Looking at buying an amplifier, this will be my first. I am currently running a Pioneer Elite 49tx with Paradigm Studio 100's front, L&R, LCR450 Center, Studio ADP's surrounds and Paradigm Eclipse in the rear back. Also have a JBL subwoofer -- which I am not happy with and will be replacing but that is another post. I want to buy a 5 channel amp. I am interested in the following: Parasound 2205, Earthquake CineNova Grande, and the Carver Cinema Grand II. Please let me know your opinions.
