wave files and, to my ears, they sound absolutely fine and seem to represent the profiles in the pack quite accurately. I should mention though that I only own a Version 1 unit, so I was not listening in full HD mode — whatever influence that may or may not have on the final sound.
That said, my personal impression is that the profiles in this particular pack do not fully showcase what the Kemper is capable of overall. But of course, that is highly subjective and largely comes down to individual taste. One thing I learned over time is that different profile makers often pursue very different ideas of what a great guitar tone should sound like. Some highly regarded commercial profilers simply have a tonal philosophy that does not necessarily match my own preferences — and that is perfectly fine.
I completely understand your wish to get a quick “return on investment” in terms of satisfaction and usability. At the same time, I think one of the beautiful aspects of the KPA universe is exactly this diversity. Everyone can create, share, and use the sounds they personally love. And even if a profile pack comes from a very well-known company, that still does not automatically mean it will fit your ears or your playing style.
If you have the time, I would really recommend exploring the Rig Exchange and trying random profiles from different creators. Over the years I came across countless profiles where my first reaction was “what on earth is this?” — yet clearly the authors loved those sounds enough to share them with others. And that is actually part of the charm: not every profile will appeal to everyone, and that is completely okay.
Just my personal thoughts and experiences of course.
