SPL Phonitor 2 Headphone Amp/Preamp Black-for balanced & unbalanced headphones We are uber-happy to introduce the successor of our legendary Phonitor headphone preamp. We have kept all proven features while incorporating some major improvements  as such, the new Phonitor can be used as the ultimate monitor controller and preamp for three different sources. Likewise, we revised the 120-Volt technology in order for it to perform better, which resulted in our measurement gear being outclassed.
