Thanks for your advice.
I've never owned a Yamaha receiver before, but did own a Pioneer VSX-A5i (I think that was it!) before the days of HDMI and I had a lot of respect for it. I liked the Cyrus type sound, I'm worried that the Yamaha might be a bit soft for my taste?
I wouldn't describe the sound from DSP-Z7 as soft, but it is warn and a bit dark compared to some of the competitors.
What I found most remarkable is the bass control. It simply outperformed all the other receivers I tested in this regard.
