TechDAS D-7 Precision Digital Interface

Stellavox Japan, a major audio distributor in Japan, has released its own line of product of which the TechDAS D-7 DAC, priced at approximately US$3,000 in Japan, would be the first of this new line. There will also be another version, the D-7i, which has direct iPod connections. 

The D-7 sports a Wolfson DAC chip (up to 24/192), and the galvanically isolated USB connection is of asynchronous type. Adjustable upsampling rate (1x, 2x, 4x) accessible from the front panel.  So via digital output, the unit can be used as an asynchronous USB to S/PDIF converter, and also asynchronous sample rate converter. Unit seems to be very well-made and styling is clearly influenced by Goldmund SRM models from the 1990s, of which the company has close relationship with.

• Digital input RCA, Toslink, USB (up to 24/96)
• USB host port for USB drives
• RCA digital output
• Word clock input
• Fixed analog output (RCA and XLR)
• Adjustable analog outputs (RCA)
• Headphone amplifier

Future enhancements would include upgraded USB input to allow for 192kHz sample rate and possibly a LAN network support.
