McIntosh D1100 2-Channel Digital Preamplifier

The D1100 Digital Preamplifier is a reference level stereo preamplifier and digital-to-analog converter (DAC). Its 8-channel, 32-bit DAC is used in Quad Balanced mode with half of it dedicated to the left audio channel and the other half to the right channel. It’s the most advanced DAC we’ve ever used and delivers an unprecedented level of performance so that all your digital music is reproduced with exceptional accuracy and authenticity.

Enough inputs – 9 to be exact – are included to keep even the largest digital system connected as 3 optical, 3 coaxial (2 RCA and 1 BNC), plus 1 each of MCT, AES/EBU and USB inputs are on board. The USB input accepts up to 32-bit/384kHz signals and supports DSD64, DSD128, DSD256, DXD 352.8kHz and DXD 384kHz playback1. All the other inputs accept up to 24-bit/192kHz. The MCT input is a McIntosh exclusive and allows for enjoying to the high resolution audio found on SACDs via the MCT500 SACD/CD Transport. Three sets of balanced and unbalanced stereo outputs connect the D1100 to your system. One set of outputs has fixed volume while the other 2 have variable volume; the variable outputs can also be switched on and off for additional user configurability.
