Speakers that can reveal orchestral instruments' positions

IF your photo moniker is your setup, try moving the cone floor standers away ( and shorting them w jumpers ) and moving audio rack to the side. Big changes but worth doing IMO
jim smiths excellent book on getting better sound also advised.
best to you

Yes most good speakers set up well can do it to some extent if it is in the recording to start with but omnidirectional speakers set up well are suited for it best due to the more lifelike sound dispersion pattern with omnis.

The best Example I have ever heard was with Mbl 111 speakers at old now defunct United Home Audio showroom in Annapolis Junction MD several years back. The showroom design and system setup was very optimized for the Omni mbls with a good 10’ or more of tapered and treated room space behind the speakers.

Using a high quality master reel to reel tape as a source you could identify player locations in that area from front to back and side to side exactly as if they were set up in that space behind the speakers.  Nothing else I have ever heard comes close. 

Same setup later at a local show: not so much.

My Ohm Walsh pseudo-Omni speakers at home do a good job with this but not nearly to the extent of that mbl setup which was the best I have ever heard at that by a very wide margin. Ohm Walsh are designed to allow placement fairly close to walls which fits most people’s needs better.

Yes, it depends much more on the quality of the recording than on the capabilities of the speaker (though that obviously too is a factor).  I have an extensive collection of classical CDs, and through the same system the soundstaging sounds anything from excellent to non-existent.

<<<I feel far less from my Tyler Linbrook signiture's>>> please explain.
Tyler, now defunct, used the famous SEAS Excel drivers in that system, same as my SEAS Thor MTM's
I only listen to all styles of classical and have no issues at all with SEAS voicing CM.
Not sure what you are talking about?
I can say, only i update my preamp and Defy 7, I will hear more sound stage in CM. 
= the potential is there in the SEAS, you just have to upgrade all your components with correct mods. Such as Mundorf caps.
The M caps allow sonics to sparkle.
There are quite a few techs who claim new caps are snakeoil, anda  complete total absolute waste of  money.
I just had to prove them all wrong. 
and I did.
Prove that group witha faulty judgement,,,sure they'll say,,,<< lets look at the specs on a  screen,,,ahhh exactly same specs as the Real caps>>> fact is , a  lab can only tell numbers,,,the nuances ofa  superior cap, can not be measured on a  screen.
Bottom line, you can get a  broader sonic sound stage  on a  speaker with new caps in all your components.
