Up for sale is a pair of Legacy Audio Monobloc Amplifiers. In new condition. Very low hours. A rare piece that is hard to come by. I have the owners manual, but I cannot locate it right now. Buyer must pay PayPal fees. Shipping weight is for one amplifier, you must multiply the shipping by 2 for both amps. The Monobloc is Legacy's flagship power amplifier, producing 800 W continuous into 4 ohms and 450 W continuous into 8 ohms. The design is a collaboration between Legacy's Bill Dudleston and Eric Lauchli of Coda, a well-respected, high-end electronics company. One of the primary design goals was to build an amp that can deal with the range of impedances found in many of today's speakers.
The Monobloc has 20 pairs of matched output devices running on 90 V rails, which, coupled with current capability of over 50 amps, makes it possible to deliver peaks of over 1,800 W (with 4 ohm loads)! All this power originates in a supply that has a 940 VA 60 Hz toroidal power transformer with 100,000 µF of capacitance. Other design highlights include balanced differential operation, direct coupling without servo circuitry, no global negative feedback and a slew rate of 50 V/µs without entering Class B operation.
The Monobloc is 17" wide, 6" high and weighs in at 55 lbs. The attractive black-anodized front panel has a large rocker power switch and a nicely sized lighted meter. The rear panel has only an IEC power receptacle, XLR and RCA connectors for balanced and unbalanced inputs respectively.

$3,000 for the pair, plus PayPal and shipping.

    Sweeet, tell me you tried them out on the 1.2's. Good luck with the sale. I'm thinking audiogon or Legacy's own forum would yield a quicker sale though.

    Tony,
    I never tried them out with the 1.2TL's. I was concerned with common ground issue. I did not want to "break" anything. They have been on Audiogon with no results.
