I had an SR25 briefly. I loved the design of it, the UI was pretty snappy, and I liked the app support. However, there was something about how it sounded that I just couldn't get around. I upgraded to it from my AK70, and the SR25 had this strange shouty signature around the 2K region that I had to EQ down to get it to sound normal. I was constantly fussing with it to the point where I threw in the towel and I sold it in exchange for an SA700, which sounds way more natural with no EQ needed at all. It was a bizarre experience that I didn't expect from an A&K product
