Short version: I have a chance to get a deal on some Grados. Within the Prestige line, which one should I get to compliment my Modhouse Argons? The Argon has a warm/dark sound with epic bass and the most immense soundstage you can get from a closed headphone. I want an open, more detailed, brighter headphone to compliment it. Is the SR325e worth the higher price, or is there a model a little further down the ladder I would be just as happy with? Longer version of the story, if it interests you: I recently got a set of Modhouse Argons made for me and I could not be happier with them. They were the missing piece in my headphone 'collection'. For every use case scenario I have a headphone I really like, some I love. I literally had no new headphones on my radar for the first time in a long time. Then, as the old saying goes, up jumped the devil. It turns out a customer of mine happens to own a company that sells audiophile products. I can get a great deal on some Grados, so the question is, if I decide to get one, which is the right Grado in the Prestige series for me? I mentioned my Argons because they do so many things great, they are a closed, warm, dark, beautiful cave of a headphone, but I also love an open headphone that has detail and brightness.... Which of the Prestige series is the best representation of the Grado sound? Or should the question be, which of that line would complement the Argon best? or....maybe I am asking, is the higher price of the SR325e worth it over the less expensive headphones? If I add a Grado, it has to be better than the open headphones I already have (Modded SHP9500s) I want it to be on the same level as the Argon.
