I've compared a ARC Ref 3 to a BAT VK-51SE and a BAT VK-32SE, though not the VK-52SE. In my system, I'd rank them in this order:
ARC Ref 3
BAT VK-51SE
BAT VK-32SE
ARC and BAT are just different. The ARC was more revealing and transparent, while the BAT was more dynamic and powerful. Note that while trying all of these preamps I was using a modified BAT VK-75SE amp. I felt the ARC/BAT combo gave me a taste of both worlds, the speed and resolution of the ARC mixed with the power and dynamics of the BAT. YMMV.
Cheers,
John
