5 Channel Power Amplifier. Their newest Delta series amplifiers embody all that Classé represents:
innovation, technological achievement, consummate craftsmanship, and iconic design. But they are not just the latest in the distinguished line of Classé amplifiers to be launched since 1980. They are new,revolutionary and unique.

Performance first
The original Delta series amplifiers won more than critical acclaim. Elite audio professionals use them to master music and movies that the whole world has enjoyed. Their newest amplifiers are even better. Objectively, pure technical measurements prove they deliver our highest
performance ever. Subjectively, they simply blow audiences away.

The Classé design team has created the ultimate environment to amplify an audio signal. The entire amplification process occurs on a single board, creating the most direct and transparent signal path conceivable. Their uniquely miniaturized driver stage is virtually noise
free, so every nuance of the original signal reaches the output stage.

Here, vast quantities of clean power are controlled with absolute precision. Suddenly, the world’s finest speakers sound even better.

Performance fast
There is a relationship between temperature and performance but it is widely misunderstood. Audiophiles say that optimal performance is obtained when an amplifier is “warmed up,” but what does this actually mean? When is it warm enough and when is it too warm?
The exposed heatsink fins found on conventional amplifiers are passive. They can’t help circuits reach their ideal temperature or keep them there throughout a listening session. They run at a temperature wholly defined by their environment and how loud they are playing. This can be far from ideal.

Heat management in Classé’s new Delta series amplifiers is provided by the ICTunnel™ (pronounced Icy Tunnel), a sensor- and microprocessor- controlled technology inspired by the heatsinks found in high-power laser and medical equipment. Mounted inside the unit, the ICTunnel™ actively regulates the amplifier temperature to ensure both optimum performance and reliability.

From room temperature, the amplifiers warm up fast. They reach their ideal temperature in less than fifteen minutes and remain there regardless of how hard they are driven. No conventional heatsink can do this.

In a Class by itself
Ground-breaking performance, prodigious power, sophisticated control and rock-steady reliability—Classé’s new Delta series is a giant leap in amplifier design. Thanks to exclusive ICTunnel™ and audio technologies,
only Classé amplifiers can consistently deliver top performance and reliability in every installation.

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.
