I have no experience with tubes but have been contemplating like you. Seems like the following are well regarded in your range based on what I have read:
Audiomat Arpege (new/used)
VTL IT-85 (used)
Unison Unico (hybrid)(new)
Manley Stingray (new/used)
Conrad Johnson CAV-50 (new/used)
Cary and Jolida too!
