mostly depends on your usage.
(there is series from 107~109, 107 with 1 hdmi, 108 got 2 hdmi, 109?? no idea as i didnt do detail research on it, almost 99% of the review will say 109 > 108 > 107, theoretically yes, but it would best if u go try test urself, i doubted it becoz 3 looks identical, same same je, my guess is like 107 only 1 hdmi, so 108 add on alexa & 2 hdmi, mayb 109 add on extra feature again)
for me i pick yas 108
1. no available 107 stock at that time.
2. dont require subwoofer as my kid is still small, and my house soundproof not that good, if volume too loud kena complain 1.
3. up gradable to connect extra subwoofer in the future, currently budget contraint
4. turn on volume 15 i can feel my window shaking already, yea without the woofer it kinda lack of the punch, but i m very satisfy with it.
5. yamaha home theater app offer a few preset setting, i feels like movie mode is the best for both movie & music
currently in hypermood, tonight go back do another of pes2020 1st
yas sound performance @volume 10 = smart samsung nu8000 2.0speaker @volume 15~16
Me also using the Samsung NU8000 TV..
I miss my good old Sharp UE630X which had Dolby Digital Plus, DTS & TruSurround. Never had to increase volume above 30
but video quality definitely a win for the NU8000.
