The more I listen to the 325is the more I think they were made with me in mind. I have other good cans (SR60s, Ety4P/S, 501s, 701s, 2200s, Stax LPs, etc, etc) but with the 325is I feel I've finally come home. I'm old and and my HF hearing is taking a nose dive so what's bright for you may be just right for me. I find the synergy between my Pany SA-X55, an all digital all the time receiver (which I use only with phones) and the 325i is what I've been searching for so why do I persist in asking about R2s? Simply because if the RS2s are even brighter, clearer, more detailed and transparent than the 325is then I want them. However, from what I've read the RS2s are more true to the music. This is what I call replicating the classical concert hall experience. In this domain instruments are not heard as separate and distinct but meld into a wall of homogenized sound. This is sometimes called listening from the 30th row and Sennheisers do this so well they're the phones most often recommended for classical music. While this purist approach may be the way classical music should be heard it's not the only way it can be heard. You can hear these different approaches in the various ways classical music is miked and recorded. Classical audiophile labels like Hyperion, Chandos, Telarc, Reference Recordings, Dorian, Bis, Stereophile Recordings and Delos (to name but a few) produce recordings that let us hear singers, choirs and instruments as individual voices which are then combined by our brains into a whole. This unique ability to capture clarity, detail and transparency is what makes Grados so special, so surreal and so much fun. If the SR2s offer even more of this kind of experience then I want them and explains why I'm so curious about them.
