I have been very happy with my 990 and 7125 so far! But, I would like:

1) I use the Zone 2 feature of the 990 to run speakers throughout my house. One minor irritation is when you push any buttons on the Zone 2 remote, the 990 display does not come on to let you verify anything such as Zone 2 ON/OFF status, or volume level for Zone 2. But, if I first press a button on the main remote, to activate the 990 display, and then press the volume button on the Zone 2 remote, the 990 will display the Zone 2 status, volume level, etc. I suspect this could be fixed with a firmware upgrade.
2) The ability to at least have the unit automatically measure and report/display the amplitude response across across the audio band.
