Martin - would be interested to hear how well-mastered music plays between the 7510 and 20 when you're properly run-in. Anything from the BBC stable tends to be very well mastered (most tracks from the Live Lounge discs for example).

Out of interest, how long should the 7520 take to run-in? I'm itching to compare against the CA DM (and maybe a Supernait if I can rope a friend in), but haven't got much time on my hands at the minute.
