Bryston - 3B-SST2 17" - 150 Watt Stereo Amplifier
With our unique SE upgrade technology, which rids RFI/EMI contamination, for a much clearer, more effortless, more powerful and more dynamic performance. Our upgrades equal or surpass the most expensive makes and models manufactured today!
Bryston - 3B-SST2 - 150 Watt Stereo Amplifier and our Signature Edition upgraded already included for one low price!
Bryston's 3B-SST2 stereo amplifier, at 150 watts-per-channel into 8 ohms and 250-watts-per-channel at 4 ohms, provides all the quality and value of the company's larger amplifiers but in a package which is both compact and powerful. It is beautifully suited to a wide range of audio/video systems where sonic accuracy, medium power, and long-term reliability is required.
"This compact £1725 amplifier is, for me, a greater achievement than the 14B-SST delivering performance that matches its bigger brother in a more compact package at under half the price," raves England's Hi-fi Newsmagazine. "I have no doubt that unless you have a very large room or exceptionally inefficient speakers then you would be as well purchasing the 3B instead of the 14B and spending the rest on more music - this amplifier is that exceptional."
"If an amplifier is supposed to disappear and become an acoustically invisible conduit for the music, the new 3B-SST does it better than any other amplifier I've heard, or as the case must be, not heard," reportsAudio Ideas Guide. "This one's a keeper, too."
"Vanishingly Low Distortion"
"There are lots of 150 watt per channel power amplifiers out there, but Bryston's claim to fame is its vanishingly low distortion," John E. Johnson, Jr. in his September 13, 2010 review for Secrets of Home Theater and High Fidelity. "If you are searching for an amplifier that delivers what the source sends to it and pretty much nothing else, your search is over."
The 3B-SST2's features list includes a soft start circuit on power up and multiple filter capacitance per channel for smooth and quiet operation. It also offers selectable inputs for balanced or single ended (RCA) connectors, remote 1-volt power trigger input with delayed output feature, and selectable gain settings.
Bryston SST2 C-Series Upgrades
Bryston's SST2 C-series amplifiers are the direct results of the company’s ongoing quest to improve its already legendary SST C-Series product line.
For over 30 years, Bryston has committed itself to designing and manufacturing the most accurate and reliable audio electronics. The performance, value, and reliability of Bryston amplifiers, and the unrivaled warranty, have earned the company critical acclaim and awards worldwide.
Bryston maintains an extensive research and development program, constantly investigating techniques, technologies, and devices that promise improvements to all aspects of its amplifiers. The Bryston SST2 C–Series is the direct result of this ongoing quest, and represents a significant step forward in the art and science of audio amplification.
The SST2 C-series answers the need for today's increased dynamic range and clarity in recordings and movie soundtracks. The end result surpasses the parameters of the most demanding material available.
Upgrades over the previous series include new power supply transformer design plus a new power supply board, push on/off power switches, enhanced chassis design, new 'Soft-Start' circuitry, and new balanced input stage. This series also offers a bridging mode performance improvement, reduced point-to-point wiring, reduced circuit board count, and a redesigned output choke.
Design Philosophy Ensures Sonic Superiority
From input to output, all the circuitry has been optimized for the most accurate performance possible. All analog signal circuitry is fully discrete to avoid the compromises, phase shift, and non-linearities inherent in IC's. The amplifiers incorporate an innovative gain stage topology, which yields a substantially lower noise floor through the use of low-impedance pathways within the amplifier, and has strong advantages in reducing overall distortion.
Bryston's computer controlled distortion analyzers confirm that IM distortion of less than 10 parts per million (below 0.0009%) are typical for this new circuitry. All SST amplifiers use Bryston's proprietary output stage, which we call "Quad-Complementary." The Quad-Complementary topology improves linearity to a new standard of accuracy, while virtually eliminating aggressive higher harmonic distortion products.
The overall harmonic distribution of Bryston's Quad-Complementary output stage closely approaches an ideal Class-A output, except that the overall distortion is actually much lower. (True class-A output stages suffer from relatively high current-induced distortion levels, consisting of mostly lower-order harmonics).
The listening characteristics display a high degree of transparency without harshness or grain. The annoyances previously ascribed to 'transistor sound' are absent, and the amplifier seems to combine the seductive lushness of tube equipment with the focus and accuracy of solid-state.
Modular Design/Independent Power Supplies
No matter how good an amplifier's signal path may be, it's meaningless if it's starved in the power supply, an all too common way of cutting costs. One of the things that makes the Bryston SST Series unusual is the company's insistence that every amplifier in the line have a completely separate and independent power supply for each channel, including its own toroidal transformer.
Bryston's research has shown that separate power supplies provide the best imaging, clarity, and dynamic range , all attributes that are especially crucial given the emerging and demanding high resolution digital sources. The power supplies employ multiple filter capacitors per channel, rather than single pairs of larger filter cans, allowing improved high frequency response, and reducing overall losses in the supply. In the 9B SST, and 6B SST models, Bryston carries the modular concept further, making the channels removable.
Bryston uses only the finest components, such as 0.1% metal-film resistors, polypropylene capacitors, custom-wound toroidal transformers, and hand-matched transistors, to reduce noise and distortion to the absolute minimum. Gold-plated balanced or single-ended (RCA) input connectors are standard as well as gold-plated 5-way loudspeaker binding posts, to eliminate possible causes of distortion from corrosion. As befits products intended for use on stage as well as in the home, the SST chassis are extremely robust.
SST amplifiers offer feature flexibility. For example, all allow a choice of input connection — balanced XLR-F, balanced 1/4" phone, or single-ended RCA jack — together with a switch to select gain settings. A trigger input allows system-wide on/off control. Overall, the SST Series itself facilitates flexibility in putting together the total system through a variety of channel and power output.
Unique Burn-In Procedure
For Each and every Bryston audio product undergoes an extensive quality control "burn-in" procedure. Following a complete operational checkout, every amplifier is placed on a test-bench and run for 100 hours at full output (one-hour on/one-hour off for additional thermal stress), with a high frequency square-wave input and a capacitive load. This extremely rigorous burn-in quickly "matures" components and weeds out any potential premature failures. The result is reliable trouble-free performance for many years.
Easy System Upgrades
Bryston designed the SST Series to take into account that systems change. There’s a full range of channel and power options, several amplifiers may be operated in bridged mono mode, and the 9B SST may be ordered with as few as three channels, and later expanded up to five channels.
