Description
Bryston BD-325 Class D Amplifier
The Bryston BD-325 Class D Amplifier is a very interesting move from Bryston because it brings the brand’s reputation for power, reliability, and studio-grade control into a more efficient Class D platform.
What stands out is that this is not a typical compact switching amplifier. Bryston has approached Class D in its own way, using a serious chassis, high power reserves, and a linear power supply philosophy rather than simply chasing small size and low heat. That gives the BD-325 the kind of authority customers expect from Bryston, but with the efficiency and installation flexibility that Class D can offer.
The modular configuration is a major advantage. Being able to specify 1, 2, 3, 4, 5, or 6 channels makes the BD-325 extremely useful across different systems. It can work as a powerful stereo amplifier, a three-channel front-stage amplifier for home theatre, or a full multi-channel amplifier for surround, height, or active speaker applications.
In NZ homes, this makes a lot of sense for larger theatres, premium stereo rooms, and custom installations where space, heat, power, and channel count all matter. The 325W per channel output gives it excellent headroom for demanding speakers, while the 650W into 4 ohms rating suggests strong current capability for more difficult loads.
For customers who want the power and long-term confidence of Bryston, but prefer the efficiency and flexibility of Class D, the BD-325 is a very compelling amplifier.

Frequently Asked Questions
- Is the Bryston BD-325 really a Class D amplifier?
Yes, the BD-325 is part of Bryston’s Class D amplifier range. It uses PWM switching amplification, which allows high power output with greater efficiency than traditional Class AB designs. Unlike many lightweight Class D amplifiers, Bryston combines this topology with a substantial chassis and linear toroidal power supply approach. - How much power does the Bryston BD-325 produce?
The BD-325 is rated at 325 watts per channel into 8 ohms and 650 watts per channel into 4 ohms. This makes it suitable for demanding loudspeakers, larger rooms, high dynamic range music, and serious home theatre applications. - How many channels does the Bryston BD-325 have?
The BD-325 platform can be configured with 1 to 6 independent Class D amplifier modules. This means it can be ordered as a mono, stereo, three-channel, four-channel, five-channel, or six-channel amplifier depending on the system requirement. - What systems is the BD-325 best suited for?
The BD-325 is ideal for high-performance stereo systems, premium home theatres, active speaker systems, and custom installations. It is especially useful when you need high power, multiple channels, and efficient operation in one chassis. - Does the BD-325 have balanced inputs?
Yes, available dealer specifications list both RCA and XLR input options. Balanced XLR connection is useful in higher-end systems and longer cable runs because it can help reduce noise. - Is the Bryston BD-325 made in Canada?
Yes, Bryston states that its amplifiers are engineered and manufactured in Ontario, Canada. Bryston also tests each amplifier for 100 hours before it leaves the factory. - What is the difference between the BD-325 and a traditional Bryston Class AB amplifier?
Traditional Bryston amplifiers use Class AB topology, while the BD-325 uses Class D switching amplification. The BD-325 offers high efficiency and modular channel flexibility, while still aiming to deliver the power, control, and reliability Bryston is known for.
