What does it take for me to fully transfer all my songs from my MK1 10g to my MK2g DIRECTLY.
There is an EmpegClone utility, included with the Emplode software, that's designed to do precisely that.
It uses USB, so it's not the fastest thing in the world. Expect it to run overnight or longer. If you use it, make sure that you're using version 1.03 of the software in all places (Mk1, Mk2, PC). The later betas are not stable for something this big.
I also noticed that MK2 didnt come with the grounding wire.
If you are referring to the floating-ground RCA amplifier adapters, you can remove them for the Mark2. They are only needed for the Mark1. This is
covered in the FAQ.
If you are talking about an actual ground connector for the main power to the sled, both products have a ground wire and of course need to be properly grounded.
