I auditioned the new B&W 704s yesterday, listening to CD players in the £1000-£1300 bracket through an Arcam 32 amp, and was staggeringly impressed with them as musical speakers. They were terrific all-rounders, handling the good old rock'n'roll of Neil Young and his Crazy Horse as well as the more subtle finesse of Steely Dan and Moby. I'm definitely planning to buy a pair but I have a quandary on how to complete my multi-channel speaker system. When it came to testing the B&W system via a DVD and surround sound receiver, the HMT7 centre speaker gave superb clarity to voices, and even gave Tom Hanks's vocal cords a rich and pleasant timbre. The 704s as fronts picked out every scrunch of footsteps in the gravel. However, I was less certain about the rears on offer, the DS7s. I'm sure they were doing a good job, but for £900 I'd expect a bit more than that. What do people think of the idea of using the 705 standmounters as rear speakers, which are the same price as the DS7s? I listen to a fair bit of music in 5.1, and my instinct tells me this is the way to go. But will I lose out when watching films? Is it sacrilege? There's a part of me too that thinks it might not be the best use of £900 to use them as rears - I'll have to buy a few more DVD-As and SACDs to play through my Pioneer 868 to justify it, if only there were more worth buying! I'm testing the 705s tomorrow and having another listen to the 704s. What are people's thoughts about whether it's preferable to use specialist rear speakers (inc dipoles, bipoles etc) or hi-fi speakers as rears?
