11.Only use attachments/accessories specified by the manufacturer.

12.Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13.Unplug this apparatus during lightning storms or when unused for long periods of time.

14.Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

"WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR MOISTURE".

"DO NOT EXPOSE THIS EQUIPMENT TO DRIPPING OR SPLASHING AND ENSURE THAT NO OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, ARE PLACED ON THE EQUIPMENT".

"TO COMPLETELY DISCONNECT THIS EQUIPMENT FROM THE AC MAINS, DISCONNECT THE POWER SUPPLY CORD PLUG FROM THE AC RECEPTACLE".

"THE MAINS PLUG OF THE POWER SUPPLY CORD SHALL REMAIN READILY OPERABLE".

BP20, BP25 specifications

The Bryston BP25 and BP20 represent a pinnacle of engineering in the world of high-performance audio preamplifiers. Renowned for their exceptional sound quality and meticulous design, both models are integral components for audiophiles seeking unparalleled audio fidelity.

The Bryston BP25, with its robust construction and audiophile-grade components, delivers a highly transparent audio signal that preserves the integrity of the original recording. One of the standout features of the BP25 is its fully balanced differential design, which helps to minimize noise and distortion. This topology results in a cleaner, more detailed sound, making it an ideal choice for critical listening environments.

Equipped with a comprehensive range of inputs and outputs, the BP25 accommodates various audio sources, including CD players, turntables, and digital audio players. One of its notable features is the inclusion of both XLR and RCA connectors, allowing for versatile connectivity options. The BP25 also features a high-quality headphone output, making it a versatile solution for both casual listeners and serious audiophiles who demand superior performance across different listening scenarios.

On the other hand, the Bryston BP20 is a more streamlined model that inherits many of the technological advancements seen in the BP25, but in a more compact form. The BP20 retains the essential elements of Bryston’s design philosophy, offering low noise and high dynamic range. While it has fewer inputs and outputs compared to its larger sibling, the BP20 is still capable of delivering a robust listening experience that rivals many higher-end competitors.

Both preamps leverage Bryston’s legendary build quality. Constructed in Canada, every BP25 and BP20 is meticulously assembled, with an emphasis on long-term reliability and durability. The use of premium grade components, including high-quality capacitors and resistors, ensures that these preamps provide consistent performance over time.

In terms of technology, the BP25 and BP20 utilize Bryston’s proprietary DC power supply, which significantly enhances the overall audio performance. This innovative power supply minimizes unwanted noise and ripple, resulting in a pure power source for the preamps.

With their exceptional performance, diverse connectivity options, and durable construction, the Bryston BP25 and BP20 preamps represent a commitment to quality audio reproduction, making them standouts in any high-fidelity audio system. Whether you are building a new system or upgrading an existing one, both models are worthy choices that promise to elevate your listening experience to new heights.
