"There are few amplifiers that offer a more even, composed, linear character than the 2.5B3. This amplifier is very enjoyable and entertaining to listen to for long periods. No particular trait draws the listener’s attention away from the overall performance due to some imbalance or distracting sonic flaw. The Bryston 2.5B3 Cubed is a fine amplifier that will survive many system upgrades."

"He's an emotionally naked singer, so it's just you and him, and the 2.5B3 makes that perfectly clear. I felt a total connection to his sound, so my audio system melted away, and all that remained was Brosseau and his hollow-body electric guitar. The best components do that; they let the music come through, seemingly without adding or taking anything away."
