1st thing that you need ti figure out is if your setup will be used for ht only or ht+music. If HT only then I recommend Onkyo receiver and a warm set of speakers like mission, wharfedale or even b&w. If ht+music then marantz receiver and bright set of speakers like polk audio or jbl. For subwoofer, I cant think of any but SVS. I recommend listening room in mega and watts hifi in mcs for auditioning.
Audition is the key as we have different listening preference. The more you ask, the more you'll get confused. Audition and listen is the safest and the best way to go
