Burson Audio Conductor Virtuoso DAC2 PCM1793 DAC and Headphone Preamp With over 4 watts of power on tap the Conductor Virtuoso will drive any headphone with ease. The Conductor Virtuoso's headphone amp section is essentially the Soloist which reviewers have raved about. Or use the Conductor Virtuoso's preamp functions to make it the center of a headphone and speakerbased desktop system with headphone option. There are now a stunning 100steps of volume control with a new, easytoread display. When the Conductor Virtuoso is on the volume indicators appear on the face of the thick, antiresonant aluminium front plate. Sometimes called the Vault by our customers, the 6mm Resonance Free Aluminum (RFA) enclosures are constructed from precisionmachined panels. Eight stainless steel bolts hold the enclosure together so it's virtually indestructible. The RFA enclosures display superior mechanical noise rejection (internal and external) compared to conventionally foldedsteel enclosures used by many audio manufacturers. The enclosure removes any need for big, unattractive heat sink fins and allows our components to be set at a high idle current. The results are lower distortion, higher output and improved dynamics.
