I could have kept the WA6 and been very happy for many many years. The WA6 is, perhaps, the sweet spot in the Woo line. The WA6 is not extremely spendy and there are many inexpensive tube rolling options. I did some rolling with my WA6 without throwing crazy money at tubes. At $13 each, from Antique Electronic Supply, I felt that the Valve Art 274b was a pretty good rectifier, that same supplier offers many, very reasonably priced, power tube options. I never really ABd the WA6 with the WA2. With capacitor upgrades and tube upgrades my WA2 cost 3 times my WA6. I think that the WA2 is better resolving, has greater grip on the music and has a tube magic that is really wonderful to listen to for hours on end. I have done a fair amount of rolling with my WA2. As I type and listen at this moment my amp is running the stock rectifiers, Matsushita 7dj8 driver tubes and Tung Sol 7236 power tubes. I think that you’ll enjoy any choice that you make from the Woo line.
