Evolution 505 Features and Technology

This section describes the innovative features and technology of the Evolution 505 SACD/CD Player, and defines CAST and other key terms used in this reference.

The Evolution 505 works to carefully transmit audio signals without damaging the ephemeral staging and dimensional components of the music. A combination of advanced technologies and inspired design elevate the Evolution 505 SACD/CD Player’s performance to the reference level.

Features

The Evolution 505 has Class A, balanced, Krell Current Mode topology from input to output for increased bandwidth. New current mirror stages feature LED voltage reference. Developed for the Evolution Two, these current mirrors operate with three times less distortion than previous designs. A zero feedback design pre- serves the original harmonic structure of the recording, and a 500 K bandwidth promotes low distortion and phase coherent performance.

The Evolution 505 uses PCM 1738 differential advanced segment DACs for supe- rior dynamic range, and a DCI drive with independent suspension for enhanced ergonomics and reliability.

The Evolution 505 will read redbook, CDR, 44.1 WAV, AAC (adts, and adif), DVD- R, RW, +R, and RW discs. The 16 character, dot-matrix LED display is highly visi- ble and features an adjustable intensity.

For flexibility of control, the back panel features a 2-way, RS-232 interface, an RC-5 connector, and 12 VDC trigger inputs and outputs. Krell Can Link connec- tors allow the Evolution 505 to operate in link mode with other Evolution compo- nents.

The outputs include balanced XLR, single-ended multi-channel outputs, and a pair of Evolution CAST™ outputs, for the most robust connection to other Evolution components.

A 65 VA linear power supply is used for the drive mechanism, for absolute voltage stability. A separate 45 VA linear power supply for the audio circuits is optimized to power critical Class A audio topologies.
