What does "not good enough" mean? Does it suddenly become unlistenable?
I've only heard the SR-207 using my laptop's internal DAC, which, as I mentioned, sounded the same to me as a Schiit Modi 2.
Then allow me to rephrase:
In my opinion, I did not like the SRS-2170 with the FiiO E17, I think I paid $150 for the E17 a few years ago.
In my opinion, I did like the SRS-2170 with the $400 Beresford Caiman II DAC.
In my opinion, the SRS-2170 reveals the shortcomings of cheap DACs, OTOH, it doesn't require a crazy expensive DAC.
I've never tried it driven by my laptop's internal DAC.
YMMV.
