Sforzato DST-01 Digital Stream Transport


And you think the Linn streamers are over the top? Extreme attention to detail, the Japanese made two-box Sforzato DST-01 upsampling Digital Stream Transport is a DLNA enabled streamer which connects to a Network Attached Server or PC over LAN network. Ultra-low jitter temperature controlled crystal oscillator to control the master clock.  Large toroidal transformers, with separate supply to digital processing and other circuits.  Each transformer is placed coaxially with leg spikes provide grounding of external vibration.  Front panel switch selects up-sampling rates of up to 192kHz with various digital filters settings (standard, no pre-echo, no post echo, minimum phase, etc.) which happens before sending digital signal to an outboard DAC.  Please note that the second box is the power supply, not the DAC. Sforzato is also developing a dedicated DAC for it which is going to be called the DSR-01 (DigitalStream Renderer).  Controls are done through iPod or iPhone using the included MLPlayer app.
