Norma Revo-IPA-140 USB DAC

The USB-1 option for the REVO IPA-140 amplifier consists of two independent boards mounted in a sandwich configuration. One contains the digital and filtering stage, while the other contains the analog filtering and output stages. This board should not be considered a mere addition of a digital input, but rather a high-quality solution capable of competing with the best converters on the market. Furthermore, since it is installed inside the amplifier, it eliminates the need for an interconnection cable which, if high-quality, would cost far more than the USB option itself, and perhaps even more than an external DAC. The USB receiver is a Tenor TE8802L, which supports frequencies up to 192 kHz in both synchronous and asynchronous modes. On Apple systems, no driver installation is required.The digital-to-analog converter used is the Wolfson WM8741, one of the most modern and highly regarded DACs, which can operate at up to 24 bits and 192 kHz (with internal 32-bit calculations). The digital board features three independent voltage regulators, plus a local, highly stable, low-phase-noise oscillator.Three different digital filters can be selected simply by connecting the jumper on the board, allowing for different temporal and phase responses. Particular care has been taken with the analog section: thanks to a proprietary solution, only one active stage is in the signal path, minimizing its impact on sonic performance. The board can be easily installed in the device at any time. Revo IPA-140 The Norma Revo IPA-140 integrated amplifier is a definitive choice for amplification. Its high power (140W/8Ohm) and ability to drive even the most demanding speakers make it an extremely versatile amplifier. This versatility is enhanced by the ability to customize the input/output connections and install the Phono MM/MC board. The elegant and sophisticated design perfectly complements its sonic character. Power, dynamics, speed, and transparency combine to create outstanding musicality and a complete absence of listening fatigue. Its internal design reveals that the technical refinement follows the same philosophy. The Revo IPA-140 uses proprietary circuitry, regulated high-speed power, and low-noise components, and is built using a carefully selected range of the finest available materials.
