David741Totally different type of product. The sprout is used with passive speakers, while the 11.28 is for use with active speakers. The headphone amp is more powerful in the NFB 11 (3W @ 32 ohm I think?).

David741the audio-gd 11.28 is a dac/headamp with a pre out, so you wouldn't connect speakers to it other than active monitors or active speakers. As a headphone dac/amp it is excellent, probably one of the best in class at price. if you wanted to use the audio-gd 11.28 as a preamp with passive speakers, you would need another speaker amp too.
this is an integrated amp with a low power headamp built in, so it can power passive speakers and switch inputs, but the headamp output looks to be pretty low power, some of the core specs arent listed at all, and it doesnt look like anything special on that end compared to say a schiit, grace, or bottlehead, etc. this would be more for speaker folks.

jersey_boySorry for my ignorance, but what is the difference between active and passive speakers? Because i see people in videos connect speakers to them, like in zeus videos.

elad_eActive speakers are powered and thus don't require an amplifier. Passive ones do.

yeldSo the nfb can drive passive speakers, But can't manage active speakers with inside amp?

elad_eother way around. nfb has a preamp output, it can drive active speakers, by outputting a line level signal. passive speakers need a speaker level (amplified) signal.
For most scenarios, active speakers would be speakers with a built in amplifier. typically these are most commonly monitor bookshelf speakers such as say audioengine A5 or jbl LSR305 speakers, rokit's etc. active speakers would typically have RCA inputs etc, passives would have binding posts or terminals for speaker wire, spades, bananas, etc, to connect to an amplifier. you can think of the nfb11 as sort of a preamp, with a headphone amp in it but not a speaker amp in it.
the particular unit, the NFB11 is a headphone amp with a built in dac, it can drive headphoners, or output to powered speakers or a separate amplifier for speakers. a comparable product would be say, the audeze deckard, or the massdrop CTH+sdac.
the sprout/2 is what you would call an integrated amp. it has a dac, phono preamp, and a speaker amp, and a headphone amp all in one unit, but the emphasis is on the speaker amp, not the headphone amp on a unit like this, the headphone amp is pretty low power.
