Howdy, Does any one have firsthand Sonic, Listening, and Impression Differences Between the RC-7 and RC-64 Center Channel Speakers? I realize it is easy to say the RC-64 is better......but why? Is it truly worth the additional monetary investment? I presently own an RC-7, RC-62, and an Academy. I would be pairing the center speaker with 2 pairs of RF-63 (Front and side speakers) and either a pair of RB-5 or Forte II for the back speaker duties. Thanks you to all the Forum Members for your input and advice. If I decide to buy the RC-64, I will sell my RC-62.
