Interconnect Directionality

jetterI have no ideal why what I believe is a small group of persons on A'gon would think that blind testing won't yield fair and impartial results. Please do not repeat the GK arguments against it that the testers are going to rig the test.

Nothwithstanding the fact that the conclusions are sometimes dubious, there have been many perfectly valid listening tests. Because it's such a time consuming task from the onset, organizers who actually go to the trouble of conducting such tests typically put extra effort into making them valid. That's pretty well established.

I am willing to test on any system you wish to configure ...

Let's see if the group can agree about what that system might look like. Then you could try to assemble something comparable at one of the major audio shows, and invite Audiogon readers and others in to participate.

The crap is where the details are jea48:

- Buried in some ... probably a lot of my messages back and forth with Geoffkait was that I was specifically referring to, and I used these words, analog audio signals and "non time dependent digital signals". I used those words very specifically as most DACs today either reclock the external optical or digital serial audio data and/or they are USB based and hence generate a local clock for audio. I specifically took time dependent digital signals out of my discussion, because as I clearly stated above as well, MHz level digital signals have 10's and 100's of MHz bandwidth and hence are subject to transmission line effects.

Let's add the most obvious reason in the case you provided, RCA connectors are not controlled impedance connectors which is why most good equipment has BNC connector now. (p.s. probably even before that article you linked was written, I was modifying my equipment to better match source/load impedance to the cable, a specific cable, to minimize jitter). DACs were not nearly as good back then. 

AND, I never said the energy travels back and forth from source to load. That is how you are interpreting it, and that is wrong.  I said it travels both directions in the loop, and that electrons flow through the whole loop, which means they are impeded by and pass through the interconnect (or fuse) in both directions, equally, outside of transmission line effects, which don't come into play at analog audio frequencies coupled with SNR and mismatch timing/amplitudes. I will throw in that skin effects in any tolerable cable at audio frequencies, SNR, loading is also a null proposition w.r.t audible differences.

Here is the thing jea48, the claim, at least from MFRs, many users are more honest, is that they ALWAYS improve. My $100 one is good, $1000 amazing, and $10000 totally stupendous, and you have to admit MFRs and users make these claims.

Tell me, how do you match said cables to equipment that has tolerances in the few percent range? .... and claim "always better"?

Care to start a thread? I don't mean that facetiously. As I said, I am willing to fund, it, but not all of it. I think we would need local assistance for good quality equipment. I can think of a few in the industry who would help with things like ensuring the acoustic treatment is done well, speaker placement near optimum. I would not want to enter any of my potential bias into it.

We could start a GoFundMe. It either dies on the vine, or it goes through. 

Count me in!
