800 watts of power!

Hello, my brother’s end socket has given up the mind. Now I wanted to know if this was even good, because I want to get the same. These are the values: MaxPower: 4 x 200 watts or 2 x 400 watts (bridging) or 2 x 200 watts and 1 x 400 watts (bridging) RMSPower: 4 x 100 watts or 2 x 200 watts (bridging) at 0.5% distortion factor (4Ohm) New price 249 € Are you paying to get this end stage again? And is the RMS power sufficient? (whatever that means , the mei sten talk about the RMS performance) Don’t know me that way! Thanks already for the answers. MfG
