Well you don't give a budget, but I'd say with this amp you're looking at a package between about £2k and £4k in order to utilise the amps capabilities. At the lower end you'd be looking at something like the Monitor Audio RX6AV package, or a package based around KEF's Q500, or more ideally, their Q700 with that size room. Moving up from that really depends how much you want to get out of the amp as far as music is concerned. Either KEF's Q900 will be a good start, which use KEF's first 8" UniQ since the original Q Series back in the early 90's, or, as Nick states, something based around one of the PMC models. I'd add to that either KEF's XQ series, Monitor Audio's Gold series, or a package based around ProAc's Studio 140.2 model. First thing to do is to book a demo and try a few of these speakers out with the 3008 and see what you think of them, to get a feel for what the combination is capable of, then try the whole package to make sure you're happy with it.
