Full digital resolution

The output levels are kept at 24-bit resolution when operated at most typical listening levels. Within this range, regulation is carried out purely by the DC/DC-converter by adjusting the supply voltage to the amplifier output stage. Essentially, the Model A1 can be regarded as a high-powered Digital-to-Analog converter.

Thanks to its high-end DC/DC conversion, the Steinway & Sons amplifiers features volume adjustment while maintaining full digital resolution at typical listening levels. This unique and technically demanding solution ensures unsurpassed control, noiseless at all sound levels.
