red boards,green boards,the difference is????exactly how old is the red board?? i now have tried to purchase a couple of different amps to complete my 7.1,funny thing is they all say ,"it's 2yrs old",but ends up being 3yrs or more..now my HT-3 is 2.5yrs old with red boards, u ask me anything about my eqipment and i will tell u the truth!!!!! i now know that u have to dig into the audio history of your product with the seller,because they act dumb!!!!!!! how can u buy $8-$10,000 amps and not know what u have??? i may not know it all,BUT i know what i want..so when someone acts dumb ,GRRRRRRRRRR,it's my money and i will protect my investment.
