I've just made a thread in the Amp/Receiver section asking for advice comparing three amps and apparently I've quite a similar dilemma with speakers. The Q-Acoustics 1010i 5.1 system is going for £399, the Wharfedale Diamond 9 HCP 5.1 system is going for £340 and the Mission 5.0 set is going for £370. The Mission comes with M33i floorstanders, two bookshelfs and a centre speaker (with no sub). Take into account that I'll need two pairs of stands with the former two and one pair with the latter. What I'd really like to know, is whether a sub is actually essential in the case of purchasing a system with floorstanding speakers.. would they produce enough bass regardless? Unfortunately buying a separate, quality sub along with the Mission is out of the question at the moment as I've already stretched the budget, but I'd always be able to upgrade in the future if it's needed. What would give me the most bang for my buck right now?
