I have NS690mk1 and they aren't getting much use in my listening room. I have a home theatre in a box (blue ray player with 5 X 3ohm slim tower speakers. I will buy a receiver and replace the blueray player and buy speakers to work with the 690s or if its not worth it ill buy a home theatre speaker set and receiver. Is the 690 worth considering in this role? PS: i understand i can add the 690 to the blueray as they are 8ohm and the current speakers 3ohm...but wont be a lot of power available for them? Is it even worth considering? Blueray/amp is Samsun D5550W no power spec avail other that: total power=1000w - but who know what that means.
