Theta Digital DS Pro Basic III - Digital Processor (DAC)


This is a great vintage processor that's perfect for the audiophile not interested in messing around with HiRes digital content, but wanting the most from the standard (and still excellent) redbook CD.

Tested and working perfectly. Very few signs of use.

Pair this up with the matching Theta Digital CD Transport and special "ThetaLinque" cable also in stock at the time of publishing.

Great sounding hi-end classic by Theta Digital, who were known for "Digital Done Right!" 
• the IIIa was the ultimate version of Theta's legendary DS Pro Basic DAC
 Stereophile recommended component for many years
 designed by Mike Moffat, currently of Schiit Audio
 fully balanced differential signal path throughout the digital and analog domains (i.e., "balanced the hard way" like in Schiit's top-of-the-line Yggdrasil DAC)
 inputs include optical (Toslink), coaxial (RCA), and balanced (AES/EBU XLR)
 outputs include single-ended (RCA) and balanced (XLR)
 the balanced signal is summed at the single-ended output, so you get the benefits of balanced operation from input to output
