Pro Reviews

"It was time to give the Bryston Middle Ts a turn with the 14B³. These proved to be amazing speakers that sound so much larger than one would expect, given their slender footprint. I played all the previous tracks again, as well as others, and I heard just how well the 14B³ controlled the Middle T, displaying deep articulate bass with just the right amount of mid-bass." - Greg Handy,
"The Bryston amplifier is a bit of a dynamic weapon, along similar lines as other very expensive amplifiers that have graced the listening room." - Edgar Kramer, Audio Esoterica
"If you are looking for amplifier honesty and the ability to drive any speaker in the largest of rooms, or just like the power reserve on hand in your modest listening area, this is one to consider." - John Gatski, Everything Audio Network Read Full Review
