Tube preamp recommendations for Pass X260.8 monos

Hi all, I just got a new-to-me pair of Pass Labs X260.8 monoblocks. I’m interested in shopping around for a tube preamp to pair with them, and am curious of your general thoughts. I’m not sure of a budget just yet, but I know I’ll want something commensurate in build quality, performance, and yes… beauty. I’m pretty sure I can guess a few of your responses, but I’d love to see if something I haven’t considered shows up. Thanks in advance!
