The McIntosh D150 Preamplifier –
a McIntosh Masterpiece… a stereo preamp with a digital mind and an analog soul !!
A preamp/DAC that you can use as a preamp... or a DAC. Even audio components that focus on digital audio owe a big part of their sound quality to analog circuitry. And nobody has more experience with high-performance analog design than McIntosh. The D150 is a component which brings that world-renowned McIntosh sound quality to the latest in high-resolution digital audio formats. Hear what you've been missing from your high-res digital files !!
If your music system is built around digital sources, the D150 is probably all the preamp you need. Just connect the D150's variable-level outputs to your amplifier and you're good to go. You'll use the D150's remote to control volume and other functions, just as you'd expect. But if you also listen to analog sources, and already have a preamp or A/V pre/pro that you like, you can still take advantage of the D150's superb DAC section. Just connect all your digital music sources to the D150, then use its fixed-level outputs to connect to your preamp. In that situation, volume level is controlled via your existing preamp.
With 6 audio inputs, the D150 is a versatile digital preamp with an advanced digital-to-analog converter (DAC). This is an 8-channel DAC chip configured to operate with four channels per stereo channel, and all that processing power will provide a revelatory improvement to the sound from your computer, disc player, music streamer, or TV.
The D150's optical and coaxial digital inputs support high-resolution music files up to 24-bit/192kHz. And its USB input handles even higher-resolution files: up to 32-bit/384kHz for PCM, as well as DSD and DXD formats. The D150 is also one of only a handful of components in the marketplace with a digital DSD input.
