The Classe Delta Stereo Amplifier is an anodised aluminium stereo power amplifier engineered to deliver reference-grade control in dedicated two-channel audio systems. Operating in pure Class A for the initial 12.5 watts before transitioning seamlessly to Class AB, the chassis delivers 250 watts per channel into 8 ohms and up to 500 watts into 4 ohms. This architecture provides high-fidelity listeners with the natural harmonic warmth of low-power Class A topologies alongside substantial reserve current for demanding speaker loads.The Hi-Fi Centre Team TakeLiving with the Classe Delta Stereo reveals an effortless authority that remains calm even across the most complex musical passages. The illuminated analogue VU meters provide practical visual feedback in darkened rooms, while the internal thermal management keeps the unit running silently during extended evening sessions. Its massive foundation delivers tight, articulate low frequencies that anchor your listening space without inducing acoustic fatigue.Key Acoustic & Design Features Class A Output: Delivers twelve and a half watts of initial Class A operation to preserve subtle acoustic nuances and tonal warmth. Mundorf Power Reservoir: Integrates twenty-two four-pole capacitors with a toroidal transformer to maintain immediate current delivery into low-impedance loads. Vibration-Decoupled Chassis: Employs dense internal circuit topology and custom Navcom isolation feet to protect micro-dynamics from mechanical resonance. Authorized Dealer Assurance: Guarantees authentic factory warranty coverage and long-term technical support directly through Hi-Fi Centre. Technical Specifications Product: Classe Delta Stereo Amplifier Type: Solid-state stereo power amplifier Pure Class A Power: 12.5 W per channel (8 ohms) Continuous Power Output: 250 W per channel (8 ohms), 500 W per channel (4 ohms) Frequency Response: 1 Hz – 650 kHz (-3 dB) Total Harmonic Distortion: < 0.0016% at 1 kHz Signal-to-Noise Ratio: 118 dB Binding Posts: Furutech rhodium-plated terminals Dimensions (W x D x H): 444 mm x 492 mm x 222 mm Net Weight: 46.4 kg (102.3 lbs) Frequently Asked QuestionsWhat is the sonic advantage of operating in pure Class A for the first 12.5 watts?Class A operation eliminates crossover distortion entirely, delivering natural harmonic richness, fluidity, and tonal purity during typical listening levels. When dynamic headroom is required, the amplifier transitions seamlessly into Class AB to handle transient peaks effortlessly.How does the amplifier manage heat during extended listening sessions?The Delta Stereo incorporates Classé’s proprietary ICTunnel active cooling technology. A low-noise, microprocessor-controlled fan brings the internal components to their optimal operating temperature rapidly and maintains silent, stable thermal equilibrium, even when positioned in enclosed cabinetry.Can the Classe Delta Stereo comfortably drive difficult, low-impedance loudspeakers?Yes. Thanks to its massive toroidal transformer and high-capacity Mundorf power reservoir, the Delta Stereo doubles its output from 250 watts into 8 ohms to 500 watts into 4 ohms, maintaining unconditional stability and vice-like control over complex, low-impedance loads.
