We are proud to offer Tripoint Audio

     Come experience the holographic transportation of the real musical event with our proprietary passive filtration 

component that eliminate EMI/RFI from the signal and impulse signal flow. Hear what your electronics, room, and vibration control really sound like.


Unleash the full potential of your electronics. Listen to music in a more natural, accurate way. At Tripoint we listen to every material that we implement in our circuit to make sure it has the correct resonating frequency that we're looking for. Only after critical listening do we incorporate this into our design. 


Music without Tripoint is nothing more than amplified noise. Once you listen to our approach you too will become a believer.



At TriPoint our ultimate goal is your satisfaction.


     Here at Tripoint we take great pride in each piece that we hand build. We use nothing but the best materials and parts and we listen to every one of them. This is one of the main reasons our voicing is so natural. 


No shortcomings and compromises are taken within our manufacturing process. We believe our design and approach to manufacturing is the only way to achieve our goal.  We hope you share our enthusiasm.


Jeff Rowland Model 825 Stereo Amp

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.

Model 825 Features

Machined Aluminum Chassis

Dual chassis precision-machined from solid bar-stock T-6061 aircraft grade aluminum providing exceptional thermal heat transfer/dissipation, RFI/EMI shielding, and resonance control.

Functional Isolation

The amplifier and power supply are isolated from each other in separate chassis. High-current DC power and low-current control signals are transferred between the amplifier and power supply via custom made detachable cables.

Active Power Factor Correction

Active Power Factor Correction (PFC) in the power supply reduces AC line harmonic noise pollution and increases AC line power utilization to 93%. Voltage and current demands from the amplifier remain in phase with each other which eliminates the transient, out-of-phase, high current pulses common to the operation of all other non-PFC audio power amplifiers.

High-Efficiency Switch-Mode Power Supply

Powerful, efficient, 2500W 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.

Zero-Current Switching

The power supply is comprised of four DC to DC converters incorporating “zero-current-switching” technology for high-efficiency and greatly reduced levels of conducted and radiated noise.

4 pole Capacitors

Custom-made 4-pole capacitors integrated within the power supply further reduce any remaining residual noise.

Noise Isolation

An isolated, discrete component, shunt-regulated power supply, providing over 130 decibels of noise isolation, offers low broadband noise and output impedance. This supplies noise-free DC power to all low-level audio circuitry for battery-like performance.

Solid-State Relay

AC Mains power is switched via a solid-state relay. Switching occurs only during the AC mains zero voltage crossing period dramatically reducing in-rush current during turn-on surges and providing a lifetime of trouble-free switching.

Ceramic Circuit Boards

All input circuitry is implemented on mil-spec, multi-layer, low dielectric constant, Rogers™ ultra-rigid ceramic circuit board substrate for extremely low energy retention and absorption.

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-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.

Thin Film Resistors

All resistors are low-noise, 0.1% thin film Surface Mount Devices (SMD) type for extremely low thermal noise which complements the low-noise characteristics of the active circuitry.

Transformer-Coupling and Isolation

Transformer coupled input circuitry provides universal component compatibility, excellent common-mode noise rejection (CMRR) from the input source, and virtually eliminates ground loop noise and RFI/EMI. Transformer coupling ensures identical amplifier overall gain when using unbalanced inputs.

Rear Panel Controls

Rear panel switching of input phase, overall gain, and input selection (XLR/RCA). A “link switch” permits electrical linking of both right and left channels for bi-wiring applications.

Custom Input Jacks

Both XLR and RCA input jacks are custom-made Cardas connectors constructed of copper, rhodium, gold, and Teflon materials for minimal signal loss and excellent corrosion resistance.

Cutting-edge Output Circuitry

Innovative class-D audio power technology is based upon a non-hysteresis 5th order self-oscillating control loop taking feedback only at the speaker output.

Extremely Low Distortion

Unique output circuitry ensures an extremely low distortion level of less than 0.004% THD + Noise over the entire audio spectrum of 20 Hz to 20 kHz powering any load ranging from 2 to 8 Ohms.

Stability and Flexibility

An output impedance of less than 0.003 Ohms (3 milliohms) over the entire frequency range of 20 Hz to 20 kHz ensures that all loudspeaker types can be driven with impunity. Stability of the amplifier is guaranteed under all conditions when driving any loudspeaker or loudspeaker cable type.

Error Detection

Extensive microprocessor controlled error detection circuitry ensures protection of associated loudspeaker components under many extreme operating conditions.


A power efficiency of 93% at full power output afforded by this technology ensures low energy consumption, low operating temperature, and an extended service life of all components within the amplifier.

Parallel binding posts

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

Flexible 20 amp AC Power

20 amp AC power inlet accepts a wide variety of after-market high-performance power cables.

Front Panel Standby Button

Illuminated front panel push-button switches the amplifier into standby mode. Separate stand-by circuitry reduces AC mains power to less than 1 watt during stand-by, ensuring international regulatory compliance.

Remote On/off

A 1/8” (3.5mm) mini plug connector on rear panel permits amplifier power on/standby switching in remote and home theater applications.

Self-Leveling Supports

Removable 3-point self-leveling Delron chassis supports provide high frequency mechanical noise isolation.

Raidho Loudspeakers


Raidho C1.1 is a small, neatly perfectly proportioned loudspeaker, so in spite of its limited size, the sound it produces is surprising at first, but harmonious at the same time. This model was developed on the basis of recognised theories of dimension, which we put in practice to produce a beautiful cabinet, carried out in every detail, and superbly finished. C1.1 is put together from hand-made units built from Raidho’s patented technologies.

The two-piece baffle is made from 20mm aluminium with each driver assembled directly onto its rear face.

The C1.1 is a new breed of small loudspeakers that uncompromisingly let you hear what your system and the musicians can do. Simply listen to a Raidho C1.0 for an impressive experience. Please read more about the difference between the C-1.0 and C-1.1 on the link " inside "
