I am an amateur singer and music enthusiast. I have a vintage Carver Model C-4000 High fidelity holographic image Control Console, and this processor is fantastic. It was the predecessor to surround sound, way before surround sound became viable. I also have a Carver M-1.5t Magnetic Field Amplifier, and it is capable of 600 watts per channel continuous. All of Bob Carvers Audio Components were way ahead of their time. i also have a pair of OHM Acoustic Walsh Series speakers that are also ahead of their time when they were new.
