We are dealer of Stillpoints. Mann they can do things what you never can create by buying an amp, speaker or source of 100.000 dollar.
A better timing ( what stillpoints also do) create much more precision. Instruments and voices become more apparent. The space is getting bigger but the black level is getting higher as well.
You need to understand what each part in your set does, before you can create stage depth and width.
We are not even talking about stage height, this is a league on it's own. It even influences the sound when 2 voices come toghter. Beside the blending of voices you still can hear were they are at the recording.
When people of Auro3D/Dolby Atmos talk about 3D and height, I always spoil there part. And I will explain in details why we are listenign to 2D sound. After my explanation they are always quit. This is the level of audio these days. Customers get stuppid information of these people.
I give you the reason why the Monitor Audio ribbon tweeter outperforms dome tweeters.
First of all voices and instruments are sharper focussed and they are more physical apparent.
The can create easier depth and width compared to a dome tweeter.
The most fun part is that it is able to project voices and instruments even in front of the speaker. This is combined with projecting the music beside the speakers.
When you listen to speakers with dome tweeters, the voices and instruments stay more at the front line of the speakers.
I give an example: Miles Davis; Kind of Blue DSD by the Lumin S1: It brings you back to 1959.
You are there in the space of the recording. You hear the differences in heights of the recording. They were one of the first to use microphones this way.
The piano on the left side sounds more like real bur also gets a shape. The drums is fully free at the left side. It plays beside and in front of the speaker. And you hear the heights of the high hats in the space.
The ribbon tweeter can create much more space than a ribbon tweeter can. Beside this the focus is sharper. Not even for free I would want a speaker with a dome tweeter.
Audio is using the properties to the max. The ribbon tweeter gives me much more space and diversity to use.
