Hi Marco,

That's a good test!  I'm not hearing much difference between the two  
sound samples.

So the preamp of the iRig doesn't really do anything, compared to  
just adding a phantom power source, for small flash card recorders.

Another question though, is there a difference in sound quality for  
iRig when using LINE IN vs MIC IN?

cheers,

Vicki
