Gobble, you mean emission due to elec mag interference? Not sure if i could ever detect any such leakage in my setup.
I am leaning more towards 6003 due to its possibly better design and being somewhat future proof, with its usb and it'll suit my laziness.can squeeze a few cds on a usb forgetting about changing cds for a while. Even if the lens fails, i can use the usb. At least that is what my understanding is. But not sure about the quality through usb though and if it can access the dac in case of lens failure.
