Experience the effortless magic of absolute authority. Vocalists and instruments materialize within an astonishingly concrete sound stage. From the most delicate solos to thundering orchestrals, emotion and music dance throughout a seemingly infinite frequency spectrum.
The Model 825 represents the ultimate benchmark of dynamic realism and expressive refinement. A quarter century of engineering passion expressed in the synergy of advanced technologies and timeless design. A stunning achievement inspired by the musicality of an enduring classic: the Rowland Model 8.
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.
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.
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.
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, 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.
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 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.
Power Factor Correction (PFC) in the power supply reduces AC line harmonic noise pollution and increases AC line power utilization to 99%.
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.
