Spirito MKII Reference Stereo Preamplifier

The Viola Spirito offers a level of transparency and musicality that is truly state-of-the-art. It’s modular design uses an open architecture to give the maximum flexibility for upgrading and expansion. To ensure the greatest isolation from mains borne noise, it employs a choke input filter type power supply, housed in a separate chassis.

Spirito II Audio Design

The Spirito uses Class A discrete circuitry and is fully balanced throughout. The input impedance of the input module is unusually high at 1Mohm. This avoids the loading that can be imposed on source equipment when lower input impedance designs are used. The fully balanced topology ensures the maximum rejection of common mode noise, greatly contributing to the stunning clarity and silent backgrounds that the Spirito provides. The ability of audio equipment to reject noise is an important consideration in the increasing noisy modern domestic environment.

Simple User Interface

Discrete volume and balance controls are located on the front panel. All other unit functions are controlled by a large touch sensitive display. This allows the unit to be easily configured and controlled in stereo, multi-channel and multi-room modes. It also provides the flexibility necessary to allow other types of modules to be easily added in the future. The user can assign alpha-numeric names of their choice to each input.

Low Noise Power Supply

The Spirito’s choke input filter power supply produces far less electromagnetic interference than the capacitor input designs most often used in preamplifiers. It also places less stress on the power supply components, leading to higher reliability and longer life. In addition it completely avoids the high frequency noise that occurs when switch mode power supplies are used.

The Spirito’s choke input power supply virtually eliminates high peak ripple currents, minimizing intermodulation distortion on the power supply rails and ground returns. This further enhances the sound quality by reducing both noise and distortion.

Modular Construction

The Spirito’s main chassis has ten user accessible card slots. These are loaded from the rear of the unit and permit the Spirito to be configured to suit a wide range of applications.
