ASR has some good discussions and links that explain the differences in DAC architecture. First the analog has to be converted to digital nowadays this is done almost exclusively with Delta Sigma ADCs. The goal is get the signal as true as possible this is where your numbers and measurements come in. Next comes the DAC to reverse the process. All of the differing architecture’s will accomplish this which does it with the least distortion and noise is the point of the DAC. It doesn’t matter which architecture of DAC you use as long as it can do the job accurately. Delta Sigma DAC’s are easier to implement so they are usually cheaper though not always but since you aren’t looking to buy a 5 figure DAC we’ll stick with that premise. R2R DAC’s can measure very well but they usually cost more see the above link to the Mojo DAC that runs about $5500. You can get a DS DAC that will measure just as well for about $250-$1000. The Topping D90 is a good example as well as the Sabaj. Don’t worry to much about how the DAC works just know they take a digital signal and turn into analog. The differences in the sound as was pointed out by the comparison of the Wolfson and AKM DAC’s has more to do with the type of filtering they employ. My guess is the Wolfson is using a Slow roll off hi pass filter or bypassing the internal and Cambridge used an outboard filter, AKM might have used the Sharp roll off giving different sound characteristics, the Wolfson emulating a LP sound that a lot of people find more pleasing to listen too. The best thing is listen for yourself and find what you like whether it measures good doesn’t matter if you like it.
Comparison of latest DAC chips
I own a Bluesound Node 2i which greatly improved sound after I added the Cat 6 cable. I do not own a separate DAC but am told it would be the next step improvement. I have done enough reading that it appears the two latest chips are the Sabre or ESS
ES9038PRO
and the AK4499. The brands I have looked at are Sabaj d5($469) and a Topping D90($699). I saw a great review on Audiocircle of the Sabaj D5 which is now a year old. The Topping D90 is newer and I hear the build quality of the Topping as well as customer service are both better. Other brands cost more and most don't use these new chips.
Is there a difference in how these chips sound? I would appreciate any comments.
