Anybody knows what's the difference between HM-802u and HM-802s units? All I can see on HM-802s: "HOME" label is uppercase letters now, and onscreen label "Upgraded from HM 802" is gone. Technical specifications, seems like, are the same.
I believe 802u is basically 802 in new casing, used also for 802s, plus some new dual battery design and improved digital out, leading to better specs.
802s must have some entirely new circuit as it states that power on/off is only 3 sec, the same as with 901s. I have 802u run on latest firmware and it takes forever to boot, I would say at least half a minute, and updating the media library on new inserted SD card is also not the fastest around. HM802u has a gain low/high switch, which 802s is completely missing. To my ears this gain switch makes almost no audible difference, or at least to minimal too be of any use.
I went for 802u simply because I had a super deal, got it much cheaper than what I would need to pay for 802s. The reason is that the local dealer wanted to get rid of "outdated model" because HIFIMAN is now only advertising 802s.
So as much I understand, I would say:
802u sounds better than 802, on par with 802s.
802u is much slower than 802s, on par with old 802.
