First of all, sorry for my english. I want to buy an AV receiver for my Home Cinema System and I´m not sure what is the best of: Pioneer VSX-AX5AI-S, Yamaha RX-V2500 or ONKYO TX-SR702E. I Think all are very similar, except for the power (since 100W to 170W per channel), connections (Pionner have iLINK and USB connections) and prices (Pioneer model in Spain cost is 300 Eur more than Yamaha an Onkyo models. Pioneer 1.394 Eur, Yamaha 1.007 Eur and Onkyo 922 Eur). I have a KEF 2005 surround set in 7.1 configuration. Can somebody help me?
