It depends if you need an amp or not.
By the way I can't see any difference between running through and integrated amp, or active speakers. As most actives will have a pre-amp/power amp section. (Remember not to buy a set that use a DAC to convert music digitally to second speaker.
The difference is mostly that the active speakers have electronic crossovers which means that the individual amplifiers in them are connected direct to the drivers without any of the passive crossover components in the signal path. This can make a big improvement to the sound. For instance I have heard the identical passive and active versions of the ATC 40 Mk2 speakers (in other words everything is the same except that one is passive and the other is active) and the differences are so big that you would think it is a completely different speaker. It is even possible that the advantages of using TT2 direct to passive speakers is outweighed by taking a different Chord DAC direct to active speakers..
