When playing actual music, it seems to be correlated with the bass(?) which gives it an extra sense of musicality without removing detail. The distortion in the 16-bit dithered output, to me, sounds really nice actually. However, it did not produce distortion when using the RME Babyface Pro as a DAC. The dithered 16-bit output in foobar produces distortion on both the Schiit and AudioEngine DAC. 2 means I fed the recorded output back into that DAC, 3 means I did it one more time. Loop indicates how many times I rendered the output with the DAC being tested.
Our hearing is more relative than absolute, and I believe as long as you are using headphones powered by an external device, you'll hear an fairly accurate portrayal of the sound differences. I knew this would be an issue, but I extensively listened to the files to make sure I was satisfied with the quality. Some people will be concerned that in addition to the DAC being tested, there's also an AD converter used and the listener will be using their own DAC. Loop2 and 3 are going to be way too distorted from the repeated generation of harmonic distortion.įrequency Response Both were effectively flat from 20 Hz - 20 KHz, but the Gungnir had a rather stable phase across most of the audible spectrum, while the AudioEngine experienced a gradual 80 degree shift from the lowest to highest frequencies. Ok, so maybe my DAC is defective, or I broke it somehow in the months that I've had it? But, you can still get a general idea of how it sounds compared to AudioEngine in the file below, as long as you stick to listening to loop1. Harmonic components were at -90 dB or less. However, I just tested my Pass Labs XP-10 pre-amp, and the harmonic distortion was very low. They also tend to measure in the case of Ayre and Primaluna, not exceptionally well for THD. My experience with zero or minimal feedback gear from Ayre, Pass Labs, and Primaluna suggest I experience a much higher noise floor in my listening room than lab measurements from publications. Schiit Gungnir Multi-bit, WASAPI 16-bit output: Image. 24-bit and 32-bit outputs were effectively the same. Spectral Analysis I used an undithered 1 KHz, 0 dbFS, 44.1 KHz sine wave output from an AudioEngine D1 to the 470 kOhm line inputs of an RME Babyface Pro, converted back to 44.1 KHz audio.įoobar2000, WASAPI, dithered 16-bit output: Image.įoobar2000, WASAPI, 16-bit output: Image. I've decided to summarize everything in this subreddit, along with some extra measurements. Some of you may have seen this already, but I feel this subreddit gets a lot more activity, and is far more interested in both seeing and hearing the differences between two DACs.
