All right. Luckily I can still have those
Oh Sh*t moments.
So about walls of sound ...
I reported a few times more (maybe 2) that the presentation of the sound (music) can be such that it is impossible to determine the depth. By sort of accident I now have that again, and this is one to stay.
So Joachim, this time I have it so explicit that I now (and finally) liked to play the Seagull again.
(and yes, when I take a step back like from that sort of 3D sound I tend not to listen to such thing as the Seagull any more because I will be disappointed)
I can't call this a wall of sound, but maybe this is not really the case in your situation as well, Joachim. But still, I (we ?) can't tell. A wall of sound comes across as "massive" to me, and possibly still from some sort of plane. But I have been thinking about the possible causes of this, and it looks comfortable to think we both experience the same thing.
So now maybe as a sort of
for others :
At the very first notes from what I played yesterday (say for now with my new "mod") was that sound was so way outside of the speakers - I never experienced it like that. All Q sound so to speak. Think like me being at 10 meters from the speakers, while sound from left and right sprung from around 4 meters distance in front of the speakers and then from all from the sides (walls). Looks like impossible, but still so.
Of course, when you envision this, it already becomes more easy to see how no real plane of the sound can be detected, no matter how hard you try. Sound is from that 4 meters distance from the speakers to begin with, while at the same time the real source is still the speakers.
But don't apply too much math to this, because even at this 10 meters distance it was hard to tell where the sound came from, when you're, say, twist yourself more than 90 degrees from normal listening position *and* at some side (so not in the middle at all) and then you wouldn't know whether sound was from the left, right, front or back. Only twisting yourself to another angle would detect where the speakers really are.
Crazy.
What I did to achieve this is actually illegal. That is, officially not right but in a damn difficult area of electronics with by now my question to what degree schoolbooks are correct. For you it would be more acceptable because it is actually about our BNC cable again and how "you" keep on thinking that friggling around with this will always lead to
some result for the better. And as we have seen by now, this is so (and quite easy to achieve), but to what degree it is perfect is something else and ... what I just did should not be perfect.
And I changed from perfect to almost illegal.
Still assumed that Joachim is able to encourage for the same wild difference (in the Wall of Sound department), then we must think about what this tin layer or nickel or gold plated etc. etc. really does. So I actually see more and more explicits about this (about the BNC to RCA adapter) and you can bet that I a. believe in the wild differences but b. they should be utilized once we understand. And a "hey it is gold plated" makes no sense to me for merits. Nothing does of course (maybe later) but that these things matter - yes.
So, finally, what is it what I did ?
I moved the "by law" output impedance resistor from as close as possible to the gain stage, to 18cm away from it. In theoretical effect we now deal with that 18cm of cable capacitance and it could inluence the output stage in bad manner. And maybe it does, so now we're up to "and do we care ?".
If you next see me saying "and don't you dare to make a next one even 1mm shorter or longer" then you can see how at least I see this as an infinite tweaking possibility. I mean, *if* this would be about reflections now
occurring in that piece of cable, then they are for the better (as perceived by me) and they will for 100% sure depend on the (exact) length. Remember my *if* because again I can't tell (requires special analysers). And "if not" then the length is not (or hardly) important either but then it becomes hard to tell what makes this crazy change.
But think again about some silver/gold/nickel whatever connector/adapter and it is easy to see *that* such changes are possible anyway.
You know, when you see Joachim write such things, you may easily think "oh well - he sure will have managed to change something for the better". But now there's number two (me) - possibly in quadruple - and you just won't be able to imagine what a super
crazy change actually "nothing" makes.
So I had this before and back then I came up with the Seagull example because of it. However, when I later "softened" the sound, the effect went away and I wasn't very sad because the net result was better (say less sharp, less "too dynamic").
This now (too dynamic) is all out of the way, but again it (3D) can work. You can also hear what makes it happen and this is the very special highs. As usual this is not easy to explain, but think they got more white as in where cymbals tend to go physically smaller. More resolution in it (and when too much the cymbals all end up in 10cm cymbals). A large part of this is done by the Blaxius cable but now this resolution itself becomes more profound or something. You just "see" how in fact all (the more squary) is positioned somewhere and when this smears ever so little it meshes up more in the the middle.
When I had this working previously (early Seagull times) it also worked, but there the whole spectrum received the "dynamics" and it wasn't the nicest in the end.
Right. Although you did not see it really, this should be the final result of my attempts to create something with the Blaxius cable that you can apply yourself. Or maybe not, but then go to an electronics shop with someone being able to hold a soldering iron with very small tip and the harder part of it can be done there in a minute or three (seriously) and you give the guy 10$. The remaining parts can be done by anyone who owns a soldering iron and uses it now and then, but if you're in that shop anyway ... That part will take possibly 30 minutes by that guy. You yourself may need maybe 75 minutes, including taking some breath in advance.
This is still only the NOS1a part and whether the amplifier part also needs to be done depends a bit on whether you are super satisfied without it and can phycologically overcome the BNC to RCA connector, which thus *also* can matter a lot. In any event all material will be provided for those who order(red) the cable, so you can go all directions.
How to go from BNC to XLR I did not work out yet.
