$100K system build - % breakdown of spend

Thanks for the replies. A little color:

The current room is multi-use and has more glass than ideal, but all in all could be a lot worse. Irregular shape, about 15x20’, with 18’ ceilings. Setup takes a little dialing in with an opening on one side and behind the sweet spot, but I’m very happy where I am now. Likely a new house in the plans in 18 mos. or so, but for now am planning on similar listening space. Truth be told, my listening time skews slightly toward streaming - maybe 60/40.

Current items I’d put on the ‘keeper’ list:

Technics 1210GAE, AT Art9XI cart., Modwright 9.0x phono

A pair of Rel s812’s

On the upgrade list:

Sonus Faber Sonetto III’s

Hegel 390

Bluesound Node 2i

Lower/mid range AQ cables and interconnects

I think the Hegel and the Sonetto’s make a great match, especially with the Rel’s. I think longer term, I’d like to move a notch or two (just a touch) toward warmer, maybe with some ARC gear. I’ll be upgrading step by step, toward a longer-term hold system maybe over the course or a couple years. I may have a tough time moving away from Sonus Faber - they would be less than what I listed above, but I’ve heard the Serafino (not with ARC) and could be very happy there I think. There’s obviously nothing magic about the $100K figure, other than determining proportions roughly at that level.

I suppose the benefit of subs depends on how low your speakers go, at any price. Granted, the Sonetto’s only go to 42 Hz, but I think the Rel’s (19 Hz) would be additive to many very nice speakers. They make an enormous difference in my room at high and low spl’s. Perhaps I have more to learn here. 

@jrw1971 - I’m definitely open to used gear. Like I said, the amounts I listed are mostly just to establish a relevant ‘neighborhood’ for comparison between/across components. Thanks for the offer re: add’l thoughts on ARC - may take you up on sending a PM. 
 

@barts - no hurry on my end. It may well be that I hold off on speakers and perhaps amps until I have some clarity on what the new space might look like. I feel fortunate in that my wife supports my efforts here, and am happy to make the tradeoff maintaining her interest at the expense of a dedicated room away from the rest of the house. New house will probably be a new build, so will have some thinking to do with combined living/audio space in mind. 
 

Perhaps nearer term I focus on dac/streamer additions. I totally appreciate the idea/recommendation that I try to hear as many different systems as possible in the meantime. Am hoping to hit axpona, for one. 

Thanks @petaluman and all others. Fair point about the room. The room now (and in the future) is not a TV room. I think windows will be the main obstacle. Similar to my room now, I’m probably destined for a main floor room, mostly dedicated to hifi, with some plants, shelves, more seating than just the sweet spot, etc. I’ll have to think about windows/treaments some, I think. Received a copy of Jim Smith’s Get Better Sound over the holidays - haven’t started yet but perhaps I’ll get some ideas from there. 
 

I also appreciate the comment re: power conditioning.
