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.
