Honestly kinda surprised how good some of these mini amp setups sound nowadays.It is, and not really, other than it being one of the cheapest with a line/sub out. It also has PFFB which supposedly makes for more neutral output. Was only testing with my Pixel 9 Pro + USB-C to 3.5mm adapter (unsure where I got this from). It did sound a bit bright, but those Klipsch horn tweeters tend to be as well.
