I'll strongly recommend that Serwood 4105
I know four people who have been using Sherwood 4105's, some for many years now, with no trouble and nobody, even I, can find fault with their performance.
As for the speakers/sub combinations, one of those 4105's is using that Polk sub wit a pait of small Polk bookshelf speakers and it sounds quite nice, particularly considerig the whole setup cost her about $280. I should know. I told her to buy it and I set it up for her.
