Pretty much any preamp including tube pre-amps should work fine with that amp. So it really comes down to what you need in a pre-amp. You probably want a newer model with latest greatest usb input. Otherwise a separate dac with analog out.
integrated amps are also a very good choice these days but features vary widely as they do with pre-amps. Take a look at the Bel Canto c5i wihich is a true digital integrated amp. It’s a wonderful device packed with well executed modern technology and top notch. sound. I’ve had mine for a few years now. I decided to try the latest and greatest technology before giving more tubes a try. Glad I did. Don’t miss the tubes at all.
