AVRs in same price range come with similar features and properties, except few brands which have higher cost than others like Marantz.
if you go to any dealer and take audition for these AVRs in well setup room, then you may not be able to tell the real difference, if any. One of the reason is because your focus gets distributed between audio and video. However, you may feel some difference (if any) if you setup those AVRs in stereo mode for listening music.
This is what my experience says... at least.
Pioneer 330-k is good for entry level setup in my opinion, however I would suggest to avoid the entry level products of any brand. They often compromise on things like build quality, connectors/binding hardware, SQ (may be).
If you can go for one model above, then it may keep you happy for longer period.
