Please check an audio stream for me: Left channel is about 5-6 dB higher than right?

Hello,

First time post here -- I hope this is the right place to post this...

Would someone who has a good audio ear please take a listen to this stream _mms://nick9.surfernetwork.com/HomeGrownRadio
and see if you hear what I hear, which is that the left channel is about 5-6 dB higher than the right channel, and then report back your results. The station manager says the signal is leaving his encoding computer completely balanced. I even sent him a short sample WAV file which I captured and he said it sounded fine to him...you can find that sample here _http://www.panix.com/~am_dew/HGRNJ_sample.wav if you want to take a listen.

I have checked this same stream on several computers and they all have the same channel imbalance, so I know this is not unique to my computer.

Thanks!
