The SI-300.2d integrated amplifier is yet another milestone as Cary Audio forges deeper into the new era of sought after premium audio systems. Cary Audio is highly regarded for the rich, warm, yet detailed sound of our components. This includes both analog components and digital components, as we have become a reference standard in both. Combining Cary Audio’s analog preamplifier and power amplifier sound with our spectacular digital section is a natural evolution, and one that is stunning to both hear and see.
The SI-300.2d mates a 300 watts per channel stereo Class A/B power amplifier with analog RCA and XLR inputs to a Class A analog preamplifier gain stage. The amplifier itself is biased to run Class A for an extended portion of the power output to deliver that rich, warm, yet detailed sound Cary Audio is known for. The digital section is a chip off our reference products thereby including only the best digital circuit topology, digital to analog conversion process, and technologies like our proprietary TruBit™ Upsampling and OSO™ reclocking features. Digital inputs include; XMOS USB capable of True native DSD up to 256 and PCM/DXD up to 32 Bit / 384kHz, as well as Coaxial (2), Optical, AES/EBU, and aptX® Bluetooth inputs. What’s more, all SPDIF and Bluetooth digital sources offer 10 TruBit™ selectable upsampling or PCM to DSD conversion options. On the analog side, the SI-300.2d includes 4 analog inputs (2-balanced XLR, 2-RCA), with one each of the XLR and RCA inputs offering true Cinema Bypass features.
The powerful solid state Class AB 300 watt x 2 stereo power amplifier ensures even the most difficult of loads are tamed while delivering Cary Audio’s famous tube like sound from its solid state output devices. With the SI-300.2d the externals are also something to behold. The center mounted machined aluminum volume control is flanked by a pair of gorgeous analog “Cary Blue” VU meters to the right while the left side text display shows all source information. All this trimmed off by a handsome aluminum frame highlighting its beautiful design elements.
Additional features include: a pre/subwoofer output, coaxial and optical digital outputs, IR hand held remote, trigger out, IR sensor input, and Ethernet and Wi-Fi for controlling the SI-300.2d with free iOS and Android apps.
