Cary Audio SI-300.2d

Cary Audio
Powerful integrated amplifier with a built-in DAC and upsampling capability. Crafted entirely in the USA.

The SI-300.2d is a Class A/B amplifier boasting 300 watts per channel, complete with analog RCA and XLR inputs and an analog preamplifier section. On the digital front, it employs the same chip found in our top-of-the-line digital products, with a digital circuit topology expertly optimized for digital-to-analog conversion. It also features our exclusive Cary TruBit© Upsampling technology. This unit provides you with four line-level inputs, comprising two balanced XLR and two RCA connections, along with Cinema Bypass, XMOS USB, two coaxial, optical, AES/EBU, and aptX® Bluetooth inputs.

For any sources connected via SPDIF and Bluetooth, you have the option to upsample to various frequencies, including 44.1, 48, 88.2, 96, 176.4, 192, 384, and even 768 kHz. XMOS USB supports sampling rates up to 32-bit/384 kHz, as well as DSD 64 and 128. The robust 300-watt transistor amplifier stage can handle the most demanding musical challenges while retaining the signature warm sound quality associated with Cary Audio. Additionally, a pair of stylish blue arrow indicators not only serve a functional purpose but also lend a unique charm to the amplifier, with the volume control positioned in the center between them.

Beyond the mentioned inputs, the SI-300.2d offers a wide array of connectivity options, including preamplifier/subwoofer output, coaxial and optical digital outputs, an IR port for remote control, trigger output, IR sensor input, Ethernet, and Wi-Fi for seamless control via free iOS and Android apps.
