hARt Lab Tune Two preamplifier with Streamer, DAC and Phono inputs and headphone output.

Tune Two takes your listening experience to a whole new level. Not only does it use the best audio attenuation technology, it also amplifies the audio signal to drive any combination of cables and power amplifiers. It also provides all modern conveniences with multiple options for digital and analog playback.

It is designed around a class A amplification stage with vacuum tubes and a selection of components, not only according to the performance of each one, but also to match their sonic character. The result is a preamp that speaks the truth and reveals the best elements of music, regardless of your preferences. With great looks and simplified control using any modern web browser, this preamp will give you a true audio experience.

Features

• Built-in DAC with coaxial and optical inputs, where the signal is converted only in terms of sample rate (bit-perfect) and re-clocked for optimal performance.
• High-drive headphone amplifier. Tube-MOSFET, Class-A hybrid design for great sound.
• Fully configurable Class-A phono stage for MM and MC heads. Discrete active circuit design for excellent accuracy.
• Plenty of analog and digital inputs for maximum comfort and functionality.
• Integrated media player with wireless and ethernet connection, functions and settings for digital audio and USB ports for external HDD/USB-stick.
• Amorphous fiberboard chassis reduces unwanted vibration and mechanical noise feedback, resulting in a lower noise level and elimination of interference.
• MlCoat high perfection luxury paint process. Highly refined multiple layers of paint, offer a durable and smooth surface.
• Removable sides for a personalized look by changing color and/or material.
• The combination of manufacturing methods, subtractive (CNC) and additive (3d-printing) manufacturing, together with a mixture of materials (wood, metal, plastic, rubber), gives a stunning appearance and promotes unrivaled music reproduction.
• The user can choose any of the 15 available colors for the front lighting, matching the aesthetics of their environment and reduce them to 3 levels or even turn them off completely.
• Simple Unified Management. Tune Two is controlled from any modern web browser running on any device such as smartphone, tablet, computer, etc.
• Standard infrared remote control for main functions.

Technology

• Amplification of a Class-A stage with 2x CV181 (or equivalent) vacuum tubes, photodiode biased and without any feedback, provides excellent linearity and superior sound output. Optionally combined with a Class-A buffer it forms a hybrid arrangement, which enhances driving capabilities without compromise, for any power amplifier and interconnect cables.
• Alternate direct vacuum tube output for clean signal and ultimate performance.
• VAcc battery emulator with 12 individual, fully separated power supplies for digital and analog audio, and digital control.
• Dual Mono architecture with a single common GStar ground point for full protection against mains noise and ground loops.
• Attenuator (volume control) SLadd based on relais with 64 steps of 1 dB provides constant input impedance and achieves zero tracking errors and interactions between left and right channels, which results in an excellent soundstage.
• Acrylic back panel with local source switching for minimal audio signal path.
• Suspended power supply effectively decouples power transformers from sensitive audio circuits.
• FloatO built-in absorbent mounts for a quieter background and extended sound dimension.
