Luca; beautiful pictures....your room and system are elegant......a great place to listen.
i have heard the Savoy's and they are, like you say, something beyond the Andra's.....very refined yet effortless and dynamic.....always listenable.
i have heard the Viola gear at shows but never really 'investigated' it. i do think very highly of the Kuzma.
from your questions to me i assume you are intending some sort of room project; will that be in this main listening room or in another?
