Static?

post #1 of 3
Thread Starter 

First post here.  Please be kind for any oversight on my part.  :)

 

I can hear static.  It is driving me nuts.  Not being very experienced with configuring for a flawless audio experience, I started researching and came across this site.  I am now using Shure SE425 Noise Isolating earphones.  Listening to Pink Floyd's Money off of Dark Side of the Moon.  The Shure's are connected to a Pioneer VSX-521 which is receiving input from my computer via Fiber off of my SoundBlaster audio card. 

 

When there is a "break" in audio, especially at the start of the song, I can hear static.  I have not heard this in the past but then again, I have been using low quality earphones.  Is the static the earphones are creating?  Perhaps a low quality version of the song?  Something that may have been there all along but now with better earphones I am actually hearing it?

 

Any response or guidance would be very much appreciated.  Thanks in advance.

The most likely cause is the DAC in the sound card, but it may be the amp's high output impedance.

 

If you listen to audio straight from your soundcard and bypass the Pioneer what do you hear using the same track and test conditions?

Agreed. Some AVRs may not be suitable for low impedance headphones like the SE425 and may have trouble driving them. Whether that would cause static like you describe, I do not know.

However, I have experienced static over bad optical connections. So perhaps the optical output on the sound card is causing the problem. Does your graphics card on your computer have HDMI out? You could try that instead.
