giving advice is always easy.... but I think if you have with the SR80 and the SR325is two headphones you really like you should enjoy listening music with them. I have several Gradessandors (SR80, SR325i, HF1, PS500, MS-pro with distancers and G-cush) and I am listening to all of them. This is a luxary but xhat I realized ids that the choice of headphone is depending not only on the type of music I listen and the quality of the recording but also on my shape. I had it once that I was listening one night to a song with the PS500 and found it awsome and the next day I changed to the MS-Pro because the mid-bass hump of the PS500 was too much for me at this moment. So, my advice is if you want to keep things simple, stay with what you have and enjoy the music. I really think this is what hifi is about. Graphs are great. Despite theat they ignor the shape of our ear and sonic education our brain had. This if you have a system you like - enjoy it. Don't change it on something written here. Of course if you have a chance to listen to a RS1 with your music - do it. It is always good to question the establishment and see if it is still valid. So, I stop giving advice. Last word: With any of my gradessandros I would be a happy music listener.
