Sonics 800X (Bryston 7) Hi-Fidelity IMAX Amplifier GREAT CONDITIONINCREDIBLE SOUND FROM BRYSTON COMPONENTSREMOVED FROM LOCAL MUSEUM DURING RENOVATION Sonics 800X (Bryston 7) [ Listing is for 1 amp - however we have 8 units total available ] Overview: Sonics was the American company that supplied the audio systems for the IMAX & OMNIMAX Theaters. Their amplifiers were built by the renowned Bryston in Ontario Canada and Sonics added their front & rear panels along with input circuitry. Over the years these amps have found their way into the consumer/used market and audiophiles jump at the opportunity to own one of these legendary amplifiers. The Sonics 800X is almost identical to a Bryston 7B - they were basically rebadged with Sonics front/back plates with slightly modified circuitry for their use with IMAX systems. Unit come with new 6x30mm 150V fast-blow fuses: The 800X is set up as a monoblock amp, (two mono channels within set up in push-pull configuration) and there are no switches to change from series or parallel. Inside are two identical power amplifiers set for bridge operation for 500 watts into 8 ohms or 800 watts into 4 ohms. Conversion to 2-channel stereo operation is possible by disabling the input module internally. Step-by-step instructions to convert the 800X to a stereo amp can be found below however we assume no responsibility for any issues/damage arising from modifying these amplifiers: https://www.audiocircle.com/index.php?topic=88518.20 UNDERSTAND WHAT YOU ARE PURCHASING:While we cannot guarantee any amp performs 100% as it did when it left Brystons manufacturing facility, each unit has been tested for power handling, clipping, and clean audio on each channel. Some audiophiles choose to send their amps to Bryston for full refurbishment (contact Mike Pickett @ Bryston for details)If you would like us to ship directly to Bryston we are happy to coordinate, provide full tracking info, and save you the additional shipping costs. If a return is authorized, the buyer will assume all return shipping costs. These things are HEAVY.

This Bryston 7b lived in our audio room before we closed the doors for good. Never had an issue and it functions flawlessly. It has lived it’s whole life in a studio equipment room rack, and had regular maintenance done by our house engineers. On a side note here, I do not store it on top of my Marshall amp, that was just the best spot to grab a few pics amidst the mess in our basement (our basement is being remodeled so it’s very out of sorts!!)

Bryston 7B Power AmplifierUpgraded by professionals a couple of years ago, with new/larger capacitors (12,000uF replacing 6,800uF), new Nichicon Muse bipolar capacitor on the feedback loop, added bridge filter to eliminate transformer buzz due to DC content in power supply.Fine tuned bias and output offset. Local pickup preferred. Please contact for shipping or other delivery options.
