Hello, everyone.
I transitioned from (five figures worth of) headphones to loudspeakers this year.
Started out with JBL LSR305 active studio monitors and am now using Klipsch RP-250F passive floorstanding speakers and a Behringer KM750 power amp.
I'm in a humble bedroom and haven't bothered with EQ or room treatments (I'll get to that eventually), yet the sound I'm getting is vastly more realistic than any headphone I've heard. (And I've owned/heard a good percentage of the high-end ones. Read through my profile for details.)
In fact, in my experience, there isn't even a single category that headphones can compare in. (Except perhaps bass extension...which doesn't really matter since my speakers already give me all the bass in nearly all recordings even without a subwoofer.) Yes, headphones make certain details more apparent since the drivers are right next to your ears, but louder detail is not more detail in my book. I have yet to hear a single detail on a headphone that I don't also hear on the speakers, and in the latter case it's represented in the subtler, more natural way it should be rather than artificially emphasized. On the other hand, I'm hearing countless details on the speakers that I have never heard before on headphones, and every aspect of sound is better; sometimes shockingly so. (Even STAX, my favorite headphones, sound like cheap toys in comparison, though to be fair I have not owned high-end STAX.)
The only Schiit product I use at the moment is the SYS passive preamp / switcher, but I had a handful of others in the past.
As far as speakers go, I used the Fulla 2 as a DAC and/or preamp at first, then upgraded to the Modi Multibit. (And various non-Schiit DACs and DAC/amps. The best so far was the Chord 2Qute.) I also used a Wyrd at one point, but it only made a slight improvement.
The SYS sounds substantially more accurate than using (at least some) active electronics (such as the Fulla 2 and iFi micro iDSD) as preamps. (A notable exception is Chord DAC/amps, which are also digital preamps and don't color the sound when adjusting the volume. Their amplification is in the DAC's analog output stage and is cleaner than even the line outs of conventional DACs. They can directly drive sensitive passive speakers too!) This makes sense since the SYS (say that out loud...lol) doesn't have any electronics and is basically not altering the signal aside from attenuating it. A slight downside is the soft scratching sound it can occasionally make due to the cheap potentiometer. I don't mind since I rarely notice it.
Here's a photo I took when I owned the 2Qute, Modi Multibit, and Fulla 2 at the same time:

I actually downgraded to a $30 DAC (Behringer UCA202 audio interface) but am getting better sound than ever before (when I used high-end DACs) since I upgraded the speakers.
I'm mildly curious about the benefits a higher-end power amp could bring to the table. For example, what would the Vidar do that my current power amp can't? (The one I have has more power, so quality is the issue.) If someone can explain this in an objective technical sense, it would be appreciated. (My endgame is one of the upcoming Chord digital power amps, but those are expensive.)
Anyway, I'm going to focus on speaker upgrades before anything else. (My ultimate goal is to achieve the highest fidelity possible, but these things take time...)
Since some of you may be interested in this company, here are the speakers I'd like to get in the future. Owners and reviewers are going crazy over them, saying they outperform speakers many times the price, and the designer claims they're the most accurate and acoustically advanced speakers ever made.
