A lot of it just comes down to personal preference, and I really don't know if that preference is worth an extra $300 out of my pocket (I was dead set on grabbing a pair before the meet). I did hear it out of two completely different sources though, so I'm relatively certain it's not just my mind playing tricks on me.
Shame about the AKG K167s. Not sure I mentioned it, but I liked what I heard from them. Seemed a bit light in the mids, but not in an unpleasant (to my ears) way.
As a follow-up, my actions to EQ the frequencies a bit in the 2kHZ to 6kHZ range were successful. One evening, I had located an older ADC EQ off of Craislist, in the event I couldn't get the software EQ running in the Logitech Media Server for my Squeezebox. However, I did get the software EQ version running and adjusted as a plug-in for the Squeezebox. I tested the older, analog EQ, too. Both did a wonderful job at correcting some of the sound limitations, or weaknesses in the HE-400s when it comes to female voices. To me, the HE-400s are a different sounding headphone now in this regard. I had not listened to many female vocals on the 400s for the past few months, so I had been a bit out of touch with the perception of the sound. But, I'm glad this was visited, based on some feedback in the forum I had been reading, and some comments on their sound signature from the meet.
I believe, all too often, a headphone can be discounted because someone will find that the sound doesn't appeal to them. But, if the option for doing some slight adjustments in their audio chain via EQ, then I would encourage this activity to be done first before selling off something that doesn't do an area of sound well. All too often, I've ended up selling off an item because of a sound signature that I wanted to change. Usually, this meant jumping from one issue, only to discover that the next item had something holding it back, too. So, instead of jumping products, it might be best to work to see if the small nag that's bothering one can be resolved.
Here's a graph of my EQ settings. I may go back and bump some of the frequencies back towards the "flat" level that I had dropped down as I was working on the female "S" sounds. I bit more fine-tuning is easily possible.

Ironically enough, I had purchased the K167 from Amazon. I had used next day / Saturday delivery upon purchase so I could have them the weekend before the meet. Amazon provided a complete refund, to exclude only about $6.20 to get the headphones returned to the vendor. This is a really great policy of Amazon's that I wasn't aware of. Yet, I hope it doesn't get abused as I'd like the policy to still be in effect if I were to encounter any future issues with purchases that they've fulfilled.
