Tre's answer is very much to the point, but I'll add the notion of why:
When vinyl reigned, cartridges required lots of additional gain (and equalization) in order to drive a power amplifier. Preamplifiers served that purpose along with providing input switching among other things. Today, many digital sources are capable of driving an amplifier directly. All that is needed is the ability to vary the output level and balance.
I used passive attenuators between my last CDP and power amp because it had not only extremely high output - 4V - but also very low output impedance so it was well suited for that purpose.
