I use PSB speakers - Century Series (1000i, 200ci, 600i), and have had no problems. The 1000i's are 4 ohm, and the 1070 has no problem driving them - in fact they sound better with the 1070 than with my old reciever. I think that you will be very happy with how your PSB speakers will sound with the 1070 (set at 4 ohm).
