I'm trying to build my first real home audio system.
Planning to start building with a Denon 1803 receiver plus a set of
fronts.
I'm thinking of using a pair of good bookshelf speakers as my fronts.
I'll add a sub and rear+center a couple of months down the line (don't
have enough money yet).

I've shortlisted the following speakers after doing some research on
UK sites.

1st pref: Monitor Audio Bronze B2, Acoustic Energy Evo1, Mission M50,
Mission M72i

2nd pref: B&W DM600 S3, WHarfedale Diamond 8.1

Could someone please give a comparison of the above speakers or these
brands in this price range (£150-200 per pair)?

I would not mind going for the more expensive Mission M51 if I were
convinced the the fronts would make a very significant enhancement to
the entire system - when it is ready. A major consideration for me is
the price/quality of rears/center/subs from the same brad - I'd prefer
to stick to the same make.

The Denon is 80W PC whereas nearly all the spekers are rated up to
100W. Is it preferable to have a higher rated amp drive the speakers
or a higher rated speakers driven by an amp?

In addition, how would you rate the MISSION CINEMA 71 PACKAGE. It
seems like a good deal.

Thanks
