OP:
If budget is a strong consideration, I'd suggest:
Buy a Dell 27" 4k, but pick "the next model down" from the UltraSharp.
It will probably have a "regular" IPS panel (instead of IPS black, which the UltraSharp has). But that's OK -- the panels otherwise are very close in quality.
Something like this:
Shop the Dell Plus 27 inch 4K Monitor with AMD FreeSync Premium, 120Hz refresh rate, dual 5W speakers, and 4-star eye comfort.

Or this:
Shop the Dell 27 inch 4K USB-C Monitor with AMD FreeSync Premium, 120Hz refresh rate, dual 5W speakers, and 4-star eye comfort.

A 4k panel will be "what you need", if you're working with DAW apps.
Plenty of "room" to see more of the timeline, have additional widows, etc.
I'd also recommend using the app "Better Display" with ANY monitor.
It offers some features in "free" mode, more features if you register it.
I registered it "on sale" for about $15. Glad I did.
