Telos 350 - Power Amplifier

The Telos 350 is the latest Goldmund Power Amplifier.

This mono block is built with a new full-aluminum Mechanical Grounding asymmetrical construction. Visually surprising, the asymmetrical effect of having the heatsink on the right side and the weight concentrated on the front right foot proved remarkably efficient and allowed the size and weight of the amplifier to be seriously reduced without quality loss. This design also makes it easily stackable.

The internal circuit is seriously improved over the previous Telos and largely inspired by the recent Telos 5000, Goldmund masterpiece. Using the same type of capacitors, a revised input circuit and no less than an Alize 6 D/A circuit, the only sacrifice on the Telos 350 is the suppression of the analog level control. Its approximate 3dB steps are rendered unnecessary by the easy adjustment to the half dB inside a Goldmund universal preamplifier.

To improve the peace of mind of clients who use several Telos 350, its protection circuitry is the most advanced of any Telos amplifier so far; it makes it perfectly safe in case of short-circuit and many other typical electrical incidents.

The Telos 350 real power will remain undisclosed… But the company says it will be much more powerful than a Telos 400 despite its reasonable price. Knowing that the Telos 600 has been recently discontinued, it may be concluded that it can drive quite anything.

In addition, the Telos 350 is the first amplifier that can be mixed with the existing Telos 2500, Telos 1000 or Telos 600 in a Proteus configuration, providing a substantial economy on large Proteus systems such as the Full Goldmund Epilogue. The Telos 350 can drive its tweeters and even the Epilogue 1 Signature woofers.

Last, but not least, the Telos 350 provides an internal connection for an optional pluggable DSP board, just like the U-Telos amplifiers of the Goldmund Media Room. Connectable to a laptop by an USB connector, the future DSP board will allow Amplitude, Phase and Delay to be adjusted to set the Telos 350 in any configuration, including a complete Media Room environment.
