Concerning the ideas of warmer, fuller, colder, thinner in the Synchron Series, it has to be highlighted that you have a mixer to shape your tone. I've found that the raw tone is very flat and neutral, and that it depends on the mix where it will lean.
For example, I would say that the Mains are very trasparent, with not much body. Adding the Center mic makes them fuller. The Surround/Outriggers add air and width, dimension, space, but no body.
The Middle and Close mics is where body appears. Sometimes there is a second Close mic, pointing to the second row, to the second chair, to the bell, and it is often a ribbon mic. This adds a lot of warmth and body to the tone.
In SUDS the mid/close combo has been empowered with a full section. I would expect this to add body, as I actually hear in the demos. Paradoxically, I feel and suspect that the Stage A-only recording is less full-bodied than in SSP.
VSL adds algorithmic reverb to the closer mics, and this adds a cold, glassy icing to the sound. It's a way to blend the drier close mics with the room mics, but I find that they also remove some raw beauty from the natural sound.
Just my impressions. In the end, what I want to say is that Synchron requires experimenting with the mics and the mixer.
