The Virtus I4S is a foundation line integrated amplifier featuring a built-in phono stage and headphone output.
Product features
- Refined central knob with an integrated 1.8-inch display combines a dual-bearing design, ultra-smooth rotation, and innovative CCD-based position sensing for precise, tactile control.
- Fully discrete dual-mono circuit technology.
- Discrete built-in headphone amplifier with top-notch parameters, sufficient to power the vast majority of high-quality headphones.
- Finest discrete phono amplifier supporting MM/MC with gain adjustment, a wide range of capacitance and impedance settings via front display.
- Exceptional 40 000 µF per-channel filtering capacity in the power supply allows the Virtus I4S to deliver deep, dynamic bass with precision and control.
- Low-distortion variable RCA output designed to support subwoofers or additional power amplifiers with a clean, precise signal.
- Low output impedance improves the overall amplifier's sonic performance thanks to the use of oversized output transistors and an unconventional circuit design.
- The Virtus I4S adopts some proven concepts and technologies from the reference line Virtus S1S, such as an "Error Correction Technology", which is a specialized local feedback circuit to linearize the amplifier output stage. This technology helps to prevent transient distortion from occurring in the first place, rather than relying on overall feedback to suppress it. Ideally, this results in a weaker overall feedback circuit compared to one without error correction.
- The display offers two color theme options, allowing the user to select their preferred interface appearance.
- Virtus I4S supports wireless firmware update.
