Get the 805S. It's a better speaker overall compared to the Monitor Audio. I've heard the MA silver series few years ago and those speakers have thin midrange and lacked body, hence the perceived brightness. Answers to your questions:-
1) It is sufficient unless you are looking to crank up the volume to serious head-banging levels
2) With the Creek there may be listening fatigue. In the long run you would be better off with the B&Ws.
