BRYSTON 4B NRB STEREO POWER AMPLIFIER #442464 ORIGINAL BUILD DATE CODE 312 = DECEMBER 1993 PROFESSIONALLY SERVICED OVERHAULED BY BRYSTON IN AUGUST 2018 THIS AMPLIFIER HAS BEEN PACKED IN THE CARTON UNUSED SINCE 2019 TESTED 100% OPERATIONAL CONDITION This listing is for a Bryston 4B NRB stereo power amplifier. I have two of these that were both serviced by Bryston at the same time, please see my other posting. I recently acquired this, it was sent to Bryston in 2018 for service and has sat packed in the carton since 2019. This amplifier has been tested and is in 100% operational condition. Both channels are clean and clear with no hum, buzz, noise, or distortion. It is entirely super quiet at idle, putting your ear to the tweeter you hear nothing. Bryston is one of the old school manufacturers that will renew their components to original specs. The operational condition of this amplifier is a testament to the quality of Bryston service. Sound quality is exceptional, music and film soundtracks are reproduced with clarity and coherence only found with the finest amplifiers. I have been listening to this in my video based system and find no faults. Xfinity cable box as source, Bryston B60 as preamp, speakers ADS L1230. Cosmetic condition is fair, the amplifier looks used, there are some signs of handling, a few scratches and marks, some corrosion on the screw heads on the rear panel, no dirt or nicotine contamination. Sitting in your cabinet or rack it is very presentable. Included will be factory shipping carton with inserts, power cord, and Bryston paper work for service done. If your priority is absolutely the finest sound quality for the money this will not disappoint. I have probably sold more Bryston gear in my career here than even McIntosh. IME this amp is a giant killer in its present state. I will double box this with a new ULINE outer carton for added protection. SOME ADDITIONAL INFO: audio_maven has been dedicated to testing and accurately describing what our buyers will receive. We have sold over 4000 pieces of audio gear online since the year 2001. Although eBay does not display or accredit sellers who have continuous 100% positive feedback with no negatives or neutrals for lifetime this is what we have achieved so far in 22 years. We have worked hard to provide our buyers with quality gear. A WORD ON SHIPPING, INSURANCE, AND PACKING CHARGES: Shipping cost includes FedEx Ground/Home service full insurance and new heavy-duty packing materials. I take packaging very seriously and go to extremes to help ensure that your item arrives safely. Please see my eBay feedback profile for references and rest assured this will be done correctly.

Bryston 4Be (NRB) for sale. The “e” stands for engineering and was the early model of the NRB vintage before the NRB name was introduced. They are the same circuit wise, however there are a very small number of the “e” models produced according to Bryston’s James Tanner. This amp is in fantastic condition. The 3 blemishes it has are so minor they are barely visible. I tried to capture them on camera. It has never been used professionally like many of these were. It’s been my personal amp for a long time and I can say more than it’s “tested and working”. Everything works perfectly. Both channels are working equally and have no hum or noise. I’ve played music for 8-10 hours before and it never skips a beat. It’s never needed service since I’ve owned it and is frequently cleaned inside so it can efficiently dissipate heat. Comes with power cord. Selling because I finally upgraded to the latest 4B. Let me know if you have any questions. Thanks.

Bryston 4B NRB 2 Channel Power Amplifier W/ Rack Handles. Condition is pre-owned. It is in excellent physical condition and looks great. It is tested and working properly. There are only a few minor dings and scratches. I tried to show these in the photos. Heavy duty rubber feet have been attached to the bottom. Comes as shown with rack handles, power cord, and owners manual reprint. It will be carefully packed for shipping, insured, and will require adult signature on delivery. DESCRIPTION/SPECS: The Bryston 4B NRB is a stereo power amplifier that can deliver high-quality sound and performance. It is a class-AB2 solid-state amplifier that uses MOSFET output devices and dual toroidal transformers. It has a slim profile and weighs 42 pound. It also has a bridging switch that allows it to operate in mono mode, delivering twice the power into a single load. The Bryston 4B NRB can produce 250 watts per channel into 8 ohms, 400 watts per channel into 4 ohms, and 800 watts in bridged mode into 8 ohms. It has a very low total harmonic distortion of less than 0.01% at 250 watts, from 20 Hz to 20 kHz. It also has a high signal-to-noise ratio of 100 dB below full output. It has a wide frequency response of 0.5 Hz to 100 kHz, +/-3 dB. It has a damping factor of over 500 at 20 Hz, which means it can control the speaker movement very well. The Bryston 4B NRB is designed to be very reliable and durable. It has a 14-gauge steel chassis that protects the internal components from external interference3. It has a modular construction that allows easy servicing and upgrading. It also has a thermal protection circuit that prevents overheating and damage. The Bryston 4B NRB is a great choice for anyone who wants a powerful and refined amplifier that can reveal the most delicate details in the musical fabric, at the same time providing seemingly endless power reserves. It is suitable for driving various types of speakers, from bookshelf to floorstanding models. It can also be paired with other Bryston components, such as preamplifiers, DACs, and CD players, to create a complete audio system. The Bryston 4B NRB is a classic amplifier that has earned many praises and awards from audiophiles and critics alike.
