No, I don't have a list. I just want "good" sound which I define to be the things I talked about above.
You might have a good reason for not upgrading. I am saying "might" because I haven't listened to movies yet. I can tell you though the 160v4 is fantastic and you should not torture yourself with the 150 which I imagine is v2 or earlier.
Agreed that soundstage (depth, width, height) have a lot to do with placement. I am seeing improvements
with the v4 over the v2. These improvements, along with others, justify the upgrade for me.
