I'm quite content with the RS-1.
No, because then people would want to see them even cheaper, and so on. Because I've read (and posted ) statements that the GS-1000 shouldn't be $999 either. Assuming it wouldn't destroy their margins, I think all three of the "top" Grado 'phones should be within a few hundred of one another. Sort of like how the RS-2/PS-500/RS-1 are. I think the MASSIVE jump up to the GS-1000 and then the INSANELY MASSIVE jump to the PS-1000 is what throws people. They aren't just more money than the RS-1, they're more than twice more (and one of the most expensive headphones ever made)!
And even if we made them priced "realistic" there'd still be chart warriors who would disagree with Grado in general.
The 325 is the most revised Grado headphone afaik. I know of the following:
SR-325 in black plastic housing
SR-325i in golden aluminum
SR-325is in chrome/nickel
SR-325is in satin
And there's also an SR-300 and probably another one that I'm forgetting on top of that. I think Grado very much intends it to be their "sweet spot" headphone, but I also think they change it so frequently it's hard to accurately talk about. I should qualify that when I'm talking about SR-325, I'm talking about the goldies.
