In that case the RS1i that I had must have had a problem too, but personally, I don't think so.
I think that it's a combination of facts that contributed to me not keeping the RS1i, I won't lie, I had read so much positive thigns about them, that my expectations were pretty high.
Also it's not like I was buying the RS1i, because I didn't like the headphones that I already own, I just wanted headphones that could give me a lttle more intimacy with some recordings, and even though they did gi me more intimacy, the lack of decay and ''air'' around the performers, made for a sound presentation that I just didn't care for. So keep in mind that this was the only thing that I didn't like about the RS1i, but it was a copromise, that I wasn't prepare to live with.
In my opinion,, the first gen GS1000 have THE biggest soundstage of any Grados with decay and ''air'' to spare, but, they also have THE most recessed midrange of any Grados.
I find it funny that when someone says that they don't like the GS or PS1000, we rarely see people saying that they're must be something wrong with them. It's ok though, I learned a long time ago, that the important thing is that, I, like them.
