There are only 2 possible changes, timing between the 2 speakers and the frequencies produced. If the timing is the issue, you'll need need to use a computer to start and stop the playing and the recording of the channels independently. The recordings have to be done at listening position, and you have to make sure that you do them consecutively. You want to make sure the temperature and humidity are about the same between both recordings. If the change in signal is occurring at the IC's you could just pipe that directly into the computer and compare at the signal level first. Do you know the voltage level of your preouts? However, if it's just a difference in the sound and not the timing then you should be able to identify the problem by listening to a single speaker.
The pre-outs should be far less than 1V to drive the amps. I do believe it is timing related, therefore corrupting the exact location, the strange part is that the strings still sound as focussed as on the other set of cables.
I have to go out for work quickly, will be back later.
Yes, ears defy physics by being able to perceive sounds as if they were in a totally different physical space. You're still running into the nulls and it'll still change your perception of the reproduction. Just because you have 2 ears doesn't mean you can move your head and hear identical results. This comment is simply moronic.
Do you hear the character of voices around you alter dramatically when people move an inch?
You'd have to do it for each listening position tho. That's where the ambiguity of the question creates a problem. What does he mean by whole room?Yes and no - depends on what "one take" means. We percieve the sound of the room as temproal and directional arrivals of impulses. A single mic cannot sort out the two things, but a four microphone array can. So the answer is yes with four mics, no with one mic.

Nope. Nor do I hear their character change with wire, either.
Yeah, you've never turned your head a little to hear something better? We naturally keep our heads aligned during conversations with the people we're trying to talk with. It's not conscious, but you frequently make corrections to try and hear conversation better. You also bend your head down (or turn your head away) when something's too loud. Your own body knows small shifts have major impacts on our perception.Do you hear the character of voices around you alter dramatically when people move an inch?

Oh, I'd like to add, the character of the voice doesn't change as much as the volume in those situation. The volume is because of the shifting in the perceived nodes of the environment. If you're talking about a character change, you're talking about a change of environments all together. You can hear over the phone when someone is talking in the bathroom or in the kitchen or under a blanket. All because of changed to the nodes excited in the environment and the frequencies dampened by the surroundings.
What does he mean by whole room?
Wish I knew
But nice answers, thanks
I was asking myself if what we hear in a room is the same as splitting the room up in mathematical local ressonances, or measured, and then put them together in a model
Or whether we actually connect all these acoustics in a different way, and experience all these acoustic room details in a much more complicated way, when listening
I understand that a major part of room ressonances and issues can be mathematically explained, but maybe theres just a bit more to it than that
I know we can model these structure in any way we want, but is that really HOW we experience such, when listening to music
btw, just a fun one
No so long ago I had 3ways with the strange effect that the soundstage focus followed exactly the direction I was looking in
Tho the soundstage focus on my now randomly thrown together OMNIs are rock steady, and precise, unexpectedly
This not to tease anyone, please no, just a funny fact I intend to follow up on, Omnis as room interacting speakers
Not fighting the room issues, but defeating them by integration
But not for playing very loud ofcourse
The later swedish Carlson tried it too, with some success, but not complete
But maybe it can be improved, or at least I think it can
Well, Im out
For some that tricking of the mind is already there 😉
Perhaps for those who claim they are only interested in "accurate" sound,and think they have the perfect systems to reproduce this "accuracy".......
kareface,
Since you and I are in Seattle and you are well versed in room nodes, would you like to measure and audition a pair of speakers that don't appear to excite room nodes, in the conventional manner, along with a close duplicate pair that do?

s when it comes to audio science.
So enlighten me on how you consider the ears to be more accurate then measurements and what is heard that is not measureable.
hey were the only tools used to make beautiful sounding instruments,that the scientifically perfect measuring playback systems fail even come close in reproducing their sound.

They "don't appear to excite room nodes, in the conventional manner" but "a close duplicate pair" does? What kind of magic previously unknown to mankind is that?
I love cable sound threads 🙂
If it was usable up in the GHz range, it's quite obviously some kind of quality coaxial cable - which we all know is totally useless as IC's..... no?
WAAY to cheap - even for high quality coax...
Must be the price. 😀 Pity though, I like silver cable. Apart from that they sounded quite good.

Well then I must be a moron but moving my head by 1" only move the soundstage a little bit, no change in the sound of the instruments, perhaps you should try it. 😉
On the other hand, a system may sound "cold" or "sterile" due to distortion characteristics.🙂
John
..........in their effort not to sound "warm".......
If someone is EQing for a warm sound they are distorting the original signal. Its really simple stuff.
All recordings are distorted compared to live.EQing your system in your room is the only way to listen to music that irritates you less.Who likes to hear a thin bright sound because the X sound engineer decided to record it like this?Is this what accuracy is all about?What if it was you who made that recording?Would it still be accurate compared to X's recording?
Is this the second time you'd made the erroneous assumption that I haven't measured my speakers? You really do seem to enjoy the propagation of misinformation. Once again you attempt to obfuscate, I know you don't have anything better to say, but I get the feeling you didn't hear the other portion of the proverb.
Ok, let's assume that I didn't just tell you twice that I've already measured the speakers. Let's pretend I didn't measure this pair, or that I've never owned speakers before this pair, or that I've never measured other peoples speakers or that I build and calibrate sound rooms for money. Now that we've set that all aside, even if none of that was true it wouldn't change the fact that anything audible is measurable given the proper equipment and understanding. Are you going to once again point out something completely unrelated to the subject at hand only to sneak in a non-sequitur in the hopes that somehow what I had for breakfast makes you less wrong?
If I may,John has asked you if you have measured for your cabinets colorations,distortions,call it anyway you want.Not your speaker's responses etc.....

In your room,listening position and speakers an inch difference could be disastrous.In my room,listening position and speakers 5 inches difference could not be a big problem,and they are not.As Andre said there is a little shifting of the soundstage,but nothing serious in fr

As I understand it you define "warm" as being coloured sound
I think that "definition" of "warm" is incorrect, and old
In my world the real true "Warm" sound is only achieved by high resolution, and a reproduced sound that is true to the original

Odd choice of cable for audio. 50 ohm (high capacitance stuff, might be a problem if you were using a tube preamp).More strange, this cable were used with test equipment for measurements up to several Ghz.
Likely was made with SMA, N, or possibly TNC connectors, since test equipment doesn't use RCA phono plugs or XLRs which would have pretty bad VSWR at several GHz. Most microwave test gear use SMAs or N types, as can bee seen in any Agilent or Rohde -Schwarz catalog.
So you guys had some type N-to-RCA phono adaptors made to attach these cables to the system? How did you connect RF microwave cables to audio gear?
Or are we talking IEC power cords? Those are used on RF test equipment.
I used to keep an SMA-to-AC power cord adaptor hanging on a nail by my desk "for effect" and used to get some pretty odd stares from other RF engineers.
Nope. Nor do I hear their character change with wire, either.
Depends on how close the wire is to my ear. :]
