Complete Revamp (Including Sound)

[LZ Holy Narwhal]

I'm renovating my setup. I'm building myself a new desk with a mixture of IKEA parts, and I have these pretty good Logitech speakers with subwoofer (Which I don't know the name of, they're pretty old but they're fine) but I am planning to get new speakers. I just bought myself the Fulla 2 from Schiit, and the Sennheiser HD 650s. I'm wondering what speakers would be great to get. Max budget $300 would be great, and I was looking at the Creative SoundBlaster X Katana soundbar, and the Kanto YU2 speakers. But I'm torn. I have a white setup, and I want to have good speakers, and the Katana seems like a good choice to sate my RGB hunger, but at the same time I am open to suggestions for other studio monitors + subwoofer for the new desk. Any suggestions?
