Goldmund Telos 800 Stereo Power Amplifier

Goldmund Telos 800 Stereo Power Amplifier

The Goldmund Telos 800 is a high-end stereo power amplifier designed and manufactured in Switzerland. It delivers 300 watts per channel into 8 ohms using Goldmund's proprietary Telos® Class A/B amplification technology, offering exceptional control, dynamic range, and transparency across the full frequency spectrum.

Position in the Goldmund Lineup

The Telos 800 represents Goldmund's entry point in their current power amplifier range, positioned below the Telos 2800 monoblock amplifiers and the flagship Telos 8800 monoblocks. Despite being the starting model, it shares the same Telos® amplification technology that has defined Goldmund's sound since the 1990s. For listeners seeking Goldmund's signature performance without the complexity of separate monoblock chassis, the Telos 800 offers a compelling single-box solution. Goldmund recommends pairing it with the Mimesis Signature preamplifier and Tethys loudspeakers for an optimized system.

Telos® Amplification Technology

At the heart of the Telos 800 is Goldmund's Telos® amplifier technology, first introduced in the 1990s and continuously refined over the decades. Operating in Class A/B, the design employs highly linear analog components combined with a high-bandwidth circuit that extends from 0Hz to over 1MHz. This approach enables precise speaker driver control, delivering clean power while preventing the unwanted noise and distortion that can compromise signal integrity. The technology particularly excels in low-frequency reproduction, where greater woofer diaphragm movement typically increases the risk of distortion and unwanted vibrations.

Speaker Control and Damping

The Telos 800 achieves a damping factor of 600 at 1kHz into 8 ohms. By drastically lowering output impedance, the amplifier enhances micro-dynamics and prevents large woofer overshoots during high-power conditions. This results in controlled, articulate bass without the loose or boomy characteristics that can plague less capable amplifiers driving demanding speaker loads.

Power Supply Design

The amplifier incorporates a redesigned power supply unit featuring a substantial 3,200VA toroidal transformer and an impressive 93,600μF capacitor bank. These reserves ensure stable power delivery regardless of the demands placed on the amplifier. The smooth transient response between low and high volume levels enhances dynamic range and allows the Telos 800 to handle rapid volume changes with precision. The capacitor power banks were specifically tailored for stereo amplification, differentiating this model from its monoblock siblings.

Measured Performance

The Telos 800 achieves distortion figures below 0.05% across both IMD and THD+N measurements, with an output noise floor below 3 microvolts from 20Hz to 20kHz. The 110dB dynamic range ensures the amplifier captures both the subtlest musical details and the most demanding crescendos without compression or strain. These specifications translate to an amplifier that maintains transparency and clarity whether playing at whisper-quiet levels or full concert intensity.

Connectivity

The rear panel offers comprehensive connection options for integration into various systems. Analog inputs include both balanced XLR and unbalanced RCA pairs, while a digital RCA input and output enable connection with Goldmund's digital preamp/processors. Speaker connections are provided via four binding posts and two Goldmund proprietary 4B connectors. An RS232 port enables remote control and system integration. The inclusion of a ground/earth lift switch helps eliminate ground loop issues in complex system installations.

Mechanical Design and Construction

The Telos 800's chassis reflects Goldmund's belief that mechanical design directly impacts sonic performance. The ultra-thick enclosure is crafted from a micro-blasted aluminum alloy, resulting in a smooth, silk-like finish. Seamless assembly with no visible joints and minimal external screws ensures both structural integrity and visual elegance. Beyond aesthetics, the mechanical design addresses critical technical requirements including heat dissipation, mechanical grounding, and electromagnetic shielding.

Mechanical Grounding™

The amplifier employs Goldmund's proprietary Conic Feet, designed according to their Mechanical Grounding™ principles. These feet evacuate unwanted vibrations to the ground, preventing resonance buildup within the chassis that could otherwise color the sound or compromise signal integrity.

Finish Options

The Telos 800 is available in Goldmund's signature silver-gray finish as standard. A black matte version is available on demand, subject to stock availability and variable lead times. For personalization, the silver-gray ring on the top left of the front chassis can be replaced with a gold ring on special request.

Testing and Quality Control

Every Telos 800 amplifier undergoes rigorous objective testing and subjective listening evaluations before leaving the Goldmund facility in Switzerland. The company validates both measured specifications and real-world listening impressions, ensuring each unit delivers the sonic purity the brand is known for. Goldmund emphasizes that unlike conventional amplifiers that may perform well with resistive loads in laboratory conditions but falter when driving real-world passive speakers, their amplifiers maintain consistent performance in both scenarios.

Critical Reception

The Telos 800 has garnered significant attention from the audio press since its introduction. Alan Taffel, writing for The Absolute Sound, described the amplifier's presentation as "vivid" and noted that "the scale and density of musical and sonic information is unsurpassed." The amplifier received a 2025 Golden Ear Award from the publication.

Summary

The Goldmund Telos 800 represents the Swiss manufacturer's commitment to delivering reference-level amplification in a stereo chassis format. With its Telos® technology, robust power supply, comprehensive connectivity, and meticulous Swiss construction, it offers a compelling alternative to monoblock configurations for audiophiles seeking the highest levels of performance combined with practical single-chassis convenience.
