I prefer to use Audessey above an other system. Maybe Dirac would be nicer, but Arcam is a lot more expensive. I do like the design of the new Onkyo line. I would have had to buy at least the Onkyo TX-RZ1100 to get the same basic specs, 9.2 amplification. Where I live the Onkyo is 1999 euros, whereas the Marantz is 1799. I got a super deal on the Marantz, got it for a lot less. I also use a UD5007 from Marantz, so the SR7011 is a better visual match. My speaker layout is better suited to accommodate Auro 3D which I can get as a paid upgrade. That played a role. Both my previous Marantz SR7008 and Onkyo TX-NR809 had a HDMI board that failed. Both where repaired and still function. So that was not a issue. Both Onkyo and Marantz match very well with Klipsch, although just my opinion. It's just that the Marantz appeals to me more. Just a feeling. Hard to describe. Onkyo is slightly more neutral sounding. Although my current Marantz is also more neutral sounding as far as I can recall then the SR7400 I had a long time ago. Maybe my next amp will be a Onkyo in 2-3 years. Who knows:). I do not use my setup for music. Just movies and games. I have a different two channel vinyl audio setup in the living room.
