It’s hip to be square. Huey Lewis knew it 20 years ago. Bryston is cool with it now.
The Canadian manufacturer has introduced its latest high-performance amplifiers, the SST “Squared” Series of amps that incorporates upgrades on eight models of Bryston’s SST family.
The SST amp lineup runs from the 2B SST (100W per channel/8 ohms, $2,650) to the 28B SST (1000W mono/8 ohms, $8,000), and depending on the model, upgrades include:
- Power supply circuit board—No point-to-point wiring in the new SST Squared design, with all components plugging directly into the power supply circuit board;
- Output chokes—New output chokes that extend the high-frequency bandwidth at 20 kHz;
- Soft-start circuitry—Power gets ramped up gradually so there’s not as much strain on the AC supply using a micro-controller;
- Push-style power switch—Replaces the membrane switch on previous models, for better functionality and durability;
- Simplified circuit topology—A reduced circuit board count and less point-to-point wiring for greater efficiency and sonic clarity;
- Power supply transformer design—So you get instantaneous current and less noise (unless you’re into heavy metal—then you’ll still get plenty of noise).
Overall, Bryston’s giving you improvements without changing the pricing, a kind gesture we’ll take from our friends from the North.
