So then it looks like RC-62 is a must..Thanks Guys who commented !!!
The 7.1 to 5.1 in my opinion is just based on the limited source, Bluray although has released 7.1 and I have tried it with great results ,it just seems too hit and miss with new titles coming out with that format to really enjoy it, and I rather go with 5.1 but I paid only $75 for the pair of RB-10 so it's still a cheap option to keep up with the 7.1[Y]
