Hello everyone, and welcome back to another video review. I always aim to be straightforward with you, and that’s a principle I’ll continue to uphold. As I mentioned in my Aune S9C video, I’m not a fan of manufacturers that flood the market with numerous product releases each year. It seems SMSL Audio falls into that category.
