On the technical features I need not go into that Frankie has already done in great detail in its recession. Just a small note to the features shown here at Amazon: The 414 has NO Simfy client on board and according to Onkyo Support This is also not planned. On the page Onkyo simfy is mentioned figuratively only from the 515. I suspect Amazon is undermined here an error. The Simfy logo in connection with the 414er Receiver is unfortunately misleading. I am very satisfied with the device. It is tonally absolute peak, surpassing my previous receiver (Pioneer VSX 920) a lot. I had initially made me a bit worried that the 414 will be due to the lack of Einmessmikros set hard. But the worry was totally unnecessary. Where the VSX has 920 felt 100 settings, the Onkyo TX-NR414 offers all important settings at a glance in a simply structured menu. Setting up was easy and was done in a few minutes. Class equipment, great value and excellent sound!
