In search for speakers of "natural" sound

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

This just goes to show that talk with someone enough, and some commonality can be found 99% of the time. 

To anyone who posts with a specific model or brand of loudspeaker to the OP, you have exhibited your own foolishness. There are only conceptual answers to be given validly to the OP, not specific. His choice of source has already self-limited his experience. 

I don't care which Harbeth he has or whether he has Harbeths at all. He could have 30 year old Realistic by Radio Shack (rip) speakers for all I care. Get a better source, preferably analogue, and position your speakers properly, make sure your room is not causing problems, and you will be on the right course. 

The problem with this Board (well, among lots of others) is that it does not allow posting of photos. I would love to see good photos of the OP's listening room. I bet his Harbeths are up against the front wall with a flat screen in between or close. You can lead a horse to water, but you can't fix a wife. That's a WAF joke. 

Huy; again, I am not in your room. Everything matters. The flatscreen in between the speakers has to go. It is not about being on or off, it is about that highly reflective surface where you need a sound absorbing surface.  If it can’t go, you must find a way to temporarily cover it up with sound absorbing material. Look up GIK Acoustics. Your Harbeths coming out into the room will decrease gross bass but once you get out of the room nodes (look this up), your bass will sound tight and more realistic (less bloated). Tiny changes make a huge difference, most times. The only proper way to do this is to lay down painters tape into grids so that you can keep your changes consistent. Let me say it again because it can not be said enough, everything matters. You must nullify first reflection points at the side walls and ceiling. You must have complimentary cabling. You must have a clean power supply. You must have the right seating position. Pick up Jim Smith’s book "Get Better Sound". Jim has a hundred or more tips and some will apply and some will not. If you take the time to try his tips, most of which are labor intensive but not expensive, you will find the sound you are missing. Please trust me-it is not your speakers and simply looking for some magic speaker to obtain your desired "natural sound" is, uh, not natural.
