Wadia 381 CD Player
By the Numbers
The 381 utilizes a new CD only transport, modified to allow ClockLinkTM jitter reduction and pure data capture, providing state-of-the-art audio information extraction with the lowest measured error correction in Wadia’s history. Patent worthy technologies ensure that data is accurately captured from audio discs regardless of format, including FLAC. The mechanism is further enhanced by a custom mounting and enclosure system that provides both mechanical and electrical isolation. The result, performance surpassing even the highly acclaimed transports featured in previous players.
Tradition Meets Innovation
Developed for our special edition and reference products, Wadia’s SwiftCurrentTM 3 Discreet (SC-3D) has been combined with the latest version of our superior current to voltage (I/V) conversion technology. Current exiting the D>A converters is optimally loaded, in turn allowing each DAC to remain linear. Current is then mirrored and driven with a zero global feedback Class A throughput stage. The output feeds directly into a phase accurate filter that simultaneously creates voltage and removes unwanted high frequency noise. The SC-3D generates 3 independent data streams that drive both the balanced and unbalanced legs of the output stage. A quieter blacker background ensures holographic images will appear, or in other words the sound stage will be rendered in... 3-D.
The 381 CD Player features two new fully balanced shielded toroidal transformers that are electrically, mechanically, and acoustically isolated from other components. New inductor filtering has been added to the digital supply ensuring smooth charging of capacitors and eliminating noise spikes from the ground plain. There is a fully regulated separate power supply for digital processing, clocking, D>A conversion, and the output stage. Every performance component is powered by regulated isolated power traces. The result – quiet pure power delivered with lightning speed allowing instantaneous reproduction of transient information.
