Hello, Im a Tidal Contriva owner and not an active (writing) Audiogonner, but Im reading this forum for over a year now. English is not my mother language but can read and write Fortran and Pascal very well. Im a music lover over 40 years and have experience with audio apparatus as well.
I did also play the bedroom guitar (acoustic and electric) and love this instrument and know how is must sound. Here are my findings about the remarkable Tidal Contriva (Not the SE or Diacera):
The speaker has very, very little or no sound made by itself and is one of the very few, which can make a very realistic view of the performers in depth, width and height and get the dynamics right.
This was always a compromise, or there was space and depth and little dynamics or there was great dynamics but no relation to space and depth.
Most speakers with great dynamics do emphasize the first attack and do a bad job with the signal after this first shot. Smash in your face and no real space and depth.
Phase shifts in the signal are responsible for the Place in Space and the brain does the calculations with this information and not so much with the relative loudness of the signal. When this is not correct, the brain is working overtime to correct and compensate this (mis) -information. Speakers which are more right in time and space (filters with respect to phase) are less real life dynamic, again the brain in uncomfortable with the smoother dynamics and interpreted this as less realistic.
For me this was resulting in buying the Avalon Opus (4-way) (after IMF, B&W, Thiel and more) and feed them with one of the fastest amplifier in the world: the Atma-Sphere MA1. For years this was very involving for me, but then I was beginning to miss the dynamics such as produced by Wilson Audio. Changing cables or amplifiers didnt add any speed.
I do have two separate (both shielded and balanced) 230 VAC circuits with old fashioned circuit breakers (silver, copper and/or gold fuses) and a dedicated to audio only ground pin, 28 meters (92 feet) in the Dutch clay, and all this doesnt make the Opus any faster. Yes there is more gestalt and the total picture is more life but not live. You can hear all the differences and they worked out very well and makes listening more pleasant. I have done almost anything to the acoustics which is possible in a normal medium sized family living room and end up with 2 large tube traps behind the curtains, carpets on the floor and walls, a air suspended audio rack and the use of Zilplex (a better and less costly alternative for the acoustic system resonators). And to make a long story a little shorter: I found all this wanted audio aspects in a speaker from the unknown TIDAL company.
I contacted Jörn for just over a year ago and this did result in buying the Contriva in 2011. Jörn and his right-hand Felix personally delivered and installed the Contrivas in my living room. The Contrivas are revealing, fast and spacious and oh so naturally sounding. No sound of there own, real dynamics (at low and high volumes). No ceramic sound, but it differs of course from the less stiffer paper cones. The result of using Accuton (Thiel & Partner) is Imo that you can hear more micro information while the cone is doing the macro dynamics and that (with a well engineered filter network) the phase relationship is not corrupted. This means that you can hear a cymbal in space like in the real world: explosive and with all that beautiful tingle, tangle and shimmering and staying on the same position. Not so perfect (engineered) speakers cant do that and throws the sound (for a short while) in front of the speakers, moving back to the original position after the pulse (attack) is gone and giving the space related micro information again, not disturbed by the large scaled dynamics.
My brain is not working in overload anymore, at least a lot less then before the Tidal Contrivas.
Sometimes it just appears if the music is going a little bit slower then before, I mean that a second is lasting a fraction longer then before. Its more relaxing, involving and not tracking attention to itself or it should be the perfect piano lacquer and the beautiful lines of the mighty Contriva.
