Hey, new user.

I already have an average audio interface that I use for really only recording vocals on both PC and Mac (Presonus 24c). I was looking into stepping up my interface and was wondering if there were any recommendations for some of the best ones on the more pricey side. I’ve been heavily researching and looking at the Apollo twin/rack series and RME uf/cx series to compare but I’m really unsure if it would be worth if I’m just recording vocals mostly and occasionally an instrument. Is it better to invest in the more professional interface with more i/o, converters, preamp, etc? Is RME better than Apollo in this case? Thanks for any and all the help!
