Warm romantic & detailed

Consider auditioning speakers in the Legacy Audio line.

I second the votes for Sonus Faber speakers as "warm," of course with the appropriate amp etc.

in my two past experiences i felt sonus fabers were smooth and warm, at the expense of transient accuracy and dynamicism

I'm going to throw in a bit of a curveball here.

I use a Devialet Expert Pro with CI board. They've always had bass and treble adjustment but lately they have introduced what they call "Sweet Room". It's meant to be for room correction but it's basically a 9 band equaliser.
Someone came up with the idea of using it as a way to put a 'warm' curve in instead of room correction. I gave it a go and it works a treat. You keep the detail that the Devialet's are known for but you can make it sound as warm (or cold if you wish) as you want.

It just gives you that versatility that you need to make any speaker sound great. On top of that there's SAM, which makes just about any speaker sound better than they are.

Worth a thought.

I also had a pair of ushers that managed to walk that line. The A21 is impressive in its build and its got power, but it is a little thick and speakers with hot tweeters will expose it. If you like the focal sound why not try the Kanta 2? Same excellent mids but a little warmer balance.
