RE your post at:

http://www.audioasylum.com/audio/cables/messages/15/156041.html

where you state:
"I just read a post where the OP was wondering if replacing the cord on a conditioner would benefit the sound of his system. Since you can't post anything contrary, all the OP is going to hear are positive comments. What good is this?

What would happen if someone with an advanced degree in EE posted results of DBTs to the contrary?"
-
With regard to your last sentence above, the problem is, DBT results CAN NOT SHOW SUCH A THING.
A FAILURE TO REACH A STATISTICALLY SIGNIFICANT RESULT DOES NOT MEAN THAT THE RESULTS EQUAL A NEGATIVE RESULT.

This is the science of statistics, and I continue to find it amazing, that folks who claim to embrace the mantle of "science", completely ignore the true science they claim to respect and believe in.

It would mean the your "advanced EE" was pretty lame at statistics, and didn't really know his way around DBT's, and therefore, pretty much everything he posted on the subject would automatically be suspect as utterly worthless and useless. Including any sort of "results" from a DBT of questionable value and precision.

I think that most all of the Cable Asylum posters welcome the refuge from objectionists and naysayers who feel compelled to continually try to "save" subjectivists from themselves, and their "faulty" ways of evaluating components. No one needs saving, no one is being harmed, and no one has to post or read content at the Cable Asylum if the fundamental premise of the Cable Asylum bothers them in any way.

The vast and overwhelming majority of folks who object to not being able to denigrate people over DBTs, sighted listening, et al, are merely interested in stirring up some trouble and starting a flame war.
Hence the no-DBT rule at the Cable Asylum
http://www.audioasylum.com/cgi/d.mpl?audio/dbt.html
re DBT postings.

The 1% who really don't mean to start trouble, invariably back off and respect the rules and format of the Cable Asylum. Those who don't are quickly determined to be nothing but trouble makers, and are banned.

A few folks seem to be unaware that I myself have conducted a great many blind controlled listening tests, and gotten positive statistical results.

Annotated Cable Bibliography

Hardcopy Books & magazines

Duncan, Ben & Harrison, Andrew; The Great Cable Test (part 1), Hi-Fi News and Record Review, July 1999, p.30-33, Vol. 44, #7

Duncan, Ben & Harrison, Andrew; The Great Cable Test (part 2), Hi-Fi News and Record Review, August 1999, p.32-41, Vol. 44, #8

Duncan, Ben & Harrison, Andrew; The Great Cable Test (part 3), Hi-Fi News and Record Review, September 1999, p.40-53, Vol. 44, #9

Comments:
The above three part article is a landmark series, as Duncan and Harrison show that Speaker Cables have a dynamic phase shift with a change in signal level. Phase shift is nothing new, and many have supposed that phase shifts might be a portion of the reason cables sound different from one another. However, the measurement results given in these articles is noteworthy because it shows that speaker cables are definitely non-linear components. A given loudspeaker cable's total amount of phase shift changes as the signal level changes.
This means that FM is present, and an effect sonically akin to digital jitter is occuring within speaker cables.

The fact that this is occurring in speaker cables means that it also must occur, albeit at a reduced level, in interconnects as well.

The article also contains listening test of all the cables tested using the new measurements, which also include a high resolution transient test measurement, using the leading edge of a square wave.

Lloyd, Jim and Overhauser, David; "Electromigration wreaks havoc on IC design.", EDN magazine (Electroninc Design News), march 25, 1998, p. 145-148
Comment: Electromigration is the mass transportation of a metal resulting from the momentum transfer between conducting electrons and diffusing metal atoms, and exists where ever current flows through metal wires. This provides another scientific and physical basis for cable conductor break-in effects.

Comment: This is an excellent physics reference and contains information on many of the more esoteric parameters related to cables, as well as the basics.

Deletraz, Herve: "Reflections, Echos & Music", Stereophile magazine, Nov. 2001, p. 59
Comments: While there is much to criticize with this piece, I feel that it has two bits of information that should not go unnoticed, they are: at HF's, impedance matching is very much a requirement, and that the 'echos" of unterminated cable reflections may go on for a lot longer than we ever thought.
Given the unterminated example in his article, we can only see what is occuring for about 40 dB down from nominal level, everything below this is lost in the trace display. If we look at how long the unterminated reflections may continue on down to a -90 dB level, then it become apparent that the window for signal disturbance is much wider than the 5-6uS we can see in the display window he provides in the published article.

Thanks for alerting me to this. I think the way you have cables is a pretty good idea, really people are going to believe what they want and it cant be changed with a couple of forum posts. After peeling the onion a bit further though, I hafta say I'm rather astonished that a person would actually spend more on a cable connecting speakers and amp than the speakers and amp cost. That one is just beyond me.

Price to performance is not linear, as we all know. Some components play way above their price point. My PM1's provide as thrilling a ride in my sitting room as my Wilson 6's or Dynaudio C4's did in my large family room and my C375BEE with MIT cabling and AC2 PC delivers close to state of the art vs my Krell Evo402 or AR VT200...just to name a very few examples. My Denon Anniversary SACD player rivals my Levinson No. 390s and Krell 505SACD. The room and system synergy and actuall dynamic performance should determine what one spends within any given budget. Bias towards the extremes is ignorant and misguided on both ends, whether it be the "Prop head/DIY it all sounds the same" crowd or the "I've gotta have the most expensive cool looking kit" morons. It's personal, it's a hobby and to each his own. To make a cult out of it is insane. Just enjoy the music your own way and let it be! Of course as I said before, all this pseudo intellectual drivel doled out by ostensibly well meaning people, can be easily avoided if you just "try before you buy" and trust youself. Now go forth and get that $25 ultimate IC you've been saving up for....or maybe the $2000/M one in the window at your local dealer:O)

Your argument would almost be compelling if you didnt tout MIT cables in vityually every post you make ;-)

You can believe what you want. I presume at the same time it might be okay for me to believe that anyone who plugs a '$1500' power cord into a $1200 integrated and pronounces it miraculously transformed to state of the art takes in a bit too much caffeine.

Why thank you finski, I'll consider that a compliment coming from you:O) I do keep an open mind actually, but what I can't relate to you completely is the countless years of system building, cable matching and exhaustive listening sessions comparing said gear. Just because I don't currently sport any one of my Mega systems, should not minimize my findings. Scaling down was a choice I made for my family and for myself in a way. I find it more satisfying listening to gear that has high performance per dollar and is more readily incorporated into my living environment. The 2 way PM1's also bring along a certain purity that is hard to attain from a multi way system. The MIT cables ARE my favorites, but not out of audiophool blindness or hype or advertising. I have owned much of what's available, from the $100/M stuff to the $12K/M wires. I was fortunate to have some of the best gear, but that didn't keep me from experimenting and doing trials, trying to learn first hand about a hobby(equipment)that most people only read and drool over. As I said, I came across the revelation of using High End cabling on my meager setup(still runs around $20K all total)by default, since I owned the wires already from my previous State of the Art kit. Believe me, I would rather sell them off, but they truly raise the level of performance from the mundane to the exhalted! Truth be told, I still use a couple of Audioquest PC's to feed my source and my tube buffer....they just seem to deliver the goods so why screw with it? What I've learned is that everything matters in a system and experimentation is the only true way to happiness. Some gear may be high value....other synergystic enhancements may cost more. Blending them is an art form and will never be correctly determined by any measurements or ideology. Sometimes however, you may find an exceptional group of products that repeatedly outperform the field, and when you do.....you tend to gush:O) Happy listening finski and all the best!
