Hello Jake, and Welcome!
Since you are from England, it may be more cost effective for you to look into good quality speakers made in England, such as B&W or Wharfedale. I have a NAD 754 AV receiver and it sounds great with a pair of Wharfedale EVO 2 10's. The Wharfedale Diamond series are less costly, and have had very favorable reviews by experts, but more importantly,by actual owners.
