Both the Muffsy Phono Preamp and the Muffsy Hifi Dual Power Supply were both quarterfinalists in the Hackaday Prize 2015 contest.
In addition to that, the Muffsy Phono Preamp won one of the weekly prizes for using Texas Instruments parts, and was awarded TV-B-Gone kit.
The Muffsy Hifi Dual Power Supply was awarded a Stickvise for solving a community problem. The problem solved was of course that you don't need to work with mains power when using the Muffsy Hifi PSU.
