D150 Preamplifiers

The D150 digital stereo preamplifier expands McIntosh's digital music capabilities by supporting many of the newest digital audio formats such as DSD and DXD. A USB input accepts up to 32-bit/384kHz signals and supports DSD64, DSD128, DXD 352.8kHz and DXD 384kHz. Two coaxial and two optical inputs accept up to 24-bit/192kHz signals. It is a simple solution to add the latest digital music formats to your existing system.

The D150 and MCT450 "just ran happily and unobtrusively, doing what they were asked, and doing it to the highest possible audible standards... They bring together the very highest levels of high fidelity performance, and reliable, feature-laden delivery. This is truly impressive gear." - Audio Esoterica

The D150 and MCT450 combo plays “perfectly and in the right way... the dynamics of these two McIntosh seems to have no comparison!” - audio-activity.com

For price, performance and overall rating, the D150 and MCT450 were awarded the Uber level with 97 points out of 100. - Stereoplay


Balanced and unbalanced connections are available for both variable and fixed volume audio outputs, providing flexibility in setting up and connecting your system. Or simply add an amplifier, a pair of speakers and a digital source for a complete digital based stereo system. For enjoying SACDs, the unique DIN input connects to select McIntosh models with a DIN output - like the MCT450 SACD/CD transport​​ - to deliver the purist possible sound quality. It's also flexible enough to be used as a headphone amplifier; just connect your digital sources and a pair of headphones, such as the MHP1000​ (not included), for a personal listening experience.

After using the D150 and MCT450, McIntosh "digital products are as excellent as their amplifiers, the quality is stable and fabulous as usual and also able to integrate with the Hi-Res audio trend. McIntosh products are equipped with various functions, making them flexible." - Audio Technique

The D150 uses the same revered DAC as the D100, featuring an 8 channel, 32-bit, 500kHz D/A converter with wide dynamic range and extremely low distortion. Eight channel D/A converter is used in stereo Quad Balanced mode. Music at all levels is reproduced with extreme precision and elegance. A 1/8” mini jack is provided for control data from the data output jack of a McIntosh preamp or A/V Control Center​. It shares the classic façade, knobs and handcrafted black-glass front panels as all other McIntosh components in a small form factor of just under 4" in height.​
