I'm fairly new to this audiophile-speak and I've only recently taken an interest in all things audio so please forgive any foobars on my part. I've been considering getting some decent speakers and a good A/V receiver to replace my feeble Philips all-in-one surround system. Kef Q's have caught my eye because not only do they look good but most of the reviews have given them the thumbs up for sound and build quality. I managed to get a demo of the older Q7's in a local hi-fi specialist today (much to my surprise as it's not easy to find a wide range of kit in small towns in Norway). To my untrained ear they sounded very good and better than anything else they had in the place. The shop didn't have any iQ's in though and it may be a while before they can get hold of any. No other Q's either. So, my question is how much different is the sound of the iQ's compared to the Q's? The shop has just one pair of the Q7's left (one with a damaged tweeter which they'll replace) and they are offering a 25% discount - are the new iQ's worth that extra 25%? My original thoughts were to get iQ5's for the front (or maybe 7/9's), iQ8ds for the rear and an iQ6c for the center. I'm a little concerned that this is will give the correct balance - especially if I insert the older Q7's as the front pair instead - or even the newer iQ7 or 9! I'm also somewhat concerned about my choice in AV receiver - I was thinking of getting the new Denon 4306 but will hold off until some decent reviews have appeared and I've had a chance to demo it. But I read yesterday that the Kef's stated 8ohm impedance is a little misleading as they usually run a lot lower even below 4 so will the 4306 be struggling particularly if I go with the iQ9 route for the fronts?
