Goldmund Telos 2800

Goldmund Telos 2800 Mono Power Amplifier

The Goldmund Telos 2800 is a Swiss-made mono power amplifier delivering 450 watts into 8 ohms through Goldmund's proprietary Telos® Class A/B amplification technology. Replacing the Telos 2500 NextGen, it represents a significant advancement in power supply design and thermal management while maintaining the exceptional sonic characteristics that define the Goldmund sound.

Position in the Goldmund Lineup

The Telos 2800 occupies a position above the Telos 1800 (420W) in Goldmund's mono power amplifier hierarchy, offering increased power output and an even more substantial power supply architecture. It sits below the flagship Telos 8800 and Telos 4800 models, providing serious audiophiles with reference-level mono amplification capable of driving virtually any loudspeaker to its full potential. For stereo applications, a pair of Telos 2800 amplifiers delivers dedicated mono amplification for each channel with completely separate power supplies.

Telos® Amplification Technology

At the core of the Telos 2800 lies Goldmund's proprietary Telos® amplification technology, a meticulously engineered Class A/B circuit that fuses the linearity of analog components with high-bandwidth architecture. By refining the linearity of every amplification stage, Telos® technology virtually eliminates harmonic and intermodulation distortion, both measuring below 0.05%. The high-bandwidth circuit minimizes group delay distortion, ensuring impeccable timing and sonic coherence across the audio spectrum.

Speaker Control and Signal Purity

Goldmund's Telos® amplifiers deliver pure power with absolute precision, ensuring the integrity of the audio signal is never compromised. Proper driver control allows for impeccable sound reproduction free from distortion and unwanted artifacts. This is particularly crucial for low frequencies, where woofer diaphragms often suffer from excessive motion leading to unwanted vibrations. A sophisticated output impedance reduction system enhances micro-dynamics, controls excessive woofer overshoot in high-power conditions, and eliminates unnaturally "boomy" bass. The 600 damping factor at 1kHz into 8 ohms ensures firm control over connected loudspeakers.

Redesigned Power Supply

The Telos 2800 surpasses its predecessor with an entirely redesigned power supply system. At its heart lies a robust 3,200VA toroidal power transformer, enhanced in size and power to deliver even more output in the same chassis footprint. This is complemented by a colossal capacitor bank of 109,600μF, featuring custom Goldmund-branded capacitors engineered to improve the amplifier's dynamics and reactivity. These enhancements ensure seamless transient response between high and low sonic levels, improving dynamic range and allowing the amplifier to handle rapid volume shifts with absolute precision without distortion or saturation.

Advanced Thermal Management

The Telos 2800 introduces significant improvements in heat dissipation. A new CNC-machined heat sink covers the entire rear panel of the amplifier, creating substantially more surface area to dissipate heat generated by the power supply. This full-panel radiator design, combined with the 10-12mm aluminum chassis panels and 30mm-thick side radiators, ensures optimal thermal management even during extended high-power listening sessions, all achieved through silent passive cooling without fans.

Circuit Architecture

Goldmund's advanced circuit architecture separates high and low-current circuits to prevent feedback and interference, ensuring pristine audio transmission. The integration of Mechanical Grounding™ technology efficiently channels vibrations directly into the ground, eliminating unwanted resonances that could otherwise color the sound. Despite its 450-watt output capability, the Telos 2800 delivers flawless performance from the very first watt, whether reproducing a delicate piano passage at whisper-quiet levels or a full-scale orchestral crescendo at concert volume.

Real-World Performance

Goldmund emphasizes that many amplifiers excel under ideal laboratory conditions with resistive loads but struggle when driving real-world passive loudspeakers with complex impedance curves. The Telos 2800's engineering goes beyond traditional benchmarks, ensuring flawless technical performance in both scenarios. The amplifier brings music to life exactly as it was intended, faithfully translating every nuance of the audio signal.

Connectivity

The rear panel provides comprehensive connection options. Signal inputs include both balanced XLR and unbalanced RCA connectors, accommodating virtually any high-end preamplifier. Digital RCA input and output connectors enable integration with Goldmund's digital processors. Speaker connections include two binding posts and a Goldmund 4B proprietary connector. A DB9 serial connector enables system integration and remote control, while separate grounding and earth binding posts with a ground lift switch address complex installation requirements.

Chassis Design and Construction

Every aspect of the Telos 2800 represents a fusion of high-end engineering and aesthetic mastery. The seamless aluminum chassis is crafted from precision-machined, micro-blasted aluminum, delivering exceptional structural integrity and understated elegance. The joint-free design exemplifies refined minimalism. Panel thickness has been upgraded to 10-12mm (from the previous 6-8mm in earlier generations), significantly improving enclosure rigidity, mechanical grounding, and vibration dispersion capabilities. Sculpted wavy sides echo Goldmund's latest design language, lending the unit a mineral-like aesthetic.

Electromagnetic Shielding

The solid aluminum structure acts as a fortress against electromagnetic interference, ensuring an undisturbed, ultra-pure signal path. This natural Faraday cage protection is particularly important in systems where the amplifiers may be positioned near other electronic equipment.

Mechanical Grounding™

The Telos 2800 incorporates Goldmund's Conic Feet technology, a crucial component of their Mechanical Grounding™ system. These precision-engineered feet direct vibrations into the ground, preventing resonance buildup within the chassis. Combined with the heavy-weight structure and resin-coated transformers that minimize mechanical and electronic vibrations, this approach ensures stability and sonic purity.

Quality Control and Craftsmanship

A Goldmund amplifier is more than an audio component; it is a work of art, designed, engineered, hand-assembled, and meticulously configured piece by piece. Every internal component is individually tested for optimal performance before assembly, and every completed unit undergoes final testing to meet Goldmund's uncompromising standards. With over 45 years of expertise, Goldmund continues to push the boundaries of high-end audio technology. Unlike mass-produced equipment, Goldmund amplifiers are handcrafted in Switzerland by a team of highly skilled artisans and engineers.

Finish Options

The Telos 2800 is available in Goldmund's signature silver gray finish as standard, with a black finish available upon request. For the Chinese market, a distinctive gold accent ring graces the top panel, while international models feature a tone-on-tone gray ring for a unified, sophisticated appearance. The accent ring can be specified to match aesthetic preferences.

Summary

The Goldmund Telos 2800 represents a milestone in high-fidelity audio, combining extraordinary power output with the refinement and precision that define the Goldmund sound. With its redesigned power supply featuring a massive transformer and capacitor bank, advanced thermal management, premium construction, and meticulous Swiss craftsmanship, the Telos 2800 delivers an uncompromising listening experience for the most demanding audiophiles. It redefines the standards of sound quality and precision in mono power amplification.
