How can you improve on the best DACs and analog stages in the world? By eliminating them, says Classé and that’s, probably, the secret to the powerful performance/price ratio delivered by their new Sigma 2200i stereo integrated amplifier. By connecting the output of the 2200i’s preamp section DSP directly to the input of the amplifier DSP, Classé eliminates DAC and ADC conversion losses and their associated analog circuitry’s noise and distortion. By keeping digital signals digital all the way to the amplifier output filter, Classé shortens the signal path, avoids losses and eliminates Digital-to-Analog converters and Analog-to-Digital converters as well as their associated analog circuits. It all translates to better sound for the price, the company says.
The front-end consists of the stereo portion of a Sigma SSP, including inputs for USB types A and B, Ethernet for streaming AirPlay and DLNA, coax, optical, analog inputs for XLR and RCA and an optional phono (as in the CP-800 and Sigma SSP). Classé has also included 4 HDMI inputs, adding convenience for users with AV sources like set top boxes and Blu-ray players. The Classé touchscreen control provides familiar features like digital domain Tone Control, 9-band PEQ per channel and flexible bass management. The subwoofer output is derived from the only DAC on board. IP control includes Android and iOS apps.
The amplifier section consists of the power supply, DSP and amplifier circuitry of an AMP2, making this a seriously powerful, high resolution integrated amplifier. The Sigma 2200i uses a 3U tall chassis that occupies the same footprint as all of the other Sigma models. The extra 1U space on the lower third of the faceplate contains an air intake. A small Noctua fan mounted to the rear panel spins quietly at low rpm to gently draw air through the chassis, keeping the circuitry at a comfortable operating temperature while extending the life of the electronic components.
Announced retail price for the Sigma 2200i is $5,500 (for the US market) and the new amp will be available May 2016.
