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.
bpcans, yes i'm so happy with the DF, my Asus Xonar ST (throw headphone jack, No Gain setting, ASIO) is not loud enough with my ATH-M50
but the DF is loud enough IMHO.
I wish if someone can download the sound test file and try it on his/her own DF to confirm my situation.
Because I'm a kind of guys who buy the things and use it for many years, so I want to be sure that all my gears are optimal, i'm just listening to lossless files, via headphone, so I never use any more features.
I have both the Dragonfly 1.2 and the E17, if I am using my MacBook Pro in my study, I tend to use the optical out into the E17 as a DAC that then goes into my Marantz Amp. However, if I am on the road then I use the Dragonfly straight into my HD600's. Obviously this gives me two signature sounds, but, I am more than happy to use the DF and the Sennheiser's at length when I am writing up reports and chilling after work stuck in a hotel room. I also like using the DF in my MacBook if I am catching up on downloads from iPlayer late at night sitting next to Mrs Rearwing.
