Upgrading Fuses

Ghosthouse - Milpai

Fuses.
Not, wonders of nature, magic and mysticism, limits of the universe stuff.
Just lumps of metal that you pass current through & that have a limited number of properties that are easy to measure & quantify and understand.

No rocket surgery involved here.

"Payed" (sic) magazine reviewers like Robert Harley and John Atkinson have written extensively about how measurement methods are routinely being developed that enable us to explain things that people hear which could not have been measured or explained in the past.

The best example pertains to digital audio. In the early days engineers were outraged by people who claimed that all digital playback devices were not the same. Some engineers pointed to their spes and said that CD's provided "perfect sound", Zeros and ones are zeros and ones, they argued. The measurements show that what goes in is exactly what goes out.

Then jitter measurements were developed and, lo and behold, it was discovered that the lowly listeners had been right all along. Digits are not just digits and all cd players are not equal in terms of sound reproduction quality.

People like Harley and Atkinson contend that it is not measurements that are the problem; it is people who worship those measurements.

But of course these two gentlemen are not geniuses like Metro04.

Don't you have any other friends to play with? Try your best to comprehend what I'm writing this time. That way you can hopefully do a better job with accuracy in your interpretations of my postings.

"I'm a bit surprised that you're willing to bet money on an unsubstantiated opinion that Conrad-Johnson has measurements to support all of its design decisions. Please post the supporting document!"

>>> What "unsubstantiated opinion"?!! CJ, like *just* about all major audio equipment manufacturers, employ engineers that design and thoroughly test their circuits which may incorporate whatever topology and quality components to achieve their design goals! The proof is in their measured test results, data, etc. and verifiable by anyone (buyer) with appropriate test equipment! If CJ is willing to share their measurements with you, hence your verification, thus NOT an "opinion"! Understand the difference?

Vhiner: "Now, back to my main question: could you please post the academic studies you consult before you buy your equipment. I'm eager for the bedtime reading."

>>> Every piece of my audio equipment has documented specifications from the manufacturer, all of which are verifiable via test equipment measurements, thus holding the manufacturer liable should results not match based on their testing criteria. Same goes for most electronics in general besides audio.

Now, I'll ask you again! Where is all the documented test results or written specifications from the manufacturer's of your fancy fuses? Gee, why is it that they don't offer any? What about the ever-growing list of exotic cable manufacturers? ...Printed specifications for performance attributes other than wire gage and plug specifications? Hmmm, yeah!

Metro04,

Thanks for being so patient with me. Are you saying Conrad-Johnson has data proving and explaining that it is in fact the teflon capacitors that cause their equipment to sound different from their competitors' equipment? It could be that they do, but unless you can provide that data, your supposition is unsubstantiated. At least that's what unsubstantiated means according to my silly old dictionary. But if substantiated fact actually means anything you happen to say or suppose, then I think I understand. No one wants another "pure unsubstantiated opinion" ticket from the Truth Patrol.

As for your use of the word " proof", well you really have revolutionized the use of that noun. Again, I apologize for being so slow in comprehending the new definition and application. You have demanded academic studies in past posts. I'd like to read some that you've used in your equipment selection process. I've been reading far too many "audio" publications which you've ridiculed, for good reasons I'm sure. Please give us your top ten academic journal articles (citations would be helpful) so we can share the wealth.

Paul McGowan just wrote in his PS Tracks blog on Wednesday that, "Two amps that measure the same don't sound the same." That's odd. People who aren't blessed with your level of genius might conclude that Mr. McGowan is implying that some sound eludes current measurement tools. But, again, I'm sure your background, training and ethics are far more "pure" than that of Mr. Gowan, Mr. Hartley and Mr. Atkinson.

Vhiner... "Measure" the same.

As I have pointed out, the human ear, which we all agree is the ultimate judge of how it sounds, can be used to make a measurement of any difference between two audio amps by listening to the null across the hot output terminals. Since "difference" is what we are interested in it makes sense to measure (listen to) difference. Small difference is almost impossible to objectively detect in the presence of the strong signal. "Almost impossible" opens the door to subjective opinions as we see in this discussion.
