McIntosh C1100 Tube Preamplifier and Controller
McIntosh’s newly announced C1100 tube preamplifier and controller pushes the limits of what’s possible. The C1100’s dual-chassis design produces less noise than any other McIntosh preamp ever made.
The two unique sections provide the purest sound reproduction possible by completely isolating a preamplifier’s two main functions:
- Control
- Sound
The C1100 is made up of two sections:
- C1100 Controller
- C1100 Vacuum Tube Preamplifier
Inside each, McIntosh electrically and mechanically isolates the left and right channels to allow true dual mono operation – giving you the ultimate stereo separation and sonic purity. A pair of high performance, shielded umbilical cables prevent outside noise from leaking into the audio signal between the Tube Preamplifier and Controller.
Even in two separate units, they act in unison and are easily controlled with both the remote control or the C1100 Controller front panel.
C1100 Featuress
The C1100 houses many connections between the two pieces, so here’s a breakdown of what you get with the Controller and Tube Preamplifier.
For the Controller’s connections:
- Power control
- Data ports
- External control

The Controller also introduces a dual microprocessor for an improved, robust control system.
The Tube Preamplifier houses the audio connections, including 12 analog audio connections like and 2 sets of outputs:
- 6 balanced inputs
- 4 unbalanced inputs
- Adjustable loading Moving Magnet phono input
- Adjustable loading Moving Coil phono input
- 2 sets of balanced outputs
- 2 sets of unbalanced outputs

The Tube Preamplifier features 12 vacuum tubes (6 – 12AX7a and 6 – 12AT7). The C1100 has 4 more tubes compared to the C1000 which had 8 tubes. The C1100’s additional 4 tubes lowers dependency on any solid-state support.
The amplifier circuit features a higher common mode rejection to reduce noise introduced by interconnect cables.
For headphone listening, McIntosh uses a headphone jack with higher output compared to any other Mac preamp. The Headphone Crossfeed Director (HXD) adds depth and spatiality to your music.
Use the Home Theater Pass Through feature to seamlessly integrate this into your existing surround sound home theater system.
The C1100 preamp features McIntosh’s classic black glass front panels, blue meters, knobs, stainless steel chassis, illuminated logos, and custom machined brushed aluminum end caps. The C1100 can be matched with McIntosh’s amplifiers, speakers, room correction devices, CD players, turntables, tuners, and other sources for a complete home audio system.
