In search for speakers of "natural" sound

Hi everyone,
Thank you all for your valuable input. I am using Harbeth 30.1 with pow/pre Quad 909+Quad 99. The source is DAC Yulong D18.

I believe that Harbeth can sound better but I would need to spend a lot for amp and source to fully exploit its potentials. This is part of the reason why I want to try other names , which are less demanding but still keep up to the same quality.

I always like Quad ESL, however, I heard it's only for one listener because of its narrow sweet spot. Also, as reviewed,  its size and room space demand and that its fragile diaphragms can be more easily damaged than the traditional speakers, which discouraged me somehow. :)

I don't think I am into warm sound. I just need neutral and natural one. 

I am in Orange, CA.

How do you hope to achieve natural sound with a digital source ? 
It's futile. There is nothing wrong with your speakers, that are considered to be among most natural sounding.

Digital has a natural sound. It’s the sound of paper mache.

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.
Thanks

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)
