whether its burn in, or psycho acoustical , (i think some of both) the sound i perceive initially , then over the long term, is often very different.
'm looking forward to your thoughts on the rs1i, you should have a good handle on how you like them by the time i get mine!
Yes I do agree, whether it be one or the other, over time they do sound different. I intend to spend a few hours with them every night with different souces/amp/dacs and listen to hear if I think the price difference is worth it. I can immediately hear they clearly have that Grado sound signature that I love, for the half hour that I listened to them. I'll get back to listening later, in the meantime they are hanging upside down from a hanger so the cord can straighten out and relax from being packaged.
And also the (L) cushions feel much softer than when I purchased them for my 80's, or the ones that came with the 325's, which had to be worn for awhile before they softened up, even after washing them (don't know why).
