McIntosh announced the launch of three new preamplifiers – the C1100, C52 and C47. Handcrafted at their Binghamton, NY factory, each product combines the best-in-class audio performance of the legendary McIntosh Reference System with the latest in technological development.
The C1100 preamplifier brings a new level of performance and luxury to McIntosh’s heralded preamplifier offerings – evidenced by its high level inputs having the lowest noise of any McIntosh preamplifier ever produced. It utilizes a two-chassis design where the control and power sections are completely separate from the audio section. The C1100 is comprised of the C1100 controller and the C1100 vacuum tube preamplifier. Inside each, the left and right channels are electrically and mechanically isolated from each other to allow true dual mono operation - resulting in the ultimate stereo separation and sonic purity. Both units’ chassis are comprised of polished stainless steel and hairline brushed black Titanium stainless steel, offering a new degree of richness and refinement. The C1100 vacuum tube preamplifier houses the audio connections and circuitry, featuring a total of 12 analog inputs: 6 balanced, 4 unbalanced, plus an adjustable loading moving magnet and a moving coil phono input. For outputs, 2 sets of balanced and 2 sets of unbalanced connections provide flexibility in connecting to your amplifier. Twelve vacuum tubes (6 each of 12AX7a and 12AT7) power the tube preamplifier.
The C52 is a single chassis solid state preamplifier with 16 inputs in total, 3 balanced and 4 unbalanced fully assignable inputs plus 3 optical, 2 coaxial and 1 USB input. The C47 has 2 balanced and 3 unbalanced fully assignable inputs along with 2 optical, 1 coaxial and 1 USB. Both also include a moving coil and a moving magnet phono input. The optical and coax inputs on each unit will decode digital music at up to 24-bit/192kHz for high resolution audio playback. For outputs, the C52 has 3 pair of balanced and unbalanced outputs; the C47 has 2 pair of each. Both models are capable of decoding and playing back DSD files for the latest in high fidelity performance; the USB input accepts PCM signals up to 32-bit/384kHz and supports DSD64, DSD128 and DSD256 plus DXD 352.8kHz and DXD 384kHz. In addition, a proprietary MCT input on each offers a secure, custom DSD connection for playback of the high definition audio found on SACDs when paired with the McIntosh MCT450 SACD/CD Transport.
The C52 offers an 8 band analog equalizer that allows you to fine tune your various music sources just the way you like, while the C47 includes bass and treble tone controls.
For personal listening, all 3 models include a headphone jack with our Headphone Cross-feed Director (HXD) circuitry that brings a new depth and feeling of space to your music.
