My Yamaha receiver is now 3 years old and was one of the first on the market to have a Component switcher built in, it has 2 inputs and is rated at only 29 MHZ. According to the "Gurus of HDTV Component switching", you need something like 60 MHZ. This is nothing but pure BS. I have compared my picture quality going direct vs going through my Yamaha and their is absolutely ZERO picture degradation.
When Outlaw Audio created their latest and greatest preamp, they did some signal testing with HD and found that anything above 60 MHZ can actually introduce signal noise. I think they decided on something like 45 MHZ for their gear.
Now that I have more devices than inputs I just ordered the
Audio Authority 1154 4 component switcher. It's a cool box, it learns your habits and you can prioritize the inputs. It will also pass digital audio, composite video and analog audio and comes with a remote control. I just got it yesterday and will be hooking it up this weekend.
