I now have 3 opps'make that 4 per amps. A CAT3 a First Sound and the Placette passive--The 4th is a Macormack rdl.---The Placette is by far the cheapest---and cheapest looking too. If you can find a way to get the Placette next to the amps and use a 1mt. cable to the amp---you won't believe what this cheap looking thing can do.--We know where the money went;not on the looks,--but on the sound. Be amazed;try one. You can sell it for what you paid in a minute;if it don't do magic for ya.
