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.
