” Tonal balance is a curious audio parameter. Careful listeners often hear what sounds like an uneven or tilted frequency balance, even when measurements taken under lab conditions show it to be flat. Lots of real-world factors might account for this, including interaction of an amplifier’s output stage with the complex input impedance of a loudspeaker. At first, I thought the AHB2 sounded less bright, and less full in the bass, than the other amps I had on hand, but after only a few days of listening I began to accept that it sounded more “right” than any of them. Now the treble wasn’t so much un-bright as smoother and unaccented. The bass had all requisite extension and detail (see above), but seemed to be more naturally balanced with the rest of the audio band.”
