Help looking for dynamic warm romantic sound with detail

Try a Vinnie Rossi LIO integrated OR his upcoming L2i Signature integrated (or his separates of course, if you can swing it). Both DHT. To pair with whatever speakers you decide on. Fitting paring parameters followed of course.
The point there is you can roll a wide variety of very musical Direct Heated Triode tubes until you find the fine tuned sound you’re after. 

Also switch out to try the Duelund Wire w/ the new Duelund RCA plugs for interconnects and speaker cables, too. The Duelunds are cheap enough to have on hand to try with what you may demo.

And as mentioned, room treatments to mellow the room and help further bring out freq balance and detail. 

How your treating the wall power is also a factor to rid system of brightness.

I've been in your shoes before. And it’s all about fine tuning once you think you’ve found the contenders. It takes a whole room and system approach to get there that does not end up with something to dark and closed-in. 

Clean the power good > room treatments in the basic spots > choose speakers > choose amp > wire > tune room treatments. 

Once these steps are taken you may even notice that your ears do not ‘need’ as much warmth and romantics as thought to be comfortable. 

The sound you are looking for can be had with a Luxman 590 AX II driving Wilson Sabrinas.

I can agree with the Luxman. I had one for a bit paired with the beautiful, incredibly real and dynamic sounding Daedalus speakers and it was warm in all the right ways. That system could be turned up loud with no brightness and sound sooo so good. Even with a mid-level DAC.
