That's interesting. This version would be more in line with subjective impressions at the Austin meet where folks said the MD's were all mids (Maxvla, twiosp or MorbidToaster, correct me if I'm wrong here).
I agree with ultrabike though. At the LA meet the Mad Dogs were boomier (more mid-bass) than the Paradox. I don't think these were the Alpha pads though, but rather the Dog Pads (??). It's really hard to keep track of all of the changes. I'm sure MrSpeakers is doing right by his customers by offering upgrades as he makes them, but it must be kinda frustrating to have to keep an eye out for any revisions as they come. It was part of the problem when I was modding the T50RP's -- they were never "finished" and I'd always feel the need to tinker with them to get them better. You'd think if someone offered a product commercially, that it'd be "finished".
I have noticed though that when someone has one that measures badly, or doesn't like them, Dan's explanation is that the headphones were from a bad batch that somehow made it into the wild, or from a previous revision that has since been changed. That explanation is convenient the first time, but after a while starts elicit skepticism.
