I agree. The Sophia Princess can be fun, has an interesting presentation, and looks incredible, but is not close to being worth the money.
The Brimar is a great rectifier as joseph said, most of us have a few.
That said, at this point I am running a copper cap for my rectifier, and I will never go back to any other rectifier. Its price/performance is unbeatable. It clearly bests the Brimar, and also my U52, which I ran for a long time before. It gives as full of extension as I think any rectifier can, is tonally accurate, and dynamic. It is not recommended by Woo, but I've yet to see anyone have a problem with one. The U52 does have interesting qualities next to it, namely a very liquid midrange, but I'm starting to think that it's not actually liquid, just a little emphasized. And people who have compared the copper caps to the Takatsuki say that they are at least comparable. I would hope the Tak would beat it.
Anyways that's all I have for rectification. Don't buy a U52 like I did, either get the Brimar, a copper cap, or just go all the way to WE, Taks, or the new Elrogs (if they have their stuff sorted, haven't payed attention).
For power/driver tubes, you'll want to get a 6DE7 --> 6F8G adapter, so you can use 6F8G, 6C8G, and other tubes. They seem to be the sonic equivalent of 6SN7 in many cases, and offer some other tubes not available in 6SN7. More than that, 6F8G is cheaper than 6SN7. On ebay right now, you can pick up 4 National Union 6F8G for 110. It would be hard to beat that sound at that price. I use NU for my tubes. I also have Tung Sol 6F8G, which are also incredible. Probably slightly better than the NU, but who knows. Either are head and shoulders above anything else.
And that's what I have to say about power/driver tubes. Get the adapter, pick up NU or TS 6F8G or 6C8G or equivalent.
edit: Just a quick edit that all of this is in reference to the WA6. I'm using it with the Mimby, and Grado PS500. Also have the HD650, but everytime I pull them out, I don't see a reason to keep listening to them. Mostly I keep them for the long cord, sometimes it lets the woman and I listen at the same time.
