Benn, we have just bought the Onkyo SR674SE Av Amp/Receiver. It has just been superseded by the 605/705 models, so is excellent value for money if you can still get one. Was a £500 amp when they came out, we paid £299 a few weeks ago.
Has Zone-2 function for running a second pair of speakers in another room from an independant source amongst other great features.
