    McIntosh MC275 (Two Channel Tube Amp)

    Another new product from McIntosh is the MC275 tube amp.

    This two-channel tube amp is rated at 75 watts per channel into 4, 8 or 16 ohms, with a total harmonic distortion of 0.5% with a frequency response of 20Hz to 20kHz.

    This tube power amplifier has all the features to meet the needs of today’s music enthusiast, while preserving the qualities that have made the MC275 the most revered McIntosh tube amplifier.
    This sixth generation MC275 has many subtle enhancements from the previous release that greatly improve performance. Combined with the widest bandwidth McIntosh output transformer design, the MC275 features tauter bass control and thermally quiet circuit design. The result is pure music.

    McIntosh patented, gold plated, speaker binding posts assure the best connection to all speaker cables, while high quality balanced and unbalanced input connectors enhance signal transfer from the connected preamplifier.

    The seven small tubes are LED illuminated to indicate the amplifiers functional status: upon power up, they sequentially glow amber for a few seconds and then all turn green to signify system readiness (see below). In the rare case of an output tube failure, the small tubes in front of it will turn red to notify you of the problem. Power Control is used to remotely control tube illumination from a McIntosh preamplifier.

    You had better start playing the lottery.

    Saw this at CES and must admit I didn't care much for the green LED lighting. Made the amp look a bit like an aftermarket Scion cruising Sunset Blvd. Their new digital preamp was far more intriguing (to me).

    McIntosh has to work a little bit of green into all their products, it seems. The amp has an interesting warm up sequence. The smaller tubes will light up one at a time, first turning orange, then green. You can see an animation on the McIntosh site.

    I would find the orange, or even the blue they use for their meters, more appealing.
