Know before you buy
The dual-box construction physically separates the power supply from the sensitive control circuitry. This isolation prevents electromagnetic interference and noise from contaminating the audio signal, resulting in a cleaner, more transparent sound.
The Unistage design amplifies the audio signal only once, which minimizes the number of components the signal must pass through. This approach preserves the integrity of the original recording, ensuring superior clarity and a more engaging soundstage.
No, the REX 3 is a fully balanced design and exclusively uses XLR connections for all inputs and outputs. You will need to ensure your source components and power amplifiers are compatible with balanced XLR cabling.
Instead of using a traditional mechanical potentiometer that can degrade over time, the REX 3 uses a precise electronic shunt attenuator. This allows for fine 0.5dB adjustments while maintaining signal purity and channel balance.
The 18 tubes are utilized to achieve the REX 3's signature transparency and musicality. By distributing these tubes across the control and power modules, the system maintains high-fidelity performance and exceptional dynamic range.
Yes, the preamplifier features a customizable user interface that allows you to personalize settings to match your specific system configuration and listening preferences. This ensures the unit integrates seamlessly into your existing audio setup.
