The only Grados I ever owned is the sr225i, I have them right now.
as I continue to listen to them i do tend to find them to be a bit on the bright side, I was wondering if this is a characteristic of the higher Prestige series. As I look at the charts on frequency response, it seems to get brighter and brighter as you go up on the line for the prestige series
As I look at all the other series, they take on a more even V response (As in the peak in the low and the peak in the highs tend to match up in dBr), does this hold true for the sound?
I certainly think this is the case.
If you didn't know about it, you can wrap electrical tape around the outside cushions of you 225i, which tends to tame the highs and bring up the bass a bit. One of the best mods I've ever done!
