The TELOS 670 is an integrated stereo amplifier from Goldmund, a Swiss manufacturer renowned for uncompromising, fully active loudspeaker and electronics engineering. The TELOS 670 brings that considerable engineering ambition into a complete integrated chassis combining preamplification and power stages.
Key specs that matter
Five single-ended inputs are provided. Output power is 2 x 250W into 8 ohms, a substantial figure for an integrated amplifier. Gain is 35dBu. Total harmonic distortion plus noise is held under 0.08%, with an exceptionally high damping factor of 600 - a remarkable figure indicating outstanding control over connected loudspeaker driver movement, considerably higher than most rival integrated amplifiers achieve. At 440 x 160 x 395mm and 24.5kg, the TELOS 670 represents a substantial integrated amplifier commitment.
Sound and use context
Expect exceptional control and precision reflecting the remarkable damping factor of 600 - Goldmund's characteristic attention to genuine grip over loudspeaker drivers is fully evident even in this integrated, single-chassis format, translating flagship-tier control into a more consolidated system solution.
Pairing
The exceptionally high damping factor suits demanding, revealing loudspeakers directly, and the five-input connectivity comfortably covers a source-rich system without needing an external switcher.
Alternatives
Goldmund's broader amplifier and fully active loudspeaker catalogue offers alternatives for buyers wanting either a more elaborate separates-based system or Goldmund's fully active loudspeaker philosophy instead of this integrated solution.
