At a Glance
Phono Box S was one of our favorite products, it offered unrivaled sonics and versitality at a very affordable price. When we started creating Phono Box S2, its successor, it had to have exactly that but improve on sound even further. Phono Box S2 features incredible micro-details, dynamics and precision with a soundstage usually found in much more expensive products.
