Bryston is one of a few companies you can count on one hand that has a 20 year parts and labor warranty, which is transferable (if your kids inherit the component, or you sell it, trade it, whatever). That in itself is a rarity that makes the company worth taking notice of and listening to their products. It means they are built like the proverbial Sherman Tank. When I lifted the 3B and 5B, I realized this, and quickly assigned the task of moving them into place to one of our younger and more-in-shape staff. Wow, is she strong 🙂

The 3B is a two channel power amplifier, while the 5B has three channels. Both are rated at 120 watts/ch rms into 8 Ohms and are THX-Certified. Both models clip at around 150 watts/ch (8 Ohms).
