Any idea which headphones I’d like?

@toddcowles I too have sold off all my two channel, loudspeaker stuff and have allocated all of funds towards my headphone system.
That system now consists of a Metrum Pavane L3 DAC, Luxman p750u headphone amp and HiFiman Arya ’phones.

I chose the Arya because I like the planar magnetic sound. Some people claim the Arya is bright but I’ve never experienced that. To me, they have a velvety smoothness in the midrange that I look for in a good headphone.
The bass has tremendous weight but it’s not the lightning fast, tight, accurate and very detailed bass of the 3 Focals I had here, ( Elear, Clear and Stellia).
Those headphones, especially the Stellia, did many things amazingly well. All three were undoubtedly the most dynamic and hard-hitting headphones I’ve ever had the pleasure of listening to. Sometimes I really, really like that. I almost felt it in my gut.

So anyway, it’s difficult for me to think what headphone would work best for you when you describe your loudspeakers. It would be easier for me to recommend a headphone with my very limited knowledge in this subject, to ask what it is exactly you want from your headphone.

If you like amazing speed and detail, lightning fast Dynamics, and hard-hitting sound, I would recommend something like the Focals. All of those characteristics get better the further up the line you go. However their  sound stage is slightly too small for me.

If you prefer a very buttery, velvety smoothness in midrange, nicely detailed highs exceptional base response with a wider soundstage, then I would go planar magnetic.
Something like HiFi man or Audeze.

What’s your budget?

@devilboy thanks for the input.  My budget was in the $10 - $13k range.   I’m a little paralyzed over which direction to head and really want to listen to some of these setups.  Hence, I’m plopping my money in my eTrade account and waiting to attend a CanJam, or possibly RMAF.  I didn’t want to, thought I’d move forward easily with a purchase.  But, as many pointed out, you just really need to hear them as there’s not a comparison.  It’s a different listening environment, elements, space…everything is different about the hearing process vs a loudspeaker.  So, rather than forge ahead, I’m waiting.  I’ll likely wait until the 2022 CanJam in Chicago, or the RMAF…global pandemic aside.  

Good decision to wait until you can put some on your head and ears. The comfort factor is a priority, if they aren’t comfortable it won’t matter how they sound.
With your budget I’d buy an amp, a pair of open back and a pair of closed back ‘phones. And maybe some upgraded cables.

@toddcowles understood.
Another option is The Cable Company. You can audition headphones and headphone amplifiers at home for 5% of the retail price for a period of two weeks. I believe whatever you spend on "renting" that equipment will get put into a pot and applied toward your final purchase regardless of what it was you auditioned. You can try 3 headphones and decide to apply those 5% fees towards an amplifier, for example.
Check with them.

That's a nice, healthy budget.

I too am moving away from 2 channel and into a good headphone setup.

I already have the Focal Elegias for a closed back, and I'm waiting on a backordered Schiit Lyr 3.  I plan on also adding a Bifrost 2 and a pair of Meze Empyreans around bonus time.  Hopefully that will do it for me.

Good luck.
