Non Oversampling (NOS) DAC's


Been investigating NOS DAC’s of late, and I’ve been pleasantly surprised at their performance.

For example, recently picked up an Oritek Audio NOS DAC second hand just to see what the NOS sound had progressed over the years. The more I listened to it, the more it sounds pretty musical to me. Not having heard them for a long time, one would have thought that NOS DAC’s would have been lacking in smoothness and detail compared to the plethora of oversampling DACs available, but that may not be the case. The Oritek sounds more like a master tape than most of the DAC’s I’ve heard at its price point.

This DAC has piqued my interest with the NOS approach, so I’m going to try out a Wavelength Audio Cosine DAC with the NOS setup. The topology uses a passive I/V stage, Mangaquest transformer coupling, and a 6GM8 output valve. Should be interesting to see how it sounds.

So, who else has used NOS DAC’s, and what are the observations? Interested in folks take on them (likes, dislikes, strengths, shortfalls, etc).
