A challenge to the "measurement" camp

I’ve watched some of his video and I actually agree on some of what he said,
but he seems too confident on his insistence on measurement. For those
who expound on the merits of blind test and measurement, why not turn
the table upside down?

Why not do a blind test of measurement? That is I will supply all the measurement
you want, can you tell me which is a better product?

For example, if I have a set of cable, and a set of measurement for each
individual cable, can you tell me which is the best cable based on measurement
alone? I will supply all the measurement you want.
After all, that is what you’re after right? Objective result and not subjective
listening test.

Fast forward to 8:15 mark where he keeps ranting about listening test
without measurement.

By the way, is he getting paid by Belden?  Because he keeps talking about it
and how well it measures.  I've had some BlueJean cables and they can easily
bettered by some decent cables.

speedbump6,

I also assumed that Gryphon people do use expensive cables, why wouldn’t they? I also suspect that Pass amplifiers rarely get connected with lamp cord. Those are assumptions and suspicions/guesses. I am quite convinced that difference in my preferences may be due to more things than cables. Maybe even the room.

I watched the video,  didn't tell me anything new but he didn't seem as annoying as I remember from other videos. Another guy that I find annoying is the PS Audio guy. Not saying they aren't smarter than me or don't know their stuff just don't care for their YouTube shows.

The GR Research guy knows his stuff on some things, not on others. Paul from PS .... ya, those are mainly marketing blurbs and miscellaneous ramblings.


When you hook up an expensive power cable to your Power Regenerator, and then claim that it sounds better, the natural inclination of most engineers would be "what did I do wrong in the design of my power regenerator", not "wow this cable is awesome".

Any power regenerator will introduce a noise of his own making by the mere presence of his electronic components...His design is the results of a wise trade-off  created by the original designer...

If we introduce this power regenerator in a particular audio system with a noise floor of his own, adding to it a power cable then  modifying this particular trade-off,  would it be unthinkable that a power cable can improve  the original trade-off or destroy it in some case?

It is a question.... I am in no way an engineer, or even a scientist....

Thanks....

mahgister,

The whole point of a power regenerator is to decouple the output AC from the input AC.  PS is claiming changing the input AC cord significantly changes the sound.


If that is the case, then their device does not do what it is supposed to do.
