@jjtarnow The A8 already sounds excellent, so there's nothing wrong with sticking to that one. I think the room correction in the A10 might be a big deal for some people and totally unwelcome for other people, so that really depends. Build quality appears to be a big step up but again the A8 is still very nice already. I guess at this point we just don't know how much all the little upgrades and tweaks in the A10 add up to as far as sound quality.
@koestner I think Eversolo probably expects you to mainly be using the internal DAC on the A10. But I agree, it's a little weird to see that missing. They do supposedly improve the USB output with better isolation so maybe they just think that's good enough? My experience is that I2S is the best choice for some DACs but not in all cases, and they don't all work together anyway (there is no standard) so it's kind of unpredictable.
@exley_99 Agree on the website, it's annoying. The A6 used a more entry level ESS DAC solution. The A8 uses the top model from AKM. The A10 is back to ESS but using the newly released top model. Any of them have potential to sound great or not, it's all in the implementation. But I can see why Eversolo felt the need to switch, just to differentiate the A10 from A8 in that area. Would have to hear it to decide how it really sounds though.
I would think if you are a prime member it would be a painless return. And I am not sure the tariff thing was anything more than a campaign promise that won't really materialize (as is the case with most campaign talking points from most politicians throughout history). But we'll see.
