Our community has rated this post as helpful. If you agree, why not thank

Fosi's current DS2 uses dual Cirrus Logic CS43131 chips and has substantially better measured noise/SNR specifications, while the older DS1 uses an ES9038Q2M and supports higher maximum PCM/DSD sample rates. Those higher sample-rate numbers aren't particularly important for normal listening.

I'd buy the DS2. It is newer, quieter on paper, has excellent volume control, and currently costs less. The DS1 only makes much sense if you specifically want the ESS implementation or DSD512/768-kHz capability.

Only posting this ai overview because I just went hunting for a dac/amp . Bought the ds2 and ka13 pretty similar when using the 4.4 balanced output . My ears preferred the ka13
