This morning found some time to compare the ECC31, the National Union 6SN7GT and the Sylvania 6SN7W. Of course, neither of the 6SN7s match the ECC31 on bass, but otherwise, they are very similar. I find the Sylvania to be the most similar to the ECC31 in the mids and highs, while the NU is just a bit darker.
On a side note, I modded my HD700 last night and I am very pleased. The edge is gone and the treble is much smoother.
Thank you for confirming this gibosi! I'm glad others hear this as well and it's not just me being unable to hear more of a difference. I like both the NU 6SN7GT Black Glass and CNU 6SN7 Grey Glass, they sound similar to me.
Which mod did you perform on your HD700? I'm still contemplating doing something similar to my T1s however, I must admit I have some reservations operating on 1000 dollar headphones..
