B& amp； W684 65438+100000, eci-3 amplifier 70W, not bad. Personally, I think the power is a little small, but personally, I think the effect of using the 6-series amplifier of Joan marantz should be good, and the power should be controlled within 150W. It's all just personal opinions. I hope it helps you. Don't pat the brick if it's outrageous.
