Rolling Back The Years : Classé Delta Mono Power

Ιn spite of the times, Canadian Classé presents new Delta MONO MOSfet twin Power Amplifiers.. Canadian Colossus Classé ignores the huge progress and development that has been achieved in the digital amplification field and also the 'green' planet philosophy and proceeds to a classic approach of MOSfets aiming to the old school audiophiles..


classe delta 01


Delta MONO embodies exquisite, controlled, unending power. A perfectly detailed enclosure cradles a highly innovative blend of technologies and hand-selected components which deliver effortless, refined sound.


classe delta 02


Delta MONO is crafted for exceptional performance and durability – every detail superbly refined. The first 35W of power are pure Class A, and with over 300W per unit total (1,000W @ 2Ω) at its command, Delta MONO will confidently control any loudspeaker.Delta MONO delivers the utmost clarity in everything you hear. Every detail communicates natural, authoritative sound. An expansive dynamic range with infinitesimal noise delivers unsurpassed fidelity to the musical source. Start listening.


classe delta 03


Delta MONO continues Classé’s reputation for monumental design. The amplifier creates an immediate presence in any room or installation through its unique form and superb materials. The illuminated VU meter beautifully communicates output with elegance and detail. This is an amplifier that looks as iconic as it sounds.


classe delta 04


Thanks to the unique ICTunnel™ cooling technology, Delta MONO is stackable and rackable in a way no conventionally-cooled amplifier can match. Internal temperature is continuously monitored and controlled, ensuring performance in any configuration. Combined with Delta MONO’s construction, ICTunnel supports a lifetime of unrivalled amplification performance.
