Onkyo TX-NR414 5.1 Network AV receiver (HD-Audio, 3D Ready, RDS, USB 2.0, Apple iPhone / iPod, 130 W / channel) (Electronics)
Update 21.04.2013 So, after a night out drinking, reading a lot - but also calm approach - I have for a very simple upgrade path without TV and after successful firmware update found my optimum receiver :-) Everything is going exactly as I hoped it.
