Where does a VK-30 with NOS tubes fit in with this comparison. From my experience, I will not purchase a tube pre that uses only 1 type of tube. VK-30 allows tube rolling. May be able to acieve top end air with NOS and 6pak oil caps. Just a thought as I'm interested in BAT myself but don't care for silver/black chasis or only choice of 6H30 for tubes.
