Musical Fidelity X-Tube Tube Output Buffer
The Musical Fidelity X-Tube is a tube output buffer designed to add warmth and refinement to any audio system. It functions as a simple, elegant component that sits between your source and amplifier, conditioning the signal by passing it through a vacuum tube circuit. This process enriches the sound with even-order harmonics, providing a subtle warmth and body that many find more engaging and musical, especially with digital sources. The X-Tube also acts as an impedance-matching stage, presenting a high input impedance and low output impedance for a cleaner electrical handoff between components. This modern successor to the popular X-10D features two 6922/E88CC triode tubes running in pure Class A within a redesigned X-profile aluminum chassis.
