Hi all I have a question. I own an Onkyo HT R530 receiver. It's your basic 7.1 1000 watt set up which decodes all of the standard audio formats. I have Polk Audio (RM-20 series) speakers and sub. I also own a Blue Ray player and I am an avid movie watcher. The system sounds great but, I am considering purchasing the new TX SR705 from Onkyo. I want the capability to convert PCM, DTS-HD 5.1 and Dolby TrueHD. Do you all think the sound quality is that much better? I just wanted more opinions before I dropped $700. Thanks. Brian
