Accuphase Pure Class A power amplifier A-46 for sale. Amp is US voltage. I am the second owner. I will not even try to use the audiophile reviewer type language but will say it sounds “luscious”! Unfortunately, it is too big for my cabinet. Everything works and looks great. I am rating an 8 for age. But the condition of the item is a 9. Only selling to be able to have amp that fits into cabinet… Happy wife, happy life.
Asking price is $5250 shipped and insured. Low ball offers will be ignored. Accepting paypal only, buyer to pay paypal fees. Will only ship to CONUS lower 48. Local pick available. I will meet anywhere within 100 miles of Savannah, GA.
Might consider trade for nice pair of stand mount speakers and cash on remainder of balance either way. Let me know what you have.
Comes with original box. The box is a little rough but I will enclose in outer box so the original will not get scuffed up anymore.
Original retail price was $17,500

Pure Class A power amplifiers from Accuphase have long been blending the purity of class A operation with the superior performance of power MOS-FETs. Acclaimed by audiophiles the world over, these products reflect a level of technical know-how that is second to none. Each model in the A-65/A-45/A-35 lineup has received high praise, both for sound quality and performance. The A-46 is a minor-change successor to the A-45, positioned as the medium power level model of the series. Naturally, the A-46 also demonstrates the same unwavering dedication to sound quality and outstanding design policy which are the hallmark of Accuphase. This pure class A stereo power amplifier with its distinctive external heat sinks is built for the true enjoyment of music. The A-46 uses latest instrumentation amplifier topology throughout, which allows fully balanced transmission in all signal handling stages. The power amplifier section features further improved MCS+ topology and the renowned current feedback approach. This results in electrical characteristics that surpass even the demanding standards set by its predecessors. Employing only highest grade materials and strictly selected parts, the A-46 realizes very low output impedance which ensures that constant drive voltage is available for the speakers. The output stage features power MOS-FETs renowned for their excellent sound and superior reliability. For each channel, six of these devices are arranged in a parallel push-pull class A arrangement. MOS-FETs have excellent frequency response characteristics and high input impedance, which reduces the load of the preceding (drive) stage. Driving these devices in pure class A means that constant power is always supplied, regardless of the presence or absence of a musical signal. This makes the amplifier completely immune to external influences and ensures stable operation at all times. The large heat sinks mounted on the outside reliably prevent internal heat buildup, allowing the amplifier to sustain output levels of as much as 360 watts per channel into 1 ohm (with music signals). If even higher power is required, bridged mode turns the A-46 into a high-grade monophonic power amplifier.
