I also met Koolpep who was really kind enough to show me a lot of his stuff including amps, iems and full sized headphones and let me try it all out patiently. It was pretty much a sound signature galore and I enjoyed every bit of it. I'm in the same boat as you, don't have high end equipment but it's always fun to try new things before upgrades. What equipment do you own? I posted my list a couple of pages back.
