Advice needed for upgrade path


I need some advice on how to proceed with a HP system upgrade.  It's for a second home, a condo, where a good 2-channel speaker system just isn't practical.  In 5 years or so my wife and I will downsize and the condo HP system will then be it for critical listening.  I currently have a set of HD650s.  For the interim I could simply buy a used Naim Uniti Atom HE and enjoy that with the Senn's until the dreaded downsizing.  Or I could start to put together a HP system for critical listening.  How to start, though?  Maybe get the Naim and a couple of mid-priced used cans from TMR.  Take my time listening to a few different brands like Audeze, ZMF and Meze.  I've visited the HP room at Axpona the last two years but just did not find that setting helpful.  And then there are amps, days and streamers.  My head hurts at the options.  Suggestions? Thanks.

OK, in my main system I have Stirling Ls3/6 speakers, SVS micro 3000 subs, the Bacch4Mac spacial system and ORC dsp.  Streamer is a Node with LPS and English Electric Ethernet switch.  Amp/dac is Peachtree Gan1 modded by Ric Schultz.  I really like the BBC sound, focusing on a rich mid-range.  I abhor too much detail (cannot listen to Borreson speakers).  and I don't appreciate bass slam.  I'd much rather have low volume subtlety and precision.  Music is eclectic: female vocals, Argentine Tango, Van Morrison, acoustic blues, some classic rock.  I expect that eventually I will port the Bacch system to the headphone setup, but not initially.  

@calieng You are right: I owe it to myself to try tube amps.  I have no experience with them.  There's a WA22 for $1200 on USAudiomart.  Now for DAC and streamer.

@larsman what tube amps do you recommend?

Thanks.

If you want to try stuff out, you might check out headphones.com, they have 365 day return policy. 

@treepmeyer - I would go along with what some of the other responders posted. The ones that I have are small, hand-built ones with very long waiting periods, but there are loads of others. Headphones.com is a good place to look, as are Moon Audio, Upscale Audio, The Music Room; you could find others with a google or AI search. After checking out the websites, you might want to call some of these places and see what they would recommend for your tastes and budget.... Many of these places will allow you to audition gear for 30 days or whatever and if you don't like it, you can send it back for another or a refund.
