From Bert Whyte - Audio Magazine in 1992

After extended listening with the FM 266, I was impressed in much the same way as I was by its companion FM 811 power amplifier, which is to say that its absolutely effortless dynamic music expression could take me from hushed string pianissimo to awesome fortissimo orchestral tuttis instantaneously. There was no lag or delay, no sense whatever of any kind of com pression or limiting due to circuit inadequacies.
The full gamut of orchestral dynamics was present with a verisimilitude equaled only by the live concert experience. You expect a truly clean signal from equipment of this caliber, but I was amazed at the low-level sounds or, when there were rests in the music, at the utter silence.

The FM 266 was utterly and absolutely sonically transparent, with not even a vestigial hint of hum or a single noise artifact.
I've used balanced equipment for many years in my recording activities, and the stunning performance of the FM Acoustics 266 preamplifier made the case for a balanced system more convincing than ever.
