McIntosh – C1000/C1000P / (pre-owned)

Product Description

McIntosh – C1000/C1000P  

Product of the Year!

The debate over whether tubes or transistors sound better is still going strong after forty years.

McIntosh has led in both technologies, and has just raised the bar again, with the C1000,

Stereophile Magazine’s 2006 Amplification Product of the Year. The C1000 is a three-chassis design that offers the ultimate in flexibility.

It lets the listener choose between a solid-state preamplifier, vacuum tube preamplifier, or both.

All three modules can be combined with each source available through either preamplifier module, selectable at the push of a remote control button.

For ultimate stereo fidelity the preamplifier modules employ Dual Mono topologies yielding over 130 dB of channel separation.


All three balanced outputs carry the same signal and bypass switching when the TRI-MODE is programmed.

This allows tri-amplification of a speaker set, while the unbalanced outputs will still switch to control a remote amplifier.


The output attenuator controls volume over 214 steps of .5dB each with accuracy within .1dB.

The volume versus rotation rate varies as preamplifier gain varies and attenuation changes occur at

the zero crossings of the audio signal to prevent audible artifacts during adjustment.


Signal routing is accomplished through digitally controlled electromagnetic switching devices.

Precision switch contacts, isolated from environmental contamination inside inert gas-filled tubes,

provide the most reliable, quietest and lowest distortion switching possible.


Moving Magnet has adjustable capacitance from the remote to allow flexibility in matching your favorite turntable.

Moving Coil offers adjustable resistance also from the remote control for the same flexibility.
