Yes, the HD650 plays very very well with the WA2.

Sorry to hear, did you try Mullard CV2492, in my ears it is a perfect combination that is very musical
Yup - tried them. Also got some Svetlanas (Black Plate 6N13S) that was recommended in this or a similar thread as "as warm as it got". I like them - but they didn't make my T1's unbright enough (however - I've got some sensitive ears)
subscribed, better late... Happy WA2 owner since 2009:-) Use them with HD650, but just got a T1. Both are great with the WA2. For closed cans I use DT770/600 and DX1000. Though DX1000 isn't that high impedance (70 ohm) it a very good pairing with the WA2, infact I don't bother to listen to DX1000 on other amps than WA2...
I am a WA2 owner since 9 this morning. Sold my WA6 a couple of weeks ago. Some report that "right out of the box" the sound is fantastic but for me the first hour or so was a bit rough. Now, however, this amp is "ripening up" beautifully. I think that this is going to be a long and satisfying love affair!
What tubes are you using?
Mine shipped with JJ EZ81 (I was surprised that they were not some type of EZ80), JAN Phillips 6080WC, and Counterpoint 6DJ8. I will spend time with the stock tubes before I roll.
I would look at upgrading the power tubes first (most affect on sound) then the driver tubes and finally the rectifier tubes. FWIW, my favourite WA2 tube setup was:
Power tubes:
Tung-sol 5998 (not the 5998A tube which is only average) but good ones are hard to come by. Failing that, the Tung-sol or Sylvania 7236 tubes are quite good too. The GEC 6AS7 are highly rated power tubes too.
Driver tubes:
Mullard CV2492s (but they tend to be microphonic) and Genalex Gold Lion E88CCs
Rectifier tubes:
Mullard or Telefunken EZ80s.
Have fun tube rolling. But the amp really came alive when I swapped out the stock 6080 tubes.
Thanks, I look forward to the journey.

black looks really good with the tubes all lit up in low light.
its just like a black car,
looks phenominal when clean.
but you're gonna want to dust it often.
search hi and low for a pair of Tung Sol 5998s.
if a web site offers a phone number call them. ask for used that test well or NOS. you're gonna pay out the butt for NOS though. Make sure the place has a return policy.
i scored a PAIR of them used but still testing very good for 40$ last month.
but make sure they have a good return policy.
i've read of a few people getting those tubes and them already being microphonic or sounding bad
Been a WA2 owner for some time now. Happy to see a thread dedicated to it.
