Wadia S7i CD Player/DAC

Series 7 is Wadia's highest level integrated product series.  Not surprisingly, the all-new CD transport exemplifies series 7 level playback performance.  this exceptional transport was designed in collaboration with the Austrian company Stream Unlimited.  Wadia co-engineered many details of the design, including an application specific servo system optimised for the newest generation of Wadia playback units.

USB for Audiophiles

USB has become an important interface for discerning music lovers, and presents specific technical challenges.  Clock and timing errors are among the most difficult performance barriers when using USB connectivity.  Wadia worked with key component manufacturers to achieve significantly more accurate digital clock information for all USB sources.  By combining optimised clock behaviour with Wadia's proven Digimaster filter topology Wadia provide world class time and phase correct musical output from high resolution USB digital files.  the S7i also provides extremely flexible digital connectivity via AES/EBU, Coaxial/BNC and Toslink.

Power Matters

Multiple fully regulated digital power supplies result in significant noise floor reductions.  There are separate fully regulated power supplies for the C transport/servo, digital processing platform, Wadia's proprietary clock-link network, D>A conversion section, and analog output stage.

The S7i provides flawlessly executed digital signal processing that maintains time and phase coherency, ideally suited for a wide range of high performance systems.

Musicarch view

This is simply one of the most outstanding red-book CD players ever made.  Not only that, but it plays WMA. MP3 and most importantly, FLAC.  The DAC unit is as good as anything we have ever heard.  We have a unit on permanent demonstration connected to a Qsonix 205 music server.
