As always, Kevin Carter stands behind his products. He provides excellent support and prompt response to service needs. Very happy with my decision to go with his Maxxed Out phono preamp!

The premium mc phono step-up kit I recently purchased exceeded my expectations. I purchased the kit to reduce the gain on a Pass Labs XP-15 phono preamp to 46db and achieve a gain of 64db using the 18db gain setting with the K&K step-up. By using the Lundahl LL1931 step-up transformers in the step-up kit, I was hoping to reduce the noise floor from the active 66db gain stage in the XP-15. The Pass Labs XP-15 is a very musical phono preamp and installing the K&K step-up not only reduced the noise level to almost a completely black background, it also increased the musicality of my system. The step-up kit is an incredibly good value and the quality of the components in the kit are great. Thanks Kevin.
