I confirm dweaver's comment; the cups on the NADs are smaller than the P7s. The P7s fully "circumnavigate" my ears (although my attached lobes get pressed a little). Feeling a bit better about the NAD fit today. If I nudge my ears up, sort of into the fold between the pad and the driver, it gives my lobes a break and also kinda flattens out my ear (effectively spreading the contact with the thin cushion over the driver grill). So I'm not getting so much localized pressure on the part of my ear that sticks out the most.
I'm still concerned (and perplexed) by the bass. One of the tracks I use to test bass is "Fire" by the JHE. Yes, it's a nearly fifty year old recording but the heavy bass riff that opens the song is helpful to me in determining the extension and effectiveness of the bass. I was shocked to hear how the NADs handled this. It sounded "out of control" and overblown. The P7s handled this with less bloat and more detail. The "shock" came from having read all the comments about the P7s bloated bass and the NADs supposed neutrality. Again, I'll see if the bass settles down after some more burn. I do agree that the treble is more neutral than the P7s and I like it better. Even though the P7s have improved with time, they still have occasional harshness in the treble.
So this is becoming a real horse race, as to which one I prefer. Right now they both have pros and cons.
it's either keep one or send 'em both back!
...or, heaven forbid, keep 'em both!?
