The problem of mating a source to an amp can be good or bad, depending on the components.
Many times a direct feed, or just through a passive attenuator, leaves the sound too lean/thin.
A LOT of folks really ned the preamp to alow the music to have the proper tonal balance. All has to do with impedence and loads...
If your stuff works then you are lucky. If it doesn't, then you either have to search for a compatible source/amp combo, or buy a preamp.
