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

Just curious if anyone can comment on the sound of the new beta firmware. I've read many comments about the improved sound quality. Is it still worth doing a mod? Would you consider using different op-amp?

Cheers

The problem is that those of us who already done the mod, there is just no way to easily compare it with stock X3 unless someone happens to own two, one stock, one mod. Not that likely.

post #191 of 217

I thought that might be the situation, was hoping tho that some of you might have had a chance to hear both.

 

BTW now that it's been a while since mods have been done, how would you rate improvements to heat/battery life, and is there a list some where of compatible op-amps?

I never ran my X3's battery dry before, but overall I think it goes from the original 8~10 hours to easily over 12 hours now (and might be more). Warmth is never an issue of mine, so I didn't play much attention to it.

 

Many of the compatible opamp have been mentioned in this thread, though I don't know anyone has compiled a list.

post #193 of 217

I'll have a look through the thread again and see what folks are using.

 

Say I wanted to get a sound closest to an E12, what would be the best choice (could I just use the same opamp)?

(sorry I'm new to this whole modding thing)

E12 runs on OPA1611+LME49600, so logic dictates OPA1612 (dual channel version of OPA1611) might be a good choice to approximate the sound. But unfortunately OPA1611/1612 is not a opamp that is suitable to drive a headphone load directly. If you want E12 sound on X3, the easier way is still using E12 with X3, instead of trying to make X3 sounds like E12.

Why is no one talking about OPA1642?

I've been using OPA1641 on my Leckerton UHA-6S (MK1), they're fantastic.

 

I have the 1642 on order, will attack my X3 with a soldering iron as soon as it arrives.
