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 NRP Pro original UK version with gain controls This is the NRP version This is 1 ohm stable !!! you can switch the two internal modules to be series or parallel for 8 down to 1 ohm , Switch on rear of amp Specs are 500w 8 ohm load, 800w 4 ohm load, (I think 900w 1 ohm the manual is a little vague as they state minimum conservative values)

Sonics 800X (Bryston 7) Hi-Fidelity IMAX Amplifier TESTED BUT CHANNEL A IS WEAKER AND THERE ARE ALMOST NO LOW FREQUENCIESSOLD AS-IS FOR PARTS/REPAIRNO RETURNS Sonics 800X (Bryston 7) 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. 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 !
