I agree with the assessments made in this thread. That said, I prefer the Sovtek to the EH, for their clarity, extension and transparency.
My BAT Rex uses 4 Sovtek and 4 Reflektor NOS 6H30DR in the power module, and a pair of the Sovtek 6H30 in the main module. I've tried just about every combination, including all NOS 6H30DR, and what I listed above gives the most dynamic, natural, clear, and extended sound.
