WADIA di122 & a315

WADIA di122 & a315
Konwerter DSD/DXD oraz 150-watowa integra to dwa nowe produkty marki należącej do tej samej grupy kapitałowej, która zarządza McIntoshem, Sonus faberem, Sumiko i Audio Research. Cena dekodera - 1500 funtów. Podobnie będzie chyba wyceniona integra. W kolejce do sprzedaży czekają też już monobloki a340 oraz końcówki a102

The Wadia di122 two-channel digital audio decoder integrates Wadia’s superior technical performance with our new Series 1 mini industrial design. Its sleek, modern aesthetic is compact in size to fit in virtually any location while complementing any surrounding.

It has two coaxial and two optical inputs that accept up to 24-bit/192kHz signals; a USB input accepts up to 32-bit signals and supports DSD64, DSD128, DXD 352.8kHz and DXD 384kHz. This vast array of inputs and supported formats allows music from an abundance of digital sources to be reproduced with the extreme precision and elegance expected from Wadia.

The truly exceptional sound quality is facilitated by both balanced and unbalanced variable analog audio outputs, offering premium noise rejection for optimal performance. The Wadia di122 also features a high powered headphone output, making it versatile choice for any listening experience.

The Wadia a315 digital stereo amplifier provides 150 watts per channel at 8 ohms or 250 watts per channel at 4 ohms. It shares the same sleek, modern industrial design as the 321 decoding computer, making it a perfect amp to use with the 321. Both will blend nicely with virtually any room styling.

The a315 features some of the latest technology from Wadia. Frequency Switching Transmission™ (FST) is an adaptive modulation design in the amplifier circuitry that assures full output power is delivered over the entire audio spectrum. Signal Surveyor™ monitors the output signal and stops amplification if unsafe levels of DC voltage are detected, thus protecting your speakers.

Both balanced and unbalanced inputs are available for connecting your other system components. Specially designed 5-way binding posts will securely hold your speaker wire; they are designed for easy finger tightening and come with a special tool if even more snug connections are desired. A trigger input and output makes it simple to control the power state of your entire system when the a315 is turned on/off.
