Recommendation for tube preamp

Hi, all. Initially I was going to ask, which would you rather own – Audio Research LS2B or (BAT) VK-3i? But realized I’m sure there are plenty of other tube options. As you can gather, I’m looking at around $2000 range. It will be driving ML 27.5 amp, which is partly why I’m looking specifically at balanced options. But I guess there’s no harm in using unbalanced>balanced cables? I listen mostly to jazz on vinyl, so I enjoy the details but not to clinical levels where it’s dry. I want warmth. Fine with a phono stage included, but not needed.

Appreciate any insight. Thanks.
