Picture quality on compnents thru AV Amp

I'm thinking of running my XBOX and Tosh 220 DVD into my yamaha dspax620 as component ins (3 cables) then running these into my tosh 36zp18Q tv component ins.


Question 1- will running these thru the av amp result in a noticable loss of quality?

Will it be better than running an S-Video cable from the xbox to the TV thru the amp?

I don't want to buy the cables and find it will be worse!



Question 2 - Are component video cables the same construction as phono cables - ie will good quality phono cables do the trick or do i need to find ones labelled component?

Cheers

You will definitely notice an increase in picture quality moving from S-Video to component. I guess the question of signal loss will be very dependent upon the quality of your amp, the connections and the cables used but don't think with all the above being of decent quality that it would be noticeable.

As to phono cables, generally these cables are not designed for carrying video signals although I guess the more expensive ones will be OK. You need decent 75ohm cables for use as component but they won't neceessarily say component on them.

Re the XBox, to get component from that you will need the Hi-Def kit which comes with the component leads anyway. If you chip your XBox and use the Video Select CD you'll also get progressive output - gr8 if your TV can support it. Look in the Gaming hardware forum for more info on this.
