What is the meaning of 'cable FR' ?

OTOH, the HD650 seems to benefit greatly from killer wires...so maybe it's just a beyer thing. anyway, I fully understand why most ppl think that recabling is snake oil.....and when Denon boasts about 7N-OFC wire on their high end cans, it means that they actually took the wire impedance/resistance in account while engineering the drivers [size=small]playing god w/ mismatched cables is a big no-no! on beyer cans at least...[/size]IMVHO YMMV etc PS: this post is very interesting too : http://www.head-fi.org/forums/3160410-post13.html the purer the copper, the bassier!

interesting conclusion you have drawn there, from your scientific experiment.

 

[leeperry]

well, do some experiments on your side...let us know the results

Really? Wow! I guess I haven't learned anything in the last 25+ years of designing wire and cable and everyone who has purchased the Twcu and uses it as their *reference* is listening to crap and they can't hear!

Hey, if you don't like the wire, that's cool, and I am completely fine with it. Everyone hears differently, values certain aspects of sound reproduction over others, and has different priorities. And, that's part of what makes this fun and keeps me interested and designing new stuff. If someone doesn't like my stuff, cool, there are a lot of other great manufacturers out there, one of them is making what you want.

However, to call the wire "crap" is not cool. Especially based on your limited testing of it with one sound card and one pair of cans.

I wouldn't mind piping in here and just commenting that the OP's technique here is very hit and miss, and feedback/results vague and unfounded. Nuances between cable making designs and materials are just that, nuances. If you build it one way and don't like it, there could be a lot more to it than saying the wire must therefore be crap. I also question the fact that the feedback has been given almost as soon as the cable(s) were finished - so how long were they auditioned for exactly?

 

[AudioCats]

come on guys, why such seriousness? This is mostly meant to be a tongue-in-cheek entertainment thread, haven't you realized?

just have some fun, cheers

OK, time to unwind, drink an "adult" beverage and get rested up for another day of CanJam tomorrow!

Having a blast at CJ '09, some really great people here.

actually, calling it snake oil is not very accurate.

I might try to rub the cable w/ a serum made of snake venom extracts : GARANCIA The Botanical Alchemy of Future: Cosmetic Care composed of natural assets, BIO, High-tech

Patrick82 recommended it to me, that's how serious I am!

of course I'll let you guys know how it does on my face too

PS: I didn't call it "crap", I was merely quoting my EE friend's words...I'm sure it'd do wonders on an HD650, or at least pretty sure

I realize you need a $5000 amp to make this cable sound good, shame on me I guess

I only let it burn in for a few days, prolly after a month or two it would have given on my poor equipment...only god would know!

 

[leeperry]

the first tip on that page talks about "signal polluting dielectric" : Stefan AudioArt Home
I'll have some of that, if any possible

 

[AudioCats]

I like your EE friend, can you please ask him to explain what exactly the " if the cable FR has changed, then it means that the wire doesn't have a null impedance.." mean? "Null impedance" is a new term to me.

Of course, he probably never really said that, you just understood it wrong or the true meaning was lost in translation, or something like that.

 

[leeperry]

yea, I'm a dumb foreigner..sorry for that

 

[AudioCats]

I thought this is an international discussion board, there is no such thing as a "foreigner", everybody is the same

really, the "null impenance" theory is very interesting. Would like to know more about it.

 

[Bonthouse]

It means zero impendance. No impendance, nada impendance. It isn't a translation error, I hear Americans and English folk use it all the time.
