Thank you for the link to the video. I feared that the speakers might be bad, which seems to be the case. This raises the problem which came up for the M8 monitors: if there is no external headphone jack (which seems to be the case) how do you get better sound when using this as a stand-alone TV? Obviously when a Mac is connected you can use the headphone jack on that, but what about stand-alone? This seems a strange decision
Not sure about M8 but this S9 has Bluetooth (according to the reviewer). So you can connect BT speakers, BT headphones, or a BT adaptor for linking legacy speakers/headphones.
This YouTuber being the first on S9 seems to hurt Samsung a lot more than help. Don't know why he is given a unit for review. LOL. Wait for more to come out perhaps before making a judgement.
Based on my very recent experience, these vendors (i.e. LG, Samsung) don't over engineer their designs in material use or structural sturdiness but nevertheless they're adequate and don't bother me at all in daily usage. E.g. how often are you deliberately shaking your monitor..just to see how quickly it dampens down to still steady state? Apple over engineers ASD like a brick of metal, which isn't necessarily a must-have or a yardstick for a display.
The reviewer also said the S9's base is aluminium. On this he's lots better than other reviewers of 4K monitors. The other YouTubers will claim their 4K monitors come with plastic stands. LOL. None of them are correct. This S9 seems to come with a stand made of steel internally and wrapped in aluminium sheets. The base definitely looks like steel to me. So it could be made thinner (to save material, weight & cost) but structurally strong enough for support.
Incompatibility with Intel Mac is real oversight. In the era of launching a product first and beta testing it while we ship, I'm still kinda surprised by Samsung. I think it's just a firmware fix.
Anyway, if the price is not far away from ASD, this S9 would be hardly attractive.
