I have a Marantz SR5300 receiver and I have a Xitel Digital Pro Hi Fi Link connected between it (via a digital coaxial input) and my PC's USB port. I've had it set up for about a month and it's great (sound quality and all) and I usually use it to play MP3 files via WinAMP. But this afternoon, I had set up a MP3 playlist for the computer to play as I was doing household chores. I went down to do some laundry and I came back and I heard some awful distorted sound coming out of the speakers. It turns out that the software program (WinAMP) had been trying to play a corrupt MP3 file and all sorts of distorted sounds were coming out of the speakers (connected to the Marantz system) . Fortunately the volume level wasn't high (it was at about
-25 dB or so) so I don't think that the speakers would have gotten damaged. But my question is that, as this sound file may have been playing for ~10 minutes (ie. constantly playing distorted clicks and beeps for this time period), is it possible for this playback to have damaged either the receiver (either the amplifier or the internal
24-bit/96 kHz DAC) or my USB Xitel Sound adapter (although I think it's unlikely for it to have damaged the sound adapter since all it does is relay the digital input signal to the Marantz receiver)??? The reason I'm asking is because now, if I put my ear next to the speaker, I can hear a little hum (even in digital audio mode), even when ther'es no sound playing, and I'm not sure if I had this phenomenon before with this sytem.Any help or suggestions would be greatly appreciated.
