Yes would like to hear your impressions on that (if you get your hands on a Stax tranny).
Back to my question, do you mean the Audeze vegan pads?
Since reading these points I've been ABing the SR-009 with the HE-6 only amp playing some jazz on Spotify. The edge that the SR-009 is really not as great as the price makes it seem. There is simply more bite with the HE-6 (visceral?) and that seems preferable with the sax. I think I might indeed prefer the HE-6 to SR-009 on some music but hey, no harm owning both :P
The DP-777 is a really good match with the HE-6. It used to be the case that I couldn't bear using the Sylvania 6SN7W chrome tops on my amp, but with the DP-777 which eliminates all the digital harshness, I prefer that to the warmer Tungsol driver tubes that I used to love.
Yes, the Audeze Vegan pads. They make as dramatic if not a bigger difference than the grill mod. The felt mod is the cherry on top that binds both mods together.
I don't listen to classical at all so cans like HD800 or 009 don't have as much of an advantage (if any for the HD800) so that bite the HE-6 does wonders for what I listen to. HE-6 definitely does electric guitar better than any headphone. Does very well with 80's hits and Cantopop too!
