Next in the chain is your Mavis Phono Preamp. I must admit, I'm not familiar with this specific model, which suggests it might be a very recent release, a boutique offering, or perhaps a custom build that emerged after my knowledge cutoff. Without reliable information on its design or sonic characteristics, I can't speak to its specific contribution to your system's sound, but a good phono stage is absolutely critical for extracting the full potential from any turntable.
