Same goes for Jazz/Blues really. Again, you just have to hear them for yourself. The clarity, transparency, imaging and soundstaging I promise you is worth the tradeoff in bass for the Sr1a. Now, if you're contemplating them as a replacement of what you have or as an only headphone then I'd totally understand maybe looking elsewhere.
I wouldn't be surprised at all that's the case, especially if talking meet/demo/short window situations. Even if not, still wouldn't be too surprised, as they actually do a lot of the same things really well and preference is pretty important. There are only three things I prefer about the 009: 1) it has the best vocals and overall midrange I've ever heard (ATL3000 deserves a mention here, and also the Susvara is close); 2) It has better bass and is a better all rounder; and 3) I do still prefer the traditional headphone style in comparison to the Sr1a. Now on number 1, obviously subjective, but the Sr1a is the closest I've heard to the 009 in this regard. Number 2 and 3 applies to the TC and Susvara as well. I love the Raal's presentation but sometimes it makes me miss the more traditional headphone enclosure of the others. And definitely the bass is better with them as well. It absolutely could not be my only headphone.
That said, the Raal simply does things the others cannot. It is more open, more transparent and clear than the other 3. It EASILY has the greatest wow factor of the 3, followed by the TC and then the 009. All of that said, there's a lot of overlap with the 009 and the Sr1a. I don't see the point in owning both, I just don't have a need to sell so I'll enjoy them both for now.
My honest recommendation would probably be to go the route of the Raal + other planars. With stax you need a beefy amp and tbvh, I'm a bit unimpressed with the other headphone stat offerings in comparison. I'm not sure I'd spin up a stax rig from scratch unless I just had the money/time to. To put it more clearly, if I could only have one rig, it wouldn't be a stax rig. But having both a dynamic and stat rig is amazing.
