Sigma 2200i


2200frontThe Sigma 2200i Stereo Integrated Amplifier is designed for music lovers and AV enthusiasts who want high performance control and amplification from a diverse range audio sources.

Its connectivity and processing power accommodate the ever increasing array of music and AV sources, allowing them to be accessed and enjoyed without compromise.

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).

Classe Audio has also included 4 HDMI 2.0 inputs with HDCP 2.2 on one input.

The availability of HDMI switching adds convenience for users with AV sources like set top boxes, Blu-ray players, etc.

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 onboard. IP control includes iOS and Android 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.


It is capable of effortlessly driving virtually anything on the market including all of the new 800 Series loudspeakers.

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.

The unique rack-mount solution introduced in the original Sigma series models, contained in the design of the side panels, is retained in the Sigma 2200i.

Simply remove the sides, rotate and flip them, then reattach to position rack ears for rack-mounting.

The convenient and efficient Sigma series package is ideally suited to a stereo integrated amplifier.

Performance, connectivity, unique features and loads of power are available at a compelling price. That’s Sigma, it’s what Classe Audio do.

Classé Audio

Classé Audio “There has to be something better.” These were the words of Mike Viglas in 1979, sending him on a path to partnership with engineer David Reich and the founding of Classé Audio. Mike knew what it was to work hard and build things. A Greek immigrant, Mike arrived in Montréal, Canada as a young man with little money but plenty of energy and determination. He was welcomed by French-Canada and embraced it in return. Opportunities arose wherever Mike made them and year after year he built on his successes. Winters in Florida and summers in Canada, Mike was comfortable, living the good life. Mike was passionate about many things, especially music. His hi fi system was truly high-end and he loved showing it off at parties. While no one could believe that a stereo could cost so much, everyone agreed it sounded amazing. Then the inevitable happened. BOOM! Lights flickered, silence, a strange odor permeated the room and particles, formerly contained within his beloved vacuum-tubed amplifier descended. As the guests pulled capacitor wadding from their hair, Mike, embarrassed, vowed that it would not happen again. There had to be a better way. The problem is common even today. How to get both performance and reliability from high-end electronics? This was top of mind when Mike met David Reich, a talented young engineer building his own solid-state amplifiers. Mike was instantly taken with the sound of David’s amp and together they set out to realise that vow. Classé was founded. Their first amplifier, the DR-2, was introduced in 1980. It was a 25W stereo amplifier operating in class A, which inspired the name of the new company. Other models followed and Classé quickly earned a reputation for both reliability and its open, natural, authoritative sound. Forty years on, Classé remains at the forefront of audio. The iconoclastic and talented Classé Design team in Montréal now has a global reach, being larger and more diverse than ever. Precision manufacturing at the legendary Shirakawa Audio Works in Northern Japan allows today’s Classé to deliver on the performance and reliability always demanded by Mike Viglas. "We think he would be proud of what we have achieved. Dave Nauber Brand Director – Classé"
