I CURRENTLY HAVE A 5.1 SPEAKER CONFIG. WITH NO INTENTIONS OF UPGRADING. WOULD A RECEIVER WITH PL2 AND DTS NEO 6 BE BENEFICIAL OR A WASTE? WHAT OTHER FORMATS WOULD BE BENEFICIAL WHEN SHOPPING FOR A AV RECEIVER. ABOVE WILL BE FOR TV AND DVD VIEWING PRIMARILY.
The NEO probably would not be that important but PL2 is good for watching t.v. or VHS movies. Some people use music PL2 for listening to their music but I don't like it. Just make sure that the receiver has dolby digital and dts. Those are the main formats.
