Original owner, excellent condition from a smoke-free home, 2.5 years old. Selling due to a change from Magnepan speakers to high efficiency speakers and low power tube amps.
Rated at 500 watts per channel into 8 ohms, and 900 watts per channel into 4 ohms. Absolute Sound magazine Editor's Choice recommended amplifier in 2016 and prior years. To quote Robert E. Greene's review, "The Magtech sounds as if it has infinite power into anything with total stability”.
One of the best amplifiers made, and at a reasonable price.
Many reviews on the Sanders website here:
Shipping is a flat $100 (or actual cost if lower) to continental US only. Buyer pays 3% PayPal fee.
The box and all packing are in excellent shape, 24" x 21" x 13" and 60 pounds packed. Local pickup gladly offered or I can meet in the Seattle / Tacoma area for a cash sale.
The Magtech amplifier is the only amplifier on today's market that features a linear voltage regulator. The result is a compact, yet extremely powerful amplifier that is ideally suited to driving loudspeakers requiring high power, including those most difficult to drive.
The regulator in the Magtech amplifier maintains a stable voltage regardless of load or reasonable changes in the line voltage feeding the amplifier. It runs stone cold, produces zero RF energy, and is simple and reliable.
Unlike other amplifiers, the distortion in the Magtech amplifier is virtually unchanged regardless of power level. The bias is stable regardless of load.
The Magtech is compact enough (17" wide, 5-1/2" tall, 14" deep) to place on a shelf or into a cabinet. It is also light enough (54 pounds) to be picked up. It runs very cool and may be left on continually without concern for power usage.

Lifetime warranty to original owner, not transferable. Per Roger Sanders: “The equipment is built to the highest possible quality standards, so that we can offer a lifetime warranty. Therefore it is unlikely that future owners would have any trouble with it. But nothing is perfect. If a problem occurs, we will repair it at a reasonable and modest charge."
