McIntosh Laboratory has launched the new D150 digital preamp — a flexible DSD- and DXD-compatible digital preamp. McIntosh_DI50_digital _preamp

The new D150 has been designed to offer flexibility when adding digital source components to an audio system and supports many of the latest digital audio formats. With its five digital inputs (2x coaxial, 2x optical and 1x USB), plus balanced and unbalanced connections for both variable and fixed volume audio outputs, the D150 is suited to exploiting today’s high-resolution studio-master- quality digital music.

Its USB input accepts up to 32-bit/384kHz signals and supports DSD64, DSD128, DXD 352.8kHz and DXD 384kHz. Its two coaxial and two optical inputs accept up to 24-bit/192kHz signals, plus its DIN input also connects to select McIntosh SACD/CD transports/ players.

The D150 is a simple and cost-effective solution to adding digital music to an existing system, or with the addition of a power amp, speakers and digital source, the D150 can become the high-performance ‘hub’ of an all-digital set up.

The D150 also boasts a built-in headphone amplifier and uses the same DAC as the D100 (launched at CES 2013) and features an eight-channel 32-bit/192kHz D/A converter (used in stereo Quad Balanced mode.

The D150 is distinctly McIntosh, too: it shares the same classic visuals, controls and hand- crafted black-glass front panels as all the other McIntosh components and yet is easy to position with its compact, 10cm-tall chassis.
