Hello! Thanks for reading, I really appreciate it!
I haven’t used the Kraken Tournament Edition….but I have used the Kraken V2 it’s based on, and the Razer Nari, which uses the same pads and the same THX Spatial Audio.
It is indeed a very good virtual surround sound system. One of my favorites. And Razer’s pads are equal to HyperX’s in terms of comfort. Their memory foam is just as good, and their cooling gel really does make a difference for the first 15 minutes or so you’re wearing them. You can read my Nari review here, if you’d like.
The only complaint I could lob at the Krakens is the lack of a removable cable. They also have a signature that’s “tuned for gaming,” meaning there’s a little more oomph in the midbass and in the footsteps region of the treble than some folks might want for music.
Honestly though, all the models you’ve picked are headsets I really personally enjoyed. I’d be happy with any of them as my main headset. I know that’s not helpful when you’re trying to find the “best,” but the differences are all going to come down to your personal tastes. If I were in your place, I’d pick the one that appealed to you personally. If you like bass, the Razer, HyperX, and Logitech models will all sound better than the Arctis…but other than that they’re all very competitive with each other.
And you’re right, your sound card is more than enough to drive them. If the Logitech G Pro is available in your area, the leatherette pads and improved microphone make it a good competitor to the Alpha is well, so I’d check that one out too.
