I'll offer a slightly different take. I am decidedly not an audiophile. I like my music a lot, and I like it to sound good, but having listened to a bunch of DAC/amp combos, I find the bulk of them functionally interchangeable - I personally cannot tell a difference between them. Of the ones I can distinguish, I can't say I felt any strong preference for one vs. another; they were just slightly different.
I have a Schitt Modi, with an AudioEngine amp, passive speakers and their subwoofer on my desktop machine. It sounds great to me. I'm sure it would also sound great with this combo device, and also if I dropped mid-4 figures on the DAC and amp. I have headphones, but never use them and probably should sell them, but those sound great on the amp, too. Before this setup, I had an SMSL Q5, and it sounded just peachy, too. I keep looking at these ads/drops, thinking I'll see something magic, but... not so much.
So my recommendation - if your ears are like mine, there's very little point in dropping a ton of money on kit like this - at some, relatively low-cost point, it will make no difference at all. Put the bulk of the money you intend to spend on the speakers that sounds good to you, find an amp that can drive them properly, and go with a cheap DAC. .Maybe spend a bit more for the next step up, if you like the way it looks better, or get a DAC/amp combo if you want fewer metal boxes in your life.
If your ears are less tin than mine, or you just like blowing money on expensive electronics, then I just wasted two minutes of your time, and you should ignore this.
 Great speakers would, in fact, make a huge difference.
 Switched for reasons involving a toddler, a stick, and said toddler's father buying me off afterwards.
 or phones, if you lean that way.
 but also, watch yard sales/Craigslist/acquaintances who are moving - you can find great speakers for very cheap.
