I am looking to upgrade the speakers on my Onkyo CR-435 as I have the bog standard one's that come with the unit. I have a budget of around £200 with cable what do you oracles think. I was in Superfi and Audio-t and they recommended these option to me the Monitor Audio BX1, The Roth oli4 and the Wharfedale 10.1. Any Help would grateful. jk1988
