Nice reviews. How about the Pioneer SE-MJ31? It just came out, I love them.
No such plans in the near future. Someone asked a similar question on the previous page but I'd be more likely go for an HDJ500 or MJ71 with my own money.
EDIT: BTW, I should be getting those Sportapro's soon and I'll stick them in a phone with some big round cups like the Kanen's and let you know how they sound.
I may try the same with the XO Vision but I'm really digging the way they sound right now in their original enclosure.
I have my doubts about putting Sporta drivers in a closed enclosure but good luck...
