Do you have noise in your system using the 2.8V outputs?
Phoenix Gold is also a good brand. I have never used Planet Audio so I cannot comment on the quality of it.
Where are you located? Canada?
I have an Audiocontrol Matrix 6 channel from my old setup just laying around. The thing is Mint Condition besides the marks from the mounting screws.
I'll send you a pic of it if you are interested. I'll let it go for a good price as soon as I figure out how much it costs to ship to Canada.
I also have a Audiocontrol Master Volume Control 6 channel I also need to get rid of if anyone is interested.
