Nigel, baka pretty much answered the taming thing. The WA6SE is said to have more highs than the WA2, and the 650s have some kinda rolled off highs, so it sounds like the WA6SE would be the best of the two for the 650s if you wanted to fix that, which is taming them. If you like that characteristic, the WA2 would be the best out of the two to complement it.
650s seem to lack detail and the great soundstage everyone talks about in the 650 Appreciation Thread, and I think it's my amp because I have a PS Audio DLIII DAC. The WA6SE is said to havre the better soundstage and detail of the two, so that would work out well for me.
Plus overall, if the WA2 is the more warm and tubey sound and the WA6SE is the clearer, solid state like cousin, I'd rather have the 6SE because I feel the 650s already accomplish the warm tubey type sound and I don't want to increase it, but decrease it a bit to try having the best of both worlds, clarity and detail with a tubey sound, like baka said the WA6SE did vs. the WA2. I had a Darkvoice 337 and I didn't like the "tube sound", like it sounded less detailed and had a worse soundstage (it had two volume knobs so I had to just center the soundstage with both knobs to sound right, and this obviously wasn't how the music was supposed to sound, but I didn't know what it did sound like, so I had to set my own soundstage, which was not so good. That's why I sold it) than my Audio-gd Compass, which is about half the price. Even more so it had rolled off highs, just like the 650s, and it was just too much for me. I want to try tube amps again because of my ignorance of tube rolling. It was probably just my tubes I was using that made it so, not the simple fact that I was using tubes.
Thanks for the replies!

With regards the HD650's if you want to liven them up a bit,tighten the bass and make then a bit brighter then go with the Woo6se.
If you are perfectly happy with the way they sound and want more of the same go with the Woo2.
In what way do the HD650's need 'taming'?

I have said the dynamics of the WA6SE was a bit less dynamic than the WA2 and the beta22. Everything (the loudest and softest parts of a song or music) with the WA6SE, to me, seemed to sound closer to the same volume than on the other two amps. This is offset by the great soundstaging I felt the WA6SE has. This is not to say that I felt they weren't dynamic, but compared to the other two excellent amps, it sounded a tad less. All said, I did prefer the solid state sound of the WA6SE to the warm and fuzzy sound of the WA2.
