Putting aside that debate (and, certainly rbbert can speak for himself), his initial question was as follows:
Agreed.
Ron, I'm not going to tediously dissect his posts but his later posts shows his intent - the readers will decide, I'm sure. If this is just about winning an argument, rather than any search for knowledge, learning then it's contrary to your stated intent & somewhat disingenuous.
Against my better judgement I will throw in a bit: Ethan is of course right that the $5 power cord will do the job of delivering the power, in the world of of it being a power cord. But every electronic part is also other things, like a filter, like an aerial. Because, they are made of real materials, they are not perfect electrical components, that is, straight lines on a schematic, as the power in is depicted in an electronics textbook.
Yes, Frank, the real world is a dirty place, components can have more effects than their stated function & getting the best from our audio systems requires that we deal with this dirt & non-ideal components. This is the complexity that Ethan seems to miss or chooses to ignore.
Tediously dissect his posts? Really? I quoted his request above. It is for all to see. 2 sentences. That is tedious? At the same time you want readers to visit another website and read pages and pages of another thread (which, BTW, I followed at the time it was happening - I've been following John's posts for years and even invited him to join us here at WBF which he then did). So please don't call me disingenuous.
No, I have no experience with them. Indeed, to the contrary, the last thing I remember posting in that thread was that I hoped they worked inasmuch as I am in favor of anything that raises the bar. My interest in that thread is the same as it is here, to-wit: promoting an exchange of ideas so that I and, hopefully, others, can learn. Anecdotal evidence need not apply, however.
Good god, I knew this would become a point scoring exercise rather than any attempt at discussing interesting topics. This is exactly why I'm suggesting your statement early on about how privileged, etc, etc appear now to be disingenuous. You are more concerned with point scoring than discussing anything of interest!
Great so you know what valuable information is contained in John's posts in that thread? The post I linked to is all that's required to be read to get the point I made - if people want to read the full thread that's a choice I would support
Great on the Jneutron front! I've dealt with the disingenuous bit above
Sorry, my mistake, I mixed you up with P. Ponk's quote "The difference between a tweaked digital interface with a battery power pack and the original, unmodified model? That's worth blind testing."
Ah so do you only want measurements or is discussion of theory ok? blind testing results ok? sighted listening tests ok? reference to papers OK?
The normal measuring techniques are not going to pick it. So someone has to devise an appropriate test signal which will "exercise" the equipment in a fashion to expose the weaknesses, which will be impacted by the choice of power cords. A good one will be a mix of a high level bass frequency, and 2 low level midrange to treble frequencies separated to suit an intermodulation distortion measurement. The bass note will severely stress the power supply, causing the IMD to do all sorts of interesting things ...
