Telos 5500 NextGen

Telos 5500 NextGen - Усилитель мощности

Extreme, powerful and majestic, the New Telos 5500NextGen is the heir to the Telos 5000+, an engineering prowess of the highest technical level. The major improvements brought to this unit represent such a significant step in audio amplification, that they will shape the next generation of high-end amplifiers, whether separate or built-in.

The Telos 5500NextGen new power supply makes it even more powerful than its predecessor, the Telos 5000. It is built with a 6400 VA transformer block, 360.000 uF reservoir capacitors, and 72 output transistors to provide extreme power reserves. It also includes gold plated brass conductors instead of PCB’s.

Its input stage is completely different. With its XLR connector, it is fully balanced but also offers unbalanced analog and digital RCA inputs. The input circuit was enhanced to allow silent switching and guarantee the stability when input mode and level are changed.

The amplifier security has been considerably perfected in order to protect precious drivers from the extreme power the amplifier can deliver.

A gain selector in the back of the unit allows to precisely fine tune the system in which it is installed and a low pass frequency cut off control provides three different settings to customize the amplifier.

The input selection is made thanks to its RS232 port that also allows the connection with a Crestron or other home automation control systems, including the ultra simple Goldmund iPad/iPhone Remote Control.

The Telos 5500 weighs more than 260kg per piece and is housed in an elegant tower measuring 94 x 47 x 39 cm. Two sides are used for the cooling heatsinks and the hard brass construction pushes the Goldmund Mechanical Grounding construction principle to a level never achieved before.

Tests made on the Telos 5500 NextGen clearly show that:

  • The dynamic is excellent and the amplifier is never, even remotely, close to saturation.
  • The control on the drivers is exceptional.
  • The precision of the sound image is just unbelievable with a spacialization that reaches way outside of the speakers, and this without the Goldmund Leonardo time correction! The precision and openness are actually the most impressive of the three characteristics tested.

The Telos 5500NextGen is the amplifier for connoisseurs who want the best of the best in audio reproduction.
