Excellent. Good to know. Here's a rough sketch of the intuitions driving my last question. Suppose -- and this seems to be the case -- that the general consensus is that the WA6-SE>WA6. And this registers as, in part, a difference in their specs (e.g. frequency response). Now, suppose again -- and I'm not sure if this is the case -- that the WA7>WA6. Then, it would stand to reason (by analogy) that the WA7tp>WA6-SE. Essentially, what I want to know is -- and what, perhaps, people don't yet know -- how the WA6-SE and the WA7tp stack against each other. I currently own the plain ol' WA6 with the (Sophia Princess and 6GL7 upgrades) and am looking to transition to the next level.
