Signal Flow Direction?

Just a thought... Why don't we laser etch the arrow in the shielding wire itself before the insulation is applied, this way it will be easier for the electrons to see them.
Sorry for all of the replies in a row... Just a little insomnia. -

I seldom post long quotes, but I thought this reply deserved a little recognition as it got zero above...howie777 wrote:The arrow points to which end the shield is NOT connected to (or that is the common way to do it). The reason to only connect one end is to prevent noise that is picked up on the shield in the cable from reaching the amplifier. So in a situation where you have a DVD player connected to a receiver, you want the arrows pointing to the receiver. This way if any RF or other noise is picked up on the shield in the cables it is fed back into the DVD player and to the ground through the power cord and not into the reciever where it can couple onto the audio lines and distort the signal which then ends up coming out of your speakers. This makes perfect sense to me as I have been involved in a lot of EMC testing in my time as an enginner and this happens often in testing. Now if you have a DVD player that isn't designed well, you could end up with the same issue if the noise has the oppertunity to couple onto the audio lines where the DVD player is connected to the cable in which case you have not accomplished much. And the same if the receiver isn't designed well.
So there you have it, a perfectly sound reason to use cables with shields and make sure they are connected properly. Mind you, if there is no noise coming into the system, it makes absoutly no difference, its just a precaution in case of unwanted noise. It shouldn't have anything to do with ground loop, if anything it would make it worse as you are extending the grounds not shortening them. If you don't believe me, well I don't care. I'm right and your wrong! (just kidding )
As for burn in, I was told it is commonly refered to as skinning which only happends at very high frequency, as in Gigahertz. Which is well above any audio signal. I tend to believe more of the research that says you simply grow accustom to the sound of new spearker/wire over time and that sound becomes your center from which you judge all else on. So it sounds better because that is what you are expecting to hear. Besides, speakers/cables degrade with time, not get better. That just doesn't make any sense to me.
Thing that gets me is that all audio devices step up the gain on the audio signal to some extent, so it seems that the place a given level of noise can do the most harm is where the signal strength is lowest. Howie, you mention design qulaity as a consideration, but what is inherent in an amp that makes design less of a consideration there?

Ugh, they won't answer my question about the y-axis % of their articulation response measurements. I'm thinking maybe its BS now. :mad: -
