Thanks for the responses. I have found a local shop where I can demo the two side by side this weekend. Most of the user reviews I have read on the Rf-3's have been really positive, but the professional reviews I've seen have been mixed. One really unfavorable review stated that the center and surrounds don't timber match real well with the mains. Can anyone comment on this? The review can be found here:
