One of the finest handmade Amplifiers built, designed, and sold in the USA. 

Model 125


The Model 125 stereo bridgeable power amplifier delivers dynamic realism and refinement from its solid aircraft-grade aluminum chassis, a perfect match for the sleek profile of its companion Capri S2 preamplifier.

From a single M125 in stereo mode powering an intimate analog system, up to several bridged units driving a multi-speaker setup, down to a bridged pair controlling demanding 4-Ohm monitors, the energy-efficient Model 125 power amplifier delivers consistent resolution and authority with Rowland finesse.

Custom bespoke audio products from Colorado, USA. 

Features


Machined Aluminum Chassis

Precision-machined from a solid block of aircraft grade 6061-T6 aluminum provides exceptional thermal heat transfer/dissipation, RFI/EMI shielding, and resonance control.

Balanced Topology

The inherent cancellation effects of balanced topology, implemented throughout all power and input/output circuits, ensure significantly reduced distortion and noise under dynamic signal conditions.

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.

Teflon Coated Wires

All signal-carrying input and output wires are Teflon coated for low dielectric energy storage, further ensuring that each audio note reproduced naturally decays into the more profound silence of the music.

Transformer-Coupling and Isolation

Transformer-coupled input circuitry provides universal component compatibility and virtually eliminates ground loop noise and RFI/EMI. Transformer coupling ensures an overall gain of identical amplifiers when using unbalanced input adapters.

High-Efficiency Switch-Mode Power Supply

The highly efficient, compact, lightweight, 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.

Parallel Binding Posts

CE-approved speaker output terminals require no tools for secure low-resist connections and sand allow for easy bi-wiring applications.

Flexible 15 Amp AC Power

15 Amp AC power inlet accepts various after-market high-performance power cables.

Front Panel Standby Button

The illuminated front panel push-button switches the amplifier into standby mode (< 1-watt consumption).

Rear Panel Remote Jack

12V 3.5mm jack on the rear panel permits amplifier power on/standby switching in remote and home theater applications.
