The Smith Chart and...Power Cords
Just came across this video on YT today on the Smith Chart.
When viewing this video, it immediately became clear why aftermarket power cords can provide such an improvement to our audio systems. Here's an example what happens when the impedance of the "transmission line" does not match the "load impedance". This mis-match causes a "reflected wave" on the circuit, which you don't want to have, as described in the video. Note how the red dot is "off-axis" to the center-line of the polar plot. Now, when you have the PC's impedance matching that of the "load", you get a much more ideal response, as shown by the red dot in the plot, meaning, no "reflected wave", which is exactly what you want. And...this is one reason why well-designed aftermarket PCs can provide such an audible improvement in our audio systems: because they can "match" the impedance of the "transmission line" with the "load". In our case, transmission line is the PC from the wall AC receptacle, and the "load" is the FWBR* power supplies inside our amplification components. Don'tcha just love...SCIENCE? *–FWBR: Full-wave bridge rectifier

Ok, you've got me, haven't the slightest clue on how to read it but sounds good to me. You are definitely our resident scientist!

Um, well, at least one of 'em, maybe. I think most of the gang here already knows that, though.
Just two of my publications in peer-reviewed scientific journals (here as first author)... Gotta love...SCIENCE.

I guess I am too old to understand and it gave me a headache. I went and spun a Will Ackerman and that helped....!

While I have found power cords to make a substantial improvement in SQ, especially in all things digital, I wonder about the application of the Smith Chart at 60Hz as it was developed for use at radio frequencies (the lowest end of RF is above the highest audio frequency).
But, cannot argue with the empirical results of a good power cord.

I agree wholeheartedly. Common opinion has said standing waves at audio frequencies and especially 60hz line voltage don't matter. That said there is something going on that escapes me or I don't understand. I too have high end power cords that clearly make an improvement.

I have found significant improvements in using better power cords on all digital, and some analog. I am a firm believer in all of Wireworlds power cords. I placed a less expensive WW powercord on my Fanfare FT-1A Tuner and wow what a difference it made.
Now I just need to convince some of my local audio buddies that they do make an improvement. |
