What is the best thing for me to upgrade next?


Hi all, slowly working on upgrading my system and could use some advice on where to put my money next!

I only have 1 line level audio source - a streamer and that’s probably how things will stay. I’m not interested in amassing a collection of physical media. All of my music is stored lossless on my NAS.

Here’s where my audio chain started:

Phase 0:
[Source: Sonos Connect] > [DAC: None] > [Amp: Bose Lifestyle] > [Speakers: Bose Acoustimass 3]

I recently replaced my speakers. And I’m now using an amp that I had in storage that I intend to ultimately replace.

Phase 1: (now) [Source: Sonos Connect] > [DAC: None] > [Amp: Harmon Kardon PA2000] > [Speakers: B&W 805D3]

Phase 2: (next)???

So where do you think I’ll get the most bang for my buck once I recuperate from Phase 1 and am ready to buy the next things?

Do I save up to replace my amp next? Thinking something like a McIntosh MC302

Do I put a DAC between my streamer and amp? Thinking something like a Topping D90 or something from Matrix Audio (Element X / X-Sabre Pro, etc.)

Or replace the streamer? Not sure what yet, looking at Aurender, Node 2i, Sonos Port, etc.

What are you thoughts on where I should go next once I recover from the speaker purchase?

That’s something that I’m still wrestling with - I think an integrated is definitely the easiest way. I was looking at something like a MA7900 which comes with a DA1 dac and leaves the door open to a DA2 upgrade in the future.

Ofcourse, going integrated means more compromise, and I kind of liked the idea of going separate to leave open the option of adding a tube pre-amp in the future possibly. 
My speakers are rated for 50-150W. Does 200W leave enough margin or should I be aiming closer to 300W?
Well, given where you're coming from in phase 1, I think a super integrated amp that includes a dac and streamer would be a nice next step, just to keep things as simple as possible.  Your speakers a def the nicest thing that you have right now.

As far as options for those all-in-ones, you could look at NAD, PS Audio, Naim, marantz, Hegel, to name just a few.  It's a burgeoning segment so there will surely be more to come soon.

If you don't value the simplicity of an all-in-one, you could perhaps get better sound by getting separate integrated amp and dac/streamer, and of course there are hundreds of combinations at that point.
Surprised, no suggestions?

in my uneducated view - I’m thinking that the heavy hitters would probably be DAC or amp, then streamer. 
DAC is probably the least expensive thing on the list which means faster ROI, but - hypothetically speaking - I’m not sure if a better amp would have a bigger impact on the sound (albeit at a higher cost). 
Decisions, decisions!
Hi, I figured that by offering examples of what I'm looking at, that that would have helped to determine a rough range. To be more explicit given my examples:

Amp: MC302 is about 3.5-4k used, I think

DAC: D90 is around $800, X-Sabre about $2k new

Streamer: $500 (new) -$2.5k (used) depending on which ones

Although, I'm more interested in the abstract - in that general range - what am I better off getting next? DAC, amp, or streamer?
Eisen,
if you seek informed responses you need to state your budget and what you hope to accomplish. I'm not being critical but your post is not specific enough.
