Two options that are very interesting:
Chord Ultima 3s - these are much warmer than prior Chord amps which were notoriously bright. There switching power supply and auxiliary rail allow them to handle shockingly low impedances. Preamp here will matter. You are going to want a warm preamp to pair with it. Not sure what you are using now. The price on these at the moment is amazing and I can’t mention it publicly but it is on one pair and is a first come, first serve situation. You can add in a brilliant, warm preamp to go with these and be below budget.
AVM Ovation MA 8.3 - 1100w of power into 8 ohms, a proprietary tube input stage that doesn’t need replacement and a warmth that will make a tube lover happy. I have heard a pair of these driving Magicos without issue and currently have a pair on order for a customer with Kef’s. The list is $34,900 but these easily could be your end game amps.
