I'm hearing great results by including my Woo WA2 as the pre to my Stax 353X. The tubes are Tung Sol 5998 Amperex 6922 gold pins and Mullard EZ80. Only downside is I have to use the balance correction on the Stax for about an hour. The WA2 setup has warmed the sound very much and no sounds awesome. Rock is up there with my 1266 TC and Solitaire P. Rock won't be dethroning those two planars yet but it could. I'm to guess there are two different drivers in each cup? I modified the fit with a looser seal at the bottom to increase low frequencies to be get some boom. Rock sounds more alive without sounding bright. I'll hear some dryness then some liquid depending on recording and both ways sound great. They never sound boring so dynamics and musicality is there. I don't think that the Stax Mafia could ever except anything else but what's their name and that just bias, because 1266 TC kills that brand, it is named the best headphone ever and the Rock is got the balls. SR009s sounded great but was way too bright not in a harsh way and did someone put a high pass filter on it because it has no bass. The SR007 mk2 had more too it as natural but still lost in bass as it couldn't keep up with my planars. My only bias and I'll admit it that the 1266 and Solitaire are planar and that's been my favorite tech, but the more I listen to Rock the more it sucks me in. So if I never put these above the other two it's just my bias or not.
If anyone is curious the two amps cost me $1600 the tubes where $1300 If I didn't sell the my BHSE I'd have a comparison to give the WA2 doesn't have pre anymore it's been re-engineered to sound better with the added room. Though you can make a great sounding amp section by getting a tube amp with pre connected to an energizer.
