Know before you buy
By operating at a lower voltage than traditional tube preamps, the Rhythm 1.4 reduces thermal stress on the internal components. This design choice significantly extends the lifespan of the tubes while maintaining high-fidelity performance.
The ultra-low 75-ohm output impedance is designed for maximum compatibility. It allows the preamp to drive almost any power amplifier—solid-state or tube—without signal degradation or impedance mismatching.
The patented GreenForce™ power supply acts like a battery-powered source, providing a clean, stable current to the amplification circuit. This results in an exceptionally quiet noise floor and improved sonic purity compared to standard power supply designs.
Yes, the solid-brass bottom panel adds mass and rigidity to the chassis, which helps dampen mechanical vibrations. This contributes to a more holographic soundstage and greater depth in the audio presentation.
Yes, the Rhythm 1.4 features a standard IEC input. This allows you to experiment with different power cords to fine-tune the system's performance to your preference.
The preamp is well-equipped for complex systems, offering three RCA inputs and two balanced XLR inputs. For outputs, you have two sets of RCA and two sets of balanced XLR connections, providing plenty of flexibility for bi-amping or multi-component setups.
