Bits is bits? They aren't when they come out the other end, but rips are generally bit perfect (dBpoweramp checks the rip against others to make sure).

Unfortunately there's a scientist in me somewhere so no- there can't be any difference. Aren't the Naim boys famous for smoking weed?

You could start with a squeezebox/computer server and DSPs and take it from there (can't see what kit you have).
