I have narrowed it down to the kenwood and yamaha, and just want to get the most bang for my buck. From the main things I have seen the yamaha has these things that the kenwood doesnt, ability to transmit component picture effectively, and high current amplifier, built for 6.1 surround. (not sure what high current amp does). The kenwood has THX select, and 25 more watts per channel but not built for 6.1. So how big of a deal is 25 more watts/thx select/ and high current amplification?
