Would love to see some pics of your setup if you have any! I have to imagine that Vincent is a nice match for the dyns.
Here you have a few pics. I'm a long term Vincent owner and the dyns are a nice match for this amplifier.
The couch is of course not the sweet spot it is mostly used for reading books and relaxing. The sweet spot is a chair, in the middle of the living room, that can be switched around for either best listning position for music or to watch the telly in the opposite corner of the living room.
A Bluesound Node X streamer is hidden behind the amplifier and is controlled via the BluOS app from the iPad. There are no needs to have easy access to any of the units, so the location below the couch is convenient, even it is not common practice
