There are numerous hifi manufacturers that make separate pieces that can be assembled for a very good system. However, the cost could be prohibitive for some.
Receivers of good quality can sound good, and provide a very good listening and watching environment. I would be inclined to say "if it sounds good to you, it is!". You may require greater power, newer features and expansion after using your system for a period of time. On the other hand, this may be your Xanadu!
