Just returned the second one of these to Richer sounds, the video switching is completely useless. Not only does the picture randomly disapear when using the svideo outputs, there is a blue hue all over the picture. I also noticed on the second one, a noticeable difference in picture quality when connecting a dvd player via component and connecting the monitor out component sockets to my display. That is the last time I by anything recommended by What hifi!! They tested the sound capabilies of this amp but not the video!!By the way I had the same thing with two completely new amps and three different sets of high quality cables. My advice to anyone buying one of these would be to get it from a shop that will allow you to test it first!!
