I am currently using a Behringer DCX for my ScreenArray speakers in my home theater, and it does a very poor job in my opinion. Much hiss in my HF sections and not very refined sounding.

I have found a DBX DriveRack 4800 under half the price of the MSRP and in perfect condition, so I am very tempted to buy it. I have read somewhere on this forum though, that DBX products are not very good and what goes in is NOT what comes out.. Is this true for the 4800 as well, or is it only for the cheaper models?

Would the BSS London units be a better choice? (I know these are used in the Synthesis systems).
