My cable test enterprise - Page 2

Could you measure impedance/resistance/capacitance etc?

It would be great if it was possible to do waterfall plots and things with headphones. Would not be easy though!

Looking forward to the listening tests!

From what I've read, for the most part a "perceived" change in volume usually occurs when the volume changes by 3 db. In a very quiet environment where a person is specifically listening for volume changes, a 1db change can be heard (by some people).

The drivers of the HD650 are matched to 1db. By what has been discussed on this board, the HD800 is matched to 3db (+-1.5 db). I assume Sennheiser takes the stance that drivers matched to that tolerance will basically be perceived as having equal volumes.

Keeping that in mind, .05 db is minuscule. I'd be very surprised if anybody could hear that small of a difference and would not believe such a claim unless there was a solid double blind test supporting such a statement.

R.E.S.P.E.C.T. Looking forward to your listening tests. I always think about the coat hanger test.

I actually dont think this tells us anything about the way that complex variables interact with each other to form 'character' and also since you havent actually tested a cable that I would even consider buying, it doesnt really mean a great deal to me. thumbs up for the thoroughness with which you tested one variable among a range of fairly average interconnects really i'm serious, but I have my doubts as to whether you can actually put together anything meaningful, that can illustrate how we as humans may interoperate a change in dynamics, or PRAT. perhaps you should extend this testing to amplifiers, caps, resistors etc. if this test truly tells you something, then your logic should be able to be applied to those too; since all amplifiers at or above a certain pricerange or quality of construction should all sound the same too; since they all operate above the range of human hearing

Well done! Thanks for your efforts.

Everytime I have "heard" a difference in cables, I swapped back and forth a few times and discovered I had fooled myself. The cable money now buys me music, instead.

Those complaining that the tests don't prove anything because he isn't using cables you would buy anyways should be the first ones to offer them up for testing.

Unless you wish to possibly remain blissfully ignorant (and poorer) you should be jumping at the chance for him to get a true sample of high end cables. He's doing a lot of legwork I doubt many people on this forum would even consider, let alone do.

He chose to get a few mediocre cables instead of one high end cable and comparing that to his own cables. You also forget one thing, it doesn't benefit me or anyone else who know what cables can do to the SQ, the only positive thing that could come from all this is some of the people with their heads buried in the sand might realize they are wrong and get some enjoyment from a good cable. We are talking about people who spend hundreds or thousands on headphones and amps and sources right? I hope he does hear a difference between the AQ Sidewinder and a Rat-Shack cable so he doesn't create an even bigger bunch of mis-informed people than we already have. The proponents of using high end cables to enhance sound quality are fighting this because we want to share a discovery, if you choose to stick your head in the sand then so be it. You guys don't really think for one second that I care if you purposely limit your audio system so you can run around telling others that the world is flat do you?

Will I send my 240 dollar IC's across the pond for something like this? Nah, if something happened to them in getting there or comming back then what? Take advantage of our experience or dont. Send all the current test subjects back and get one high end cable (Silver if you REALLY want to hear a difference) and see how that goes.

Flame On

Since when did I state my position in that post? I responded to those who are ignoring his test simply because he can't afford to test high end cables. If they want to know results they will need to have their cables tested. It has nothing to do with my personal beliefs.

I personally haven't heard a high end cable yet, nor has my system stabilized to the point where I would actually be able to tell a difference. Once I can spend 6+ months with the SAME gear I'll be able to tell. Actually, looking at my setup presently I'll have solid silver xlr ICs ($100ish) made by mmwwhats that Headphoneaddict suggested to me that closely compare in his opinion to some custom ALO XLR cables ($600) he got made for him. I'll also have an APS V3 headphone cable ($230) so I will already have fairly premium cables as it is. The headphone cable was one I had to have since there is no stock XLR 4 pin to Sennheiser jack cable I could buy. The XLR cable was bought on a whim just because it wasn't too expensive and it was recommended so I went for it.

So don't bring your argument to bear against me. You won't see any radio shack cables on my gear.

If you can do it with insurance what is the risk? (Though I don't know if insurance is available internationally)

edit: On a side note: It seems like the proponents of high end cables are intentionally against testing. Believe what you wish about your cables, but what is wrong with testing them? You guys (I am neither for nor against) remind me of Patrick82 and his $25,000 power cables to his $200 DAC. If Patrick says it makes a difference what is there to distinguish your views on cables making a difference from his? With no hard evidence it becomes nearly impossible to discuss on a broad cable-market wide platform. You limit yourself to specific cables and situations making it damn near impossible for anyone else to have a clue what you are talking about.

I am pretty new to the "high end" cable thing. I used alien DAC+pimeta+K701 once to test two silver cables I have. One was a fully burned in signal silver cable, the other was a new DIY solid pure silver cable. The signal cable sounds much warmer than the new DIY silver cable. I don't want to argue with anyone by saying one IC sounded better. just like I am able to tell my DV336i sounds warmer than pimeta with K701, I was able to tell signal cable was warmer. Since that comparison, I started to believe in burn in and cable effect on SQ.

Sorry if I was jumping your case. Im not against testing, I just want everyone to know this isnt about winning an argument and that I hope he finds differences because my experience has shown me that they can improve or change the sound quality. Were you able to listen to the 650 single ended with the OEM cable and then with the V3? If you did then were you able to notice a change in tone? I had the V3 and for me it made the entire mid section come forward.
