You generally won't be able to tell how much modern DAC sucks until you got a really high end accurate system. That means super high damping (making integrating the amp into the speaker mandatory), plus you'll need balanced power (to reduce noise by 10-20db, a miracle btw), you'll also need low jitter input, but that still leaves a huge weak spot the analog XLR cable, so you'll need a very good one there too.
So if your current DAC sounds fine, don't upgrade your gears :)
Sure, and you generally won't be able to tell how much modern homes suck until you move into the Palace at Versailles. That means sleeping in Napoleon's bedroom, sitting in with the Assemblee National for French constitutional reviews, and getting dressed in the Hall of Mirrors. Of course the weak spot may be your wardrobe, so you'll need to drop $400K on some custom-tailored suits at Cifonelli in Paris. So if your current home works just fine, don't start phoning realtors in France.
Or, said a different way, modern DACs don't suck for 99.999999999% of the lifeforms on this planet, not necessarily including llamas and pigmy marmosets.
