I'm looking to make use of my Rokit 7 G4 speakers in a living room setting. Sources would be AppleTV/TV, CD Player, Bluetooth. I think something like the DO100 Pro would do the trick, but they dont actually market it as such. Are there any gotcha's to using one this way, or other suggestions which might work better? I also looked at the Tpping E70 which specifically mentions Pre-amp function...but is twice the price.
