I am totally stumpted. I want alot of power in a power amp, and low distortion with high damping factors, yet the poweramps Im looking at have banana plugs and no Speakons or 1/4s. i.e. Crest CA12 and Crown K2. Would banana plugs affect my sound or power transfer? Are Speakons or 1/4s better or worse? Help! I've heard reviews that the QSC PLX poweramps have switch powering or something? I've heard that because they don't have toroid construction, that they're low end fails and doesn't have the same consistency or sound as a toroid-transformer poweramp. What do you think? The poweramp would eventually power 2 Eden D-410XLTs, so keep that in mind. Each Eden takes 700W RMS, so a total of 1400W RMS. Does anyone know if the Eden 410XLTs have banana plug receptors or only 1/4s??? Thanks, and please help me out. I'm a confused little boy.
