Analog Power Amplifier
The Telos 380 mono amplifier belongs to the long lineage of power amplifiers introduced for the first time by Goldmund in 1982. Today’s schematics have been patiently refined by several generations of engineers, each one making it even closer to perfection.
The original goal of the Goldmund amplifier design is to deliver much better “Speaker Control” – or “Acoustical Damping” in Goldmund terms – than any other existing designs. This means minimizing any parasite noise added by the amplifier to the signal it receives from the source and transfers to the speakers. In the design of a power amplifier, Speaker Control is improved by a sum of specific amplifier properties, some kept secret.
Each generation of Goldmund power amplifiers has been capable, progressively, of better Speaker Control, achieving in 2020 a control over 100 times better than the original 1982 design. For this reason, many unpowered speaker manufacturers are using Goldmund power amplifiers in their private demonstrations.
