HT pass through or 2 sets cables?

I have a chord integrated amp for 2 channel and an arcam avr300 for video processing and surround sound. I want to keep the chord for two channel to power my maggie 1.6's, which are part of a theatre system. Would it be better to use the chord and pass the signal to the arcam and have the arcam control the whole system for theatre or just get 2 sets of speaker cables?
