Interesting! As I mentioned before, I would not call the NOS DAC's sound analog per se, but musical, and thoroughly enjoyable. I think analog is just a easy description. They aren't perfect by any means. What Dac is?!?! But their faults are more of omission. Along with common sense isolation, I think if you use good, quiet and 'quick' (fast rise times etc) plentiful amplification, and sensitive sealed bass speakers, NOS can really shine. The "soft" or "rolled off" highs won't be apparent, and the bass will be full and tight. If you have tuned your system to DS DAC's or similar sounding DAC's, I don't think you can totally appreciate the sound. I think audio went a weird route with inefficient flat sounding speakers for years to cut the harsh edge of digital. Then turned around with overly bright speakers with little bass. Called them HD ready. Huge floor standers that STILL required subs?!? NOS DAC's IMHO are a good way of keeping you grounded, and enjoying music again, instead of listening to your equipment. Who really cares about the specs, and technical aspects? As long as your enjoying you music, not your equipment, that's all that matters. Equipment, specs etc are just a means to a end. For this cat anyhow.
