Hi I already post a reply in Dragonfly thread but im afraid it wont be noticed,,
I just bought the dragonfly 1.2
I don't have much of experince about DAC/AMP.
I'm facing something strange, yet it can be noraml, so I hope anyone can verify it.
when i'm playing some sound test files I noticed some sort of noise at the max volume, one of the most obvious frequency is the 16000hz (16Khz) file https://www.dropbox.com/s/pwgkfpsniuhcbu2/16000hz.wav
I'm using windows 7 64-bit and playing throw foobar2000 using WASAPI event.
windows volume is set to max so as foobar2000.
the noise is so obvious between 0dB and -3dB, and a little bit of noise between -3dB and -4dB.
I have only one headphone ATH-M50 (impedance 38ohm).
please download the test file from here https://www.dropbox.com/s/pwgkfpsniuhcbu2/16000hz.wav
Is that normal or I got a bad (dysfunctional) Dragonfly 1.2?
I bough it from Crutchfield (Audioquest authorized dealer)
the dragonfly is connected to USB3.0 which is capable of delivering 900mA.
I tried it on my PC and my laptop with the same result.
Another thing, is it advisable to set WASAPI (Hardware buffer event mode) to 0, or it doesn't matter https://www.dropbox.com/s/hob9ntqvyq2u9ur/foobar2000%20setting.jpg
I already own Asus Xonar ST, and I think the Dragonfly 1.2 is better than it, later I will post an update.
