I plan to purchase my speakers September 15th and I am trying to figure out what to buy. Initiatlly I am going to go with 5.1 sound but plan to add the 2 additional surrounds in January 2010. I have an Onkyo 875 as my reciever. It puts out 140 watts per channel. It's a high quality reciever(THX Ultra II Certified). I am debating between the XF-48 system and the RF-62 system. I am confident my reciever will be able to power either set with ease. Which would be the better set of speakers to pair with my set up? I mostly watch movies on Bluray but my wife enjoys music more. Any advice is appreciated. Thanks in advance!
