About the Telos 2500

The Goldmund Telos 2500 is a mono (monoblock) universal power amplifier designed for high‑end audiophile systems, delivering very high output power with extremely wide bandwidth and low distortion. It provides continuous power of 400 W into 8 Ω, 4 Ω, and 2 Ω with dynamic power up to 600 W into 8 Ω, and a specified minimum load impedance of 1 Ω, making it suitable for demanding loudspeakers. Total harmonic distortion is specified at 0.01%, with a frequency response of approximately 1 Hz to 300 kHz (Goldmund’s own literature and major databases also quote 0–300 kHz ±0.1 dB and extension to 800 kHz ±1 dB). The amplifier offers RCA and XLR analog inputs, high signal‑to‑noise ratio (around 130 dB), and is built as a very heavy, mechanically rigid chassis weighing 75 kg. Physical dimensions are given as roughly 460 × 515 × 325 mm (W × D × H) in some manufacturer‑linked documentation, and 460 × 325 × 510 mm in other reputable listings; both sets of figures describe a large, full‑size Goldmund chassis of the same weight and layout. Protection circuits include standard Goldmund implementations for overload and thermal protection, but are not marketed as “digital I/O” or networking features. The original Telos 2500 is a pure analog power amplifier; the Telos 2500 NextGen / NG is a later, distinct model with different specifications: maximum power 365 W into 8 Ω (IEC60065, 1% THD), bandwidth specified 20 Hz–20 kHz ±0.03 dB, THD+N <0.05%, damping factor 600 at 1 kHz / 8 Ω, and RCA/XLR analog inputs plus RS‑232 control, in the same 75 kg chassis. Claims of 1000–1200 W per channel, 0.005% THD, and extensive digital inputs and outputs correspond to non‑Goldmund “reference” products or clone amplifiers, and do not apply to the genuine Goldmund Telos 2500 or Telos 2500 NextGen.
