Blue Dragon Power Cable

Sold Individually

7B³ mono amplifiers are truly special. Though they don't look much different, they're a big step up from the venerable 4B³. The power supply for this amplifier is built around a specially wound transformer that is substantially more efficient than normal. With twice the power available, they can drive all but the most brutal loads to lifelike levels. But even at whisper quiet levels, they reveal detail and nuance in your recordings that you never knew existed until now.

Bryston provides excellent transparency, ease of listening, and musicality in it's latest single channel (mono) 7B³ amplifier. The Bryston 7B³ offers excellent freedom from overload on any type of speaker. Bryston is known for high-quality audio gear and the 7B³ is no exception.

The Bryston 7B cubed provides excellent transparency, ease of listening, and musicality in it's latest single channel (mono) 7B³ amplifier. The Bryston 7B³ offers excellent freedom from overload on any type of speaker.

"The 7B³ is more refined sounding and more musically rewarding than previous Bryston amps I have heard."

— Kirk Midtskog, The Absolute Sound

The 7B³ mono amplifiers deliver 600 watts into 8 ohms. You can see the attention to detail in the binding posts’ spade slots design. They face upwards making cable connection easy and allows you to route speaker cables away from the floor. The 7B3 has a refined sound and feels more musically rewarding than previous models.

"Overall, the 7B-3s are probably as delightful-sounding as any amps I've auditioned. They are completely without a familiar sonic signature, yet immensely melodious and transparent, and absolutely effortless in reproducing the kind of dynamic range one may get at live performances of large orchestral music."
