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.
The Evolution Series culminates more than two decades of cutting edge audio design and includes stereo and home theater components that embody 26 years of Krell design and manufacturing excellence. When envisioning Evolution, Krell had a solitary goal - to handcraft a range of components that, simply put, were the best sounding products ever built. The result is a synthesis of almost impossible contradictions; a unique blend of beauty, grace, and the effortless power synonymous with the Krell name.All Evolution Series components are available in diamond-cut silver and a luxurious black finish.The final result of an audio system cannot be better than the signal that it is fed.
The Evolution 505 SACD/CD Player, in an inspired stroke, eliminates a cause of distortion that has plagued digital disc playback from its inception. By taking the nascent analog signal from the DACs and leaving it in its native language, current, the finest musical subtleties and textural shadings are preserved. The result is a perfect analog of the original recording.
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 approaches 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.The Evolution 505 supports SACD (single, dual, and hybrid), CD-R/RW, MP3, and WMA formats.
