Dear lewm, the MC7500 has a tendency to sound a little edgy or bright in the wrong set up. I think this has mostly to do with that Ortoline stylus profile. So spot on azimuth and SRA are crucial, but I assume you have that covered.
It took some time to find it, but the LH 7500 headshell made a very positive contribution and so did the LW-1000S leadwires. You would think 7N copper would be the best match to the 8N copper coils (8N copper lead wires are not offered by Ortofon or anyone else I think), but these silver wires contribute to a neutral balance comparable to MC2000.
It sounds very good in FR64S (all my cartridges do, even the high compliance MC2000), but even better in Audiocraft AC-4400. And perhaps contrary to what one might expect, it likes the phono amp (at 500 ohm loading) better than the Ortofon T3000, which is basically the same as the dedicated T7500. Hope that helps.
