        Benefits of Jeff Rowland 825 Stereo Power Amplifier: 

        Machined Aluminim Chassis
        Machined Aluminim Chassis

        Precision-machined chassis with integrated heat-sinks, milled from a solid block of aircraft grade aluminum, provides exceptional thermal heat transfer/dissipation, RFI/EMI shielding, and resonance control.

        Ceramic Circuit Boards
        Jeff Rowland 825

        All audio circuits are implemented on mil-spec, multi-layer, low dielectric constant, RogersTM ultra-rigid ceramic circuit board substrate for extremely low energy retention and absorption. Large low impedance ground planes areas for extended internal star-grounding.

        Composite Circuit Architecture

        Unique composite circuit architecture incorporating separate Class AB voltage and current gain blocks with no overall negative feedback, delivers a sensuous grain-free musicality of unparalleled transparency and low level resolution.

        Balanced Topology

        Inherent cancellation effects of balanced topology implemented throughout all power and input/output circuits ensures greatly reduced distortion and noise under dynamic signal conditions.

        High-Current Copper Bus-Bars

        High-current, dual polarity, ultra low impedance copper bus-bars distribute both power supply input current and signal output current, virtually eliminating intra-circuit EMI signal contamination, greatly reducing internal wiring, while increasing circuit board rigidity.

        High Precision Surface Mount Components

        Extensive use of Lead (Pb)-free, low temperature coefficient, active and passive surface-mount components results in significantly smaller loop areas, reduced circuit capacitance and inductance, and introduces less noise than conventional leaded components.

        Transformer-Coupling and Isolation

        Transformer coupled input circuitry provides universal component compatibility and virtually eliminate ground loop noise and RFI/ EMI. Transformer coupling ensures identical amplifier overall gain when using unbalanced input adapters.

        High-Efficiency Switch-Mode Power Supply

        Highly efficient, compact, light weight, 1500 watt DC switch-mode power supply provides optimum voltage regulation for all circuits and operating conditions, and allows for quiet operation over a wide range of AC mains power sources.
