3-Dimensional Soundstage


I have appreciated a quite nice separation of instruments in my system's soundstage.  I have read many times about people experiencing depth in their music and have never appreciated this.  I was talking to an audiophile friend this week about it and he brought up the fact that recorded music is a mix of tracks and how could there be any natural depth in this?  If there was a live recording then yes, it is understandable, but from all studio music that is engineered and mixed, where would we get depth?  Are the engineers incorporating delays to create depth?

With many classical recordings, on my system it sounds as if much of the orchestra is located behind/beyond the wall behind the speakers.  Studio recordings can be engineered in a number of different ways.  All I know is that I have some pop/rock CDs where, for instance, it definitely sounds as if the bass guitar or the drums are well behind the lead singer.

@dhite71 - If you think of how we "percieve space" from sound e.g. live music...

  • think about the various artists are spaced on the stage
  • as the sound of each instument reaches our ears, our brains interpret two slightly different sounds
    • one ear hears a slightly louder sound
      • which provides us with the ability to
        • assess the location of the artist in the ’left to right’ plane
      • when both ears hear a slightly louder sound we can
        • assess the location of the artist/instrument (front to back) in relation to other artists/insrtuments
  • however those sounds are also slightly out of phase
    • it is the phase that provides that final piece of the puzzle
    • the various phase differences between what the left and right ears actually allows the brain to build a more accurate representation of the live performance in relation to "our location" within the venue
      • so if we are located to the side we build a totally diffeent image to that of a person having a more central location
    • Also, when we listen to a recodring, the image may or may not be confined to the boundaries of our listening room.
      • i.e. provided we have good system in a perfect listening environment

The sound engineers in the recording studio can manupulate EVERY aspect of a recording

  • each instrument and artist are recorded on their own track
  • the signals can be manipulated, such that the "sounds" of each track can be "placed" with great precision in any part of the resulting image in left/right and front/back planes
  • and using the subtle differences between what our left and right ears will eventualy hear, by adjusting volume and phase differences between the left and right channels - they can build a pretty convincing "image"
  • these days, even "venue acoustics" i.e. those little echoes and reverberations generated by music being played in a venue, can be emulated, to achieve a more relaistic reproduction.

When playing back a recording, better systems will take the recorded signals in the left and right channels and reproduce them with an amazing degree of accuracy, such that, it convices our brain that we are in the venue where the recording took place OR in the "vitual venue" as created by the very best sound engineers.

The really great thing about today’s electronics is that you do not have to have the very best components to get a reasonably realistic sounding image.

  • but you do need to have pretty darn good cables!
  • because cables actually play a significant role in conveying those incredibly detailed signals while maintaining the ever so subtle variances in phase between left and right channels
  • thus allowing the components to build that amazing image

Every cable in a system will impact sound quality in some way.and it isn’t until you start using excellent cables that you will be able to hear very noticeable improvements in imaging.

Those mega expensive systems you hear at audio shows and at those high end audio stores all have excellent cables.

Hope that helps - Steve

 

Great post....

I will only add a remark about cables...

Relatively good but not too much costly cables will do... Why?

Because most of all acoustical cues cannot be rendered audible in a badly treeated and controlled room ...

Then cables are important to gain the better information possible but there exist aminimal threshold of information quality without paying many thousand dollars for cables  then it is irrational and useless to pay more for cable  than to  room acoustic...

Dont throw too much money on cables, more on acoustic...

My cables are basic good relatively low cost one...Not cheap one at all, but low cost...I begin to listen ALL imaging, soundstaging, timbre naturalness etc AFTER acoustic treatment and control...A huge difference, i repeat : HUGE....

Too much money on cables and nothing to acoustic is a lost of money...

@mahgister - thanks for your comments.

I do agree to your second point - however - in my years of designing and building cables I have found that the benefits of well designed cables can be heard even if the acoustice environment is lacking some acoustic treatment.

I started building cables just because I believed that audiophiles should not have to pay excessive amounts for good cable performance.

During the development process I came to realize there are a few things that many great cables designs share

  1. cable geometry - i.e the proximity/spacing of each wire within the cables
  2. the type of metal used in the wire e.g. OFC, UP-OCC copper, Silver
  3. The type of insulation used - governed by Dielectric Constant
  4. the qualtiy of the connector

Unfortunately, incorporating the best of these attributes in a cable does increase the price of a cable, but today there are some very good cables available for what I believe is a reasonable price.

But it turns out that cables are no different from any other component

  • excellent components can command some very high prices
  • but you will never get to fully appreciate just how good they are if your cables are poorly designed
  • just as - you will never get to fully appreciate just how good your system is - if the aocustics of the listening space is lacking treatment

There is fine line between brilliance and insanity - especially in this hobby 🤪

I never contested that "differences" between cables cannot be heard if the room acoustic is not treated and well controlled, the difference can be heard in ANY room with ani system...

I tested difdfrent cables before my scoustic journey and i always hear a "difference" ...

But a diffrence between cables is not  the  specific improvement of  all acoustical cues of the system room...

What is an acoustical cue?

Timbre, dynamic., imaging, soundstage, LEV/ASW ratio, Bass clarity, all that is specifically and hugely differentiated and improved by acoustic treatment and acoustic mechanical control of the room... Each one of these cue is DIFFERENTIATED and IMPROVED not only lightly changed...

Cables cannot have either the impact of vibration mechanical control nor the same impact than the control over the decreasing of electrical noise floor of the house/room/system and not on the same level in my experience...

Cables make an impact but a small one compared to the three embeddings controls : mechanical,electrical and acoustical... For most people even a 1000 bucks cable is too much and way better invested in these other areas i just described...

Anyway you are not alone on this boat, most people cannot fathom or imagine it because they never experienced this the HUGE improvement created by the three embeddings controls...Especially acoustic....

I know i have read many audio threads and the same ignorance is evirywhere... I woud have never know it if i had not go through it by chance and by reading in acoustic...

Most people boast about gear brand name and cables brand name...

Why no system at any price cannot change my mind about this?

My 500 bucks system is not far behind ANY system at any price why?

Embeddings controls of the system/room...But my claim is unbelieveable anyway for those who dont have lived through the same...

I even cannot listen to any of my 8 headphones, they are infeirior on all acoustic count to this 500 bucks system...I begin my journey with headphones improvement...I will never listen an headphone again ... Do you imagine?
