This is best preamp McIntosh ever made. All analog with no pesky DAC's that will be outdated in a year.

First launched in September of 2015 with the lowest noise of any McIntosh preamplifier ever produced.

The phono section is also superb with no need to go external.

Featuring a Dual-Chassis and Dual-Mono design.

Like new and well cared for.

Comes to you complete with the original McIntosh remote, manual, and double shipping cartons.

McIntosh C1100 All Tube Flagship Dual-Chassis Preamplifier - Owners Manual

Standout Features Include:
• Dual Chassis with Dual Mono Design
The Dual Chassis design completely separates all power supply, microprocessor and control circuits from the pure audio circuits for total noise isolation. To further aid in channel isolation, the circuitry for both channels is totally separate, physically isolated and shielded. The C1100C incorporates two identical power supplies one for each channel, to help assure total channel isolation.

• Fully Balanced Circuitry
The C1100T utilizes the very latest in Fully Balanced Circuitry from the Input Connectors all the way to the Output Connectors for the lowest possible noise and distortion.

• Electromagnetic Input Switching with Level Trim Adjustment
Digital Logic integrated circuits drive Electromagnetic Switches on all Inputs and operating functions for reliable, noiseless, distortion free switching. All the Inputs on the C1100T can be matched in level, so there are no abrupt changes in volume levels between the different Inputs.

• Moving Coil and Moving Magnet Phono Inputs
The C1100T has two precision Phono Preamplifier Circuits, one for Moving Coil Phono Cartridges and
the other for Moving Magnet Cartridges. Both phono inputs have selectable loading. The circuits use the latest designs providing the lowest possible noise and distortion. The close tolerance resistors and capacitors used in the RIAA Correction Equalization Circuitry provide an extremely flat frequency response.

• Precision Tracking Volume Control
Volume levels are controlled by a Precision Balanced Digitally Controlled Attenuator System with an Optical Encoder Rotary Control. This assures a 0.1dB tracking accuracy between channels. There are 214 individual 0.5dB volume level steps with no noise as the volume level is changed.

• HXD® for Headphones
The C1100T Headphone Crossfeed Director Circuitry (HXD® ) improves the sound localization for Head- phone Listening. HXDTM restores the directionality component of the spatial sound stage normally heard with Loudspeaker listening.

• Dual Special Power Supply
Two fully separate and regulated Power Supplies with special R-Core Power Transformers ensure stable noise free operation even though the power line varies.

The SkyFi Testing Process for Preamplifiers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline.

At this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching.

Final testing involves putting actual music through the preamplifier. We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage KEF speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.
