After listenig I have decided to buy B&W CM7 speakers, I actually heard them paired with Arcam - A18 amp and CD17 player. It sounds great, they recommended me this combination rather than Rotel... I'm just little bit worried about amp - is 50w enough for this speakers? Im beginner, I don't want to go wrong. Is this combination ok, or would you recommend me something better at this price line? Thanks
