The BAT mono's sound pretty good (improves on the single-it's not just more power).
This is a tough choice.
The vk55 uses the 6sn7 on the input which gives some beauty in the midband. The 75SE likley has more control and extension on the extremes and I suspect better,wider, deeper image-but a little cooler tonally.
Wish I could help more, you won't make a mistake either way!
