Description
Dual-mono power, absolute control and refined musicality
The Classé Delta STEREO is a two-channel power amplifier designed with dual-mono architecture to ensure superior channel separation, dynamics and control. The first 12.5 W in Class A ensure naturalness and micro-detail, while the power section delivers 250 W into 8 Ω and 500 W into 4 Ω , with stability and authority even into demanding loads. The fully balanced topology, oversized power supply and reference-grade mechanical construction make this amplifier ideal for high-end stereo and high-profile home cinema systems.
Delta Architecture: Silence and Absolute Precision
The Delta platform uses optimized signal paths and selected components for extremely clean and transparent results. Multilayer circuit boards, a fully balanced output stage, and an extended frequency response up to 650 kHz contribute to fast and controlled reproduction. The 116 dB signal-to-noise ratio, low THD+N , and high damping factor ensure background silence, controlled low-end, and great dynamic articulation.
Professional integration and advanced thermal management
Delta STEREO is also designed for advanced installations thanks to ICTunnel™ cooling technology, which allows flexible configurations (even in racks) while maintaining optimal operating temperatures. Connectivity includes balanced XLR and unbalanced RCA inputs, high-current Torque-Guard speaker binding posts and control functions such as DC Trigger , IR , RS-232 , Ethernet and CAN-Bus . The iconic aesthetic with central VU meter completes a project that combines performance and design.
