Hi,
In regards to your question, I was running Monster video 3's and recently switched over to the zu cable megular. I noticed that the zu were not as good initially because they had not yet been burned in (Still burning in and I'll need to retest afterwards). however, I feel that they don't really make a big difference if you are within the $100-$200 range. I've also tested the wireworld starlight S-video cable. that was a bit better than the monster video 3 cable but it's also more expensive. If you are really serious about upgrading I suggest the audioquest YIQ5 I've heard that these are one of the best.
