I am currently using a pair of Chimera Labs IC's. They are great and musical, but recently I have had some concerns over the fact that they are unshielded. I have noticed an element of hum and hiss/noise on my amp when playing headphones that is present, it is not intrusive when music plays as the noise and hum is well below the noise floor of the recording, but its there, especially when I turn the volume up. However, when I plug in with no source attached, the amp is virtually dead silent, much quieter than with the source plugged in with the IC's. I know the noise could be coming from my source (Meridian G08), but I believe it may be more RFI and electromagnetic interference in general.What are some audio cues that I should be listening for, that could help me ascertain my current situation with shielded vs. unshielded ic's?

- What you hear in the absence of signal is audio band EMI or noise. - Al Sekela 15:27:35 03/24/07 (8)
