In hifi audio,we tend to want to the least microphonic tubes we can get because that translates into lower background noise,better detail,and better dynamics because excessive noise or microphonics in a tube will be amplified as signal thru an amplifier and will rob a lot of the good specs of the amp or preamp.
That said,military and industrial tubes tend to have less microphonics many times because they are built a bit more rugged or they at least test better than the standard issue tubes most likely.
Does this mean the 6678 will sound better? All you can do is try it and see how you like it.The green Syl 6U8s are very good as well and that's why I say try it.
