After listening to the Hugo with teh SD and HD micro inputs for a short brief moment, I've noticed that the ASIO driver installed for the HD on Foobar2000 has "hiss" noises and the SD does not. The "hiss" noises is very noticeable when I am multi-tasking on my Laptop (I believe this has something to do with the performance of my laptop, since it's only using an i3-processor), especially browsing the internet. This does not happen when I use the SD input however.
Fortunately, most of my mp3/flac files only go up to 44khz but I can't wonder if there is something I can do to get rid of the "hiss" noises when using the HD micro input.
My headphone collections are:
AKG K545
AKG K812 Pro
Sennheiser HD800
and each of these do experience "hiss" noises from the HD micro input.
Any actions I can take to resolve the matter?
