I will be curious about your comparison. I'll be looking for 4 6H30s soon. DRs are too rich for me, so I hope you decide EH is just as good, or even exaggerate a little and say they are better, wink wink...
Can you also describe the difference between the EH and Sovtek if you have some of those? They are from same factory, so I wonder how much difference there really is between those two cheapest New Sensor brands. Just gold pins, or do they look different inside? Thanks, and have fun!!
