I would like to spin what @drbond said.
You have lots of opportunities to improve the sound incrementally and then a big bump when you get to the end of the next upgrade cycle.
‘’It looks like all your components are very roughly of the same caliber… great.
So, it appears you like Sonus Faber sound… I do to (see my systems). I am on my third set, upgrading from old used to new higher level. Each provided a great bump up in performance. I would start there.
So, the question would be how big a jump? I upgrade to a new level about every seven years and take about a year or two to make the transition.
You want to put in no less than 2x the cost in each component… less is likely to be disappointing.
For the first upgrade, I would recommend speakers…. Wait ~ six months… then DAC. Then wait ~ six months upgrade integrated (preamp and amp only… no other stuff). Then streamer.
Unless, you have some compelling reason to add analog I would not… this just dilutes your investment in the core stuff.
Even if you cannot have a dedicated audio room… keep the 2-channel audio separate from the home theater (get a sound bar for the TV). Otherwise your 2-channel is going to be tremendously compromised… or you’ll need to spend 3x on the whole thing or more and still have a compromised 2-channel system..
Get the best speakers you can. Olympica are fantastic… I had a pair for nearly 10 years.
Think roughly about 35% on speakers, 35% on integrated, 15% DAC, and 15% on streamer. Worry about cables and cords after you have landed on your ideal components.
Recommended brands:
Speakers: Sonus Faber
Integrated: used, Audio Research or Pass
Streamer: Aurender used N100… new N150
DAC: Schiit - Yggdrasil
If you are able to pull off the above upgrades over whatever time frame… you are going to have an system performing at levels above what you have now. Each step should provide great satisfaction. Get to know each new piece as you get them and save for the next.
Then you can get into interconnects, cables and subwoofers.
