I find the stock x3 midrange is shouty and fatiguing! .... And not so clear and wide as I like ... I am using shure se535 and I don't want to carry an amp to drive those ...so is modding will be worthy in that case ? And what op amp should I get ?
and what is the output power of the ad8620 ? I am confused between the ad8620 and the one which suggested by the fiio team !!

Hey ClieOS,

 

The new X5 seems to be using the same opamp AD8397. I don't know if it would be worth it, having in mind that X5 already sounds pretty neutral, but do you think, first, that doing the same mod is possible on an X5 and, second, do you think it would be beneficial to X5's performance and sound quality? Thank you in advance for your response :)

 

Cheers :beerchug:

Not sure where you get that info, but X5 doesn't use AD8397 at all.

 

Firstly, It has a more complex opamp+buffer topology with better parts no less, so there is no reason to mod it unless you want to degrade the SQ / performance. Secondly, the idea of modding X3 is to get a more neutral sound. But given X5 is already much more neutral, that reason no long applies. Simply put, there is nothing to gain by modding X5. I can only imagine some DIYer somewhere want to mod an X5 just to try to sell it for double the money (which happened to X3, unfortunately).

Oh, damn... I just read the info page I got that info from more carefully, and it seems like I've simply misread it - you are right, they are using completely different sequence. I apologize for that ... that's totally my fault.

So..... I red that thread about 3times now ...and I have different mind now ....i am planning to use ad8066 because of its better specs and it is rail to rail but I know now that it have more bass presence than ad8620 so I don't know if its bass will mask the details like the stock X3 's op amp or not ? If so I will end by using the ad8620 for more clarity
