I think getting into the validity of hi res or DSD is a self defeating discussion. Almost like religion. Some of us really like hi res, others say its not worth it, others say its a release by release situation. Personally I think DSD on a DAP makes sense for certain recorders, especially well recorded analog material.
By the way, there is a certain fishy discussion going on that seems to be dissing on Shanling's delivery of firmware updates. I am in the camp that has seen Shanling regularly support the M1 and M2S which, at least in theory, are current machines. I will admit that the Shanling M2 never quite got a firmware release that I thought was fully stable. But the M0 is already fairly stable and I have no reason to doubt that Shanling will keep supporting the unit, which they expect to be a volume seller.
I am also in the camp that marvels how the M0 actually sounds better than the bigger and more expensive M1. The M0 also sounds better than the HiBy R3. By all rights it should not; but there it is. So I am agreeing with the person who posted that a few comments ago.
Any thoughts about the sound compared to the Hidizs AP80. In the AP80 thread they tell that the AP80 sound should be a lot better than the sound of the M0.
(I know AP80 not released yet, but pre models existing) .
