You are looking at a Bryston 4B3 (4B Cubed) Dual-Mono Power Amplifier.
This amplifier was originally purchased on 28th July 2020, meaning it is only 4 months old. This means this 4B3 has 19 years 8 months remaining on the manufacturers warranty.
The original sales receipt is present and will be included in the box when shipped.
The 4B3 is in beautiful condition (please see photographs): on very close inspection, you may see the odd tiny imperfection, but nothing that we can see.
Ships well packed in a original box with owner's manual and mains cable. There are two mains cables- one for the U.K. and one for Europe. The relevant mains cable will be included; if the amplifier sells to somewhere outwith the U.K. and Europe, no mains cable will be included.

Bryston 4B3 Dual-Mono Power Amplifier (4B Cubed)
A rarified few components in audiophile lore have become so ubiquitous that nearly every music lover once had, lusted after, or if they're really lucky, currently owns one. One such legend is the Bryston 4B. This product has been manufactured continuously (though often refined) since 1978. Currently this venerated amplifier is on its 6th generation, and it's never been better. Now rated at 300 watts per channel into 8 ohms, (and upwards of 500 into 4 ohms), this true dual-mono amplifier is powerful enough for practically any speaker, yet it's priced to remain within reach. The degree of clarity, power, nuance, and outright truthfulness of this amp is stunning.
If you've always wanted one, maybe now is just the right time.
The Bryston 4B³ amplifier is a stereo power amplifier which is acclaimed internationally as being suited for the finest and most sophisticated sound systems. The Bryston 4B3 is currently the most popular Cubed Series model.
At Bryston, finding ways to eliminate distortion from their designs is a way of life. The Bryston 4B3 Amplifier features a new patented input circuit that is precisely optimized and linear beyond any we’ve used before.
The Bryston 4B3 amplifier features twelve active devices in a groundbreaking array, this new circuit both matches the amplifier to virtually any preamplifier and provides the first 6dB of gain. The new input stage is so transparent, its measurable distortion is less than 1/1000th of 1 percent.
Newly designed circuitry in the Bryston 4B3 Amplifier is virtually impervious to noise such as RFI and others induced by external and environmental causes.
The Quad-Complementary topology improves linearity to a new standard of accuracy while virtually eliminating aggressive higher harmonic distortion byproducts. The overall harmonic distribution of Bryston’s Quad-Complementary output mimics the characteristics of a class-A design but with dramatically lower distortion. Each Bryston 4B3 Amplifier channel includes its own fully independent power supply with separate transformer.
Bryston strive for accuracy and transparency because that is what sounds best. When a playback system is faithful to the recording, the listener can enjoy the most subtle details, capturing the depth and soul of the performance as the artist intended.
