Again though - I suspect the wildly varying differences are more personal preference and our own unique physical and mental idiosyncracies - rather than quality control issues at Grado. We can agree to disagree anyway.
I know we had very big differences in the way you and I heard/appreciated the SR line. Your preference for the 125i was at complete odds with mine. But that's what makes this hobby interesting - listening to other's POVs and comparing them with your own.
1. I'm with you on this one
2. Im with Biscuitz on my preference of the Sr125, well at least vs. the 225i (never heard the 325's).
