Thanks

I heard the Q Acoustics were very good speakers
They are just in the same way that an Denon 1912 is a very good amp, as is an Onkyo HT-S3409 home cinema kit. Each in the context of its peers is very good, but I wouldn't assume that a 5-star rating of a £300 home cinema kit means that it would beat anything else regardless of price. Similarly a 5-star rating for the Q Acoustics speakers doesn't mean they beat 5.1 packages at £1000+
The thing is there's a bit of a performance and price gap between speakers at the level of the Q Acoustics and the next meaningful step up. You're either going to end up buying something similar, or spending a whole lot more for the next step up in performance. Do you have £2000+ to spend on an amp and speaker kit?
The Pioneer is a good amp, as are most other brands at the £1000+ mark, and obviously there's a deal going round on the QA 2000 kit, but just because a retailer is trying to cash in on that doesn't mean that it's necessarily a good or appropriate match.
My view is that amps date quickly but speakers don't. Sinking all your money in to a flashy amp that's OTT for the speakers is shortsighted. Ultimately you'll have to replace both the amp and the speaker kit to get the next hike in performance. Buying better speakers now that will work happily with a lesser amp but also see you through a couple of generations of newer amp in the future is, IMO, a better use of money.
If it was me I'd go with the Monitor Audio BX AV2 package - £1000 for the speakers and then add an Onkyo 609 or Denon 1912 or similar amp.
The BX AV package will live quite happily with AV amps in the £500-£600 price bracket, but it will still deliver the goods with amps at the £1500 mark. For music the BX 2 front speakers are accomplished for music on their own right; that's always a good thing and surprisingly difficult to find in AV package speakers. The other thing is the rear speakers. They are proper dipole/bipole rear effects speakers as you would find in serious home cinema kits at £3000+. Diffuse rear surround is so much more convincing for movies.
