Bryston 4B-ST Solid State Stereo Amplifier in Box, Under Warranty

$1,999

We were about to write about Bryston's unique background related to this hand-built and elegantly designed amplifier - but their website really says it best:

"Bryston Ltd. has been designing and manufacturing state of the art specialty electronics to both the consumer and professional audio marketplaces for over 35 years. Bryston engineers are never constrained by design costs for functionality. On the contrary, Bryston challenges their engineers to create the finest products they can; to source and use the best components; to move Bryston equipment ever-closer to perfection, while maximizing performance and reliability.

Following in the fine tradition of artisan craftsmanship worldwide, every audio component is handcrafted by people who take tremendous pride in building the very best. Each component is hand selected and installed, every wire is cut and bent by hand, and every connection is hand soldered.

Each of Bryston's fully assembled products is extensively tested before shipment. During 100 hours of continuous testing, Bryston amplifiers are monitored through a range of input cycles and thermal stress levels to duplicate a broad spectrum of operational loads. If any failures occur, Bryston will catch them during the manufacturing process, before you begin using the product.

Bryston's dedication to creating the most reliable products is clearly evident in their 20 year analog and 5 year digital warranty."

Some standout 4B-ST features from the Owner's Manual:

"The Bryston 4B-ST stereo amplifier consists of two amplifier modules, each with its own +/- 85v power supply.  Each of the two amplifier modules uses eight of Bryston's custom power transformers for a total of 16 output devices.

The two channels may be operated independently, (at 250 Watts per channel @ 8 Ohms, 400 Watts @ 4 Ohms), or combined to form a single 800 watt monaural amplifier into 8 Ohms." And distortion is less than 0.007% from 20Hz to 20kHz!

The 4B-ST has a power switch front and center, then out back there's a stereo/mono switch, gold-plated input/output connectors, balanced XLR and unbalanced RCA inputs, and a 12V trigger that offers an adjustable turn-on delay of 0 through 4 seconds.  And the ground-lift switch?  It actually "lifts" the internal circuitry while still grounding the chassis to aid in resolving potential ground-loop hum issues.

This amp was fully tested on our workbench to meet or exceed manufacturer specifications using appropriate pro-level testing equipment, and powered for a solid run in our listening room with smiles all around.

Dimensions: 5-1/4" H, 19" W, 15-1/2" D.
