Krell Evolution 505

Evolution 505 FEATURES
Matched 24-bit /192 kHz DACs are used on all channels, and the left and right output circuitry provides CAST and balanced connections for optimal stereo playback.

Surface Mount Technology, a state-of the art circuit miniaturization technique, provides the circuit density and signal transfer capability demanded by the advanced Krell circuit design employed in the Evolution 505.

The current output signal of the DACs is fed directly to the Krell Current Mode audio circuitry eliminating the deleterious effect of the current-to-voltage conversion stage present in all other designs.

Evolution circuit topology breaks through bandwidth limitations of conventional designs resulting in near perfect performance in the audible range.

A complete Evolution (source, preamp, amplifier) system, connected in CAST, reduces the number of voltage gain stages to the minimum, one. The resulting noise floor is approaching the theoretical limit of technology.

Power supply makes use of extensive electrical and magnetic shielding to keep radiated interference out of critical audio circuits.

Separate power for drive mechanism, digital and analog circuitry maximizes the performance of all sections. A custom-wound toroidal power transformer, 10 times larger than those found in typical source units, offers tremendous current and low noise operation for the analog circuitry. Several stages of regulation insure rock steady power to all gain stages for maximum dynamic impact.

Evolution 505 supports SACD (single, dual, and hybrid), CD-R/RW, MP3, and WMA formats.
