Dan Clark

I do, I do.
I was thinking he could have split personality.
A measuring side (Mad Dog), and a consumerist Sir (or Mistur) side with the Alpha decisions dog.

I understand that Mr. Speakers advertises and creates more headphone's than the other T50RP mods, possibly combined; but if baffle's me that they are preferred over headphone's, like the ZMF or LFF.

It was initially exciting that Dr. Clark and Mr. Speakers were using 3D printed cups. I really enjoy the individual parts he is using in his headphones: the connectors, the cups (mentioned), the thick leather headband, the doggie treats, etc... Yet, I don't think it goes together very well. They are just okay with what I use, and comparatively to other T50RP mods I have tried.

I think they are "preferred" in the sense that a lot more people have had the opportunity to hear them. Over the past 2-3 years I have now been to two Head-Fi meets and three audio shows.  Dan has been present at all of them with various iterations of his cans. (I happen to like them FWIW, but do not own any.)  I have never heard any of LFF's cans although I would very much like to. A few Smeggy cans have showed up at the meets that I attended, but no Paradox or other Luis can. So, it is hard to say whether people generally prefer Mr. Speakers headphones to others, or are just familiar with them and not the other alternatives. The other thing Dan has going for him is that he has a running production, so, some occasional delays notwithstanding, cans are more or less ready to ship when ordered.  Paradox and other LFF cans, as I understand it, are generally made to order. A lot of people can be impatient.  I think this helps explain the popularity of Mr. Speakers as compared to some other T50RP mods out there, in addition to the fact (IMO) that they are pretty good for their price.
