Transepts - Anybody upgrade from a Jays CDT2 MK2 to a Jays CDT2 MK3?

I’m looking hard at doing the upgrade.
I would be especially interested in any improvement in vocals, since I feel the rendering of vocals in groups of 3 or more, (background vocals or group vocals/choirs), is the most difficult task a playback system has to handle. I would also be interested in other areas of improvement, as well.

Somebody must have made the switch from MK2 to MK3.
Not interested in other recommendations - thank you.

Tim
