In search for speakers of "natural" sound

I am using a pair of Harbeth speakers. However, I am not satisfied with the 'naturalness' of the sound (it could be that I am so demanding). I am looking for a pair of speakers that can produce the more natural and organic sound than Harbeth if there is any.

I know that it depends on the amp, cables, and other variables. However, let's assume that with the appropriate gears, which speakers do you think can produce the "most natural sound"? By "natural", I mean the sound that we hear directly from musical instruments, from the singer without going through any amplification.

There is a user mentioning that speakers from the past used that 'natural sound' as a reference when designed speakers. In contrast, the sound today (even the hi-end one) is to "hi-fi". He guessed it could be less people have chance to listen to live / acoustic music than before.  

Is it right?

Thank you for your experience and recommendation!

P.S: I know that my questions are silly and dumb, please bear with me.

Yes I am a dealer and have sold, heard all the speakers mentioned in  this post. 
 What I have learned over the years is that it is important to obtain a speaker that does not interact with the room as most box speakers inherently do - due to the laws of physics.
 Yes electrostatic speakers that are dipole in nature will have less interaction with the room however I have found that the transformer which is used to charge the panel does interplay on top of the actual signal that is going to be reproduced as music.This is not ideal when you are looking for the proverbial straight wire with gain or ultimate in transparency. 
 Speakers on the other hand that contain crossovers have a whole host of other problems including the loss of transparency phase issues etc. in comparison to speakers that do not possess or crossover at all.
 After approximately 30 years of my quest for the ultimate speaker that produces the highest level of transparency which does not contain  any crossover components on the main panel  and is mated to open baffle servodriven subwoofers with an onboard computer  inside the servo plate amp -this quest has ended with the 
GT Audio Works planar magnetic speakers
 Along with the SI  Open baffle servodriven sub woofers.
 The technology in these speakers is just to comprehensive to list on this blog and I would encourage you to contact either Steve at Sound insight or Greg Takesh over at GT audio works for a comprehensive and detailed description of this technology.
 Most importantly let your ears be the judge we encourage auditions please contact  Steve at sound insight- his information can be found at the Facebook page by googling sound insight high-end audio.
Sound Insight

1. Quad ESL 57 or 63, but don't expect any deep bass and they are finicky

2. Harbeth M30.1 or 40.1, but the big ones are pretty expensive (basically BBC monitors brought into the 21st century)

3, Tannoy Red or Gold 15" (SWEET in large enclosures, SUCK in small enclosures, best with tubes)
The only speaker that can come even close to the sound of a "natural" instrument is going to be a speaker that plays back electric guitar or other instrument that uses such speaker for its amplication and tonality. As soon as ANY instrument or voice hits the diaphragm of a microphone, compression function is invoked and this is the fundamental reason no speaker (another compression function) will ever sound like a natural instrument or voice. It is why we can tell if the music from way over there is live or recorded playback. Loss of timbre, frequency and dynamics can never trick our ears into believing otherwise. The key is to find speakers and other components that do the least amount of damage. And, having said that, there's nothing we can do about the recording and mastering brought to bear on the original performance. We must always suspend our disbelief if we want to enjoy recorded music played back on an audio system.
harbeth 7es3 > mc452 > C52

great combo imo. It really was the solid state amp that made the difference.
