Sir. I also had a RPTV before in between my speakers. When I removed the RPTV in favor of the PJ , the improvement in music was very big since there was enough room for the music to move in the center. There was more depth and imaging was improved by a lot.
When audio listening , try:
1.) moving your speakers closer to you and away from the TV
2.) moving the TV away (its harder) and listen to your setup with nothing in between the speakers.
3.) If all else fails, Get a PJ.
Joke lang sir
hehehe
