Yesterday, after reading many threads here & on another Home Theater site I went out & bought a Phillips "High Definition Switcher" at Walmart for $19.95. I have 2 projectors....an Infocus 4805 & a 3M S10.....(it's a long story) that I wanted to hook up to my video gear (a HD cable box & a DVD player)& watch alternately. I used to manage a stereo store & have dealt with what we used to call "Tweaks" for many years. (Tweaks.......You know......the guys that claim they can hear the "skin effect" of certain speaker wire, etc) Anyway, I was worried that I would see (see is the operative word here)a degradation in the picture quality by adding a switch into the works so I was prepared to have to spend alot of $$$$ for a good quality component switch.(I have everything hooked up via Component Ins) I figured I would start out cheap, see how it looked, & then progress upwards ($$$$-wise) until I acheived the results I wanted. To may amazement....my cheap little switch seems to have done the job with no discernable loss of picture quality~!! Maybe my 58 year old eyes & ears aren't up to the task anymore but I'll be damned if I can see a diference. So let this be a lesson to all the normal people reading this & other Home Theater, Stereo & Video boards.......If you're gonna need an oscilliscope to see/hear a difference in any equipment you buy...You don't need it! If I cant see or hear it.......I don't want to pay for it!
