I'd go with the AD-700s. I now own the AD-700s and several years ago owned a pair of Grado SR60s. I primarily use the AD-700 for orchestral and chamber music. I have Dallas Symphony season tickets, and the sound I get from the AD-700 is remarkably similar to the live sound I hear. I would very much recommend them for orchestral listening and opera shouldn't be that different. The Grados sounded good for a while, but for a longer work, they got uncomfortable and the Grado 'sizzle' got a bit overbearing. I kinda dread what the Grado sound might do to certain soprano voices. But the AD-700 do need some EQ for more bass heavy rock, etc. I'm not sure what the Alessandro 'treatment' might do to the sound. If it takes away a bit of 'sizzle', they might be very good for opera.
