This looks like a great system, Robin!
I am not familiar with the VOBA Acoustic line of loudspeakers. Can you elaborate a bit on the design and sound characteristics of the VOBA speakers?
I see that you have a set of Reference 3A Veena loudspeakers in addition to the VOBA V.A.C.T. reference monitors that are featured in your pictures and your thread title.
What role do the Reference 3A floorstanders play in your systems, and how do they compare with the VOBA V.A.C.T. monitors?
