Warm and accurate bookshelves that can handle volume

This is a lot of tremendous advice. Will hit the road, and never thought of going to an audio show. The you tubers say it is hard to listen properly at an audi9 show but might as well find out. From a near vacuum to being surrounded by audiophiles. 

Show conditions often not ideal, heard Magico S5 mk2 often sound great, but only ok at last AXPONA.  But you’ll likely hear something that “you” favor subjectively and will give much more examples /information than you currently have.  Helps if you have a list of brand/model speakers you’d like to demo.  If the brand is demoing a different speaker, then you can discuss w the sales rep the technical and sonically similarities and differences between their models - there’s often a “house” sound due to consistent components and/or design voicing.

Plus one for Sonus Faber for “accurate”, “warm” and high volume capable.

ATCs are certainly “accurate” and have a very high performance envelope in terms of loudness, but I doubt anyone would characterize them as “warm”.  I have listened extensively to the latest generation SCM19 and they sound terrific with competent electronics, but the term “warm” never came to mind.

attending an audio show would be a fun experience, and at least you could get a good look at the cabinets in person (if that is important) and get some inkling of the sound signature, if a bit uneven due to compromised and uneven listening environments.

A couple of different directions.  Dynaudio Heritage Special that probably prefers solid state electronics.  Gershman studio II a warmer speaker for those that don't like grating treble.
