Actually, on a 60" you notice the problems with the picture, to wit NTSC was designed to be displayed on a set with no more than a 20 inch diagonal.

Perhaps his "different" could be better to him when all those messy dynamics, and punchy bass, are reduced by using CAT5 for speaker wire. As mentioned, as soon as the criterion is "different" and nobody is listening to see if it is better, then there can be no real argument.

We are going for better.

And I agree that once you get rid of the garden-variety (I call them garbage-variety) cables, the slim giveaways that come with many components, you are likely to see and hear the most dramatic improvements in the first twenty to fifty dollars, and very little improvement after that. For that matter, very little change (again, "different," not considering better or worse).

As to selling cables because the client wants them because they look good, WATCH OUT. You have dropped your own awareness of the fact that people want sizzle on their steak, and you are not even talking about the steak. Since you are in the steak business, remember to add sizzle, but be sure you are not putting sizzle on a (add your own crude term in this space).
