In search for speakers of "natural" sound

Hi 
i have owned many high end speakers 
from Avalon,Genesis,Proac 
etc.
i recently saw and read some comments on this website about a 
speaker by the name of Usher Mini
Dancer ll with Diamond tweeters 
i read a lot of great reviews and decided to buy a pair and to my surprise probably the best pair I have owned so far.
very natural and life like.
Give it a try.

Consider KEF Blade II loudspeakers with VAC amplification (at any price level).......remarkably natural sound and soundstage! .....near totally removed from the loudspeakers. Some great suggestions above as well. If you prefer a solid state amplifier, Clayton Audio matched with a VAC mk5 Preamplifier is a very close second with the Blade II.  Enjoy!

If if you are in the UK please get in touch for a demo.

What is your system?

Tough question to answer when you omit the primary style of music you listen to, info on your romm size and treatments if any and your other components and of course your budget. All of this info is required to be able to properly recommend a pair of speakers, As mentioned above your present speakers are from a highly respected company known for producing a natural sound. For this reason I suspect your room and / or other components are in need of examination prior to the speakers. This is assuming you are looking to improve your systems sound. If you are just exploring other peoples idea of what they think a natural sounding speaker is in a general context then this info isn't required.

For naturalness you need a very dynamic and unforgiving speaker. Preferably a pro studio monitor, active or passive. Great suggestions would be ATC, Westlake, Quested, PSI, Unity the Boulder, Barefoot, dual centric Tannoy and many more. Westlake is a "new" favourite of mine. 

Note - with these your bad recordings will sound bad and the good will sound good sometimes fantastic. They will not all sound mediocre as with most HIFI home speakers. Your Harbeth should be ok although being a home speaker. I found it a bit uninspiring. Harbeth also have studio versions. Don't know if they are different. 

If you with natural sound means concert sound, then visit a live venue. I don't want that sound in my home because it's very seldom enjoyable. You don't go to a concet for the sound. Maybe Roger Waters...

Not sure about the open baffle suggestions. Can't think of a speaker technology that interacts more with the room. But would like to try in the future.

Also, as someone already pointed out, try to find the good recordings and skip the bad. Discover new artists that really try to also present a fine sound. There are lots of them. Also the same artist may hav a big spread between good and bad recordings. Sometimes on the same cd. Listening to John Fogerty when writing this and he is a good example. Tidal is great for this.

Just my ideas and Good luck!
