I am using kef eggs(1005) and kube1 sub + eltax sw20 sub. I reckon it can perform better with some decent speakers. got it from Richersounds and guess what they always push u to buy Onkyo. I had a demo between 607 onk and yam in a shop in Maidenhead. I liked the Yamaha as it wasn't distorting at high volumes. I am happy with Yam
