Didn’t catch your budget but when I was looking for a tube preamp to warm up my room I narrowed it down to Aric Audio - two options at $950 and $2700, and Maple Tree Audio at ~$1,000 or a little more depending on your options. I decided on the lesser expensive Aric preamp but his point-to-point wiring design has allowed even a novice like me to take it to a completely different level by putting in much better capacitors and tubes. After a good burn-in period after the upgrades, I put it up against a friend’s ARC LS26 in my system and with the exception of a tad better bass, the modded Unlimited preamp sounded as good if not even with a little better air around the vocals and the instruments. YMMV depending on your system. Just something to consider if esthetics (and brand) are not a priority.
Edited to add that I bought mine used for much less and the total cost for upgrading the tubes and the capacitors - Audyn Coppers, all per direct recommendations from Aric, were less than $150.
