I would like some feedback on the real differences I might get with an upgrade. I currently have the iGrado's and a LDM+. These are sourced by a 5G Ipod with all lossless compression and connected with ALO's new copper Ipod dock connector. So, the question is, for these headphones which are nice, but not really high end, will I hear an appreciable difference if I upgrade to the Hornet M? and would it be worth the additional $$ to get the PRII?
I realize these are both higher quality amps, I just don't know if the iGrados will let me hear the difference.

Thanks.
