Two preamps in PC applications


I'm sure this has been asked before but I am but a lowly padawan in this world. I am building a PC and I feel the sound quality is sub par so I am looking at a Claro Halo by HT Omega https://www.htomega.com/claro-halo.html. But I also would like the warmth of tube driven sound especially in good headphones. Now, would something like say a Nonsound tube headphone preamp. Plausible?
