Why can't someone splice USB? You CAN splice USB just as well as you can RCA or some other more pertinent connection.
MPC will never, and should never, give a 10 based on someone wanting to modify an 8th grade electronics class cord....and make it easy. It's USB you soldering iron holding freak!
The speakers they've given 10's to are great. They've been engineered very well and have the perfect amount of cord. If you want to add more, than you're the judge and are taking 2.0's out of their element. When you want to move the placement out of perfection, then...it's your call, not MPC's. And you've missed a couple years. They've done notjhing but studios.
Here, If I based my opinion on re-wiring...it's a mess bro.
