Whay do the Skyline JO and Daryl Jones cost more than the 55-01/55-02?

It would seem to me that the 55-01 and 55-02 have a build quality comparable to the Skyline Joe Osborn and Daryl Jones models but they also have active electronics. Why are they less expensive than the passive Osborn and Jones models?

 

Dude, i was going by the actual prices that I have seen these items selling for. So far, most dealers are selling the Daryl Jones for more than they are selling the 55-02 standard (not the Deluxe). And both the Daryl Jones 5 and JO5 cost more than the 55-01 by several hundred dollars in actual price and suggested retail.

 

So the Bartolinis on the 55-01 are Korean made? I know one can order the 55-01 with a different preamp and it will cost about $400 more or so. I don't care as long as it sounds good, I'm just curious. The JO and Daryl Jones cost more than the 55-01 because they have US pickups. Thanks for the info, Dude.
