, the circuit traces do not go right to the edge, so you can quite safely make them small enough to fit the D10. dont be too heavy-handed though because there ARE traces there
My 3rd exotic Op-Amp for iBasso D10 amplifier -- OPA633
This is the little brother of BUF634 -- at one time it is OPA634
It have a higher bandwidth 260Mz compared to max buf634 of 180Mhz
Faster at 2500v/us compared to Buf634 2000v/us
But it is not as powerful 100mA output current compared to 250mA
It draws a higher current than BUF634 as well but not much.
The Pin out of OPA633 is unconventional, It is not the same as any other op-amp. And hence we need to bend the pins. By inverting the 4 connected pin it would fit nicely into the D10 without even soldering. Show in the picture are 2 simple modification and 2 with supply caps and double bypass.
How does it sound (compared to BUF634), It is more detailed, more air around the instrument and vocal but and slightly brighter. Pair better with my UM3X. But for my HD595 I prefer the BUF634.
I'm planning on getting the D10 for both home and away use (lossless rock music from ipod with lod) and I don't want to get a pair of head phones that are too good for the D10, like the HD650. Would the Grado 325is be a good pair with D10? Or is it better to get a cheaper pair, say the cheaper Grado models?
All of you guys using the D10 at home, what head phones are you using?
Thanks!

IMO, the D10 can scale well with high-end headphones. It would pair well with the 325s, but don't worry about having phones that are "too good" for the D10. It can do justice to even the best, especially with high-quality source via optical input.

I would say D4. The D4 sounds like a cross between the Pico and P-51 Mustang, and D10 sounds like a Predator. So both are very good, but the D4 is a little more open and transparent sounding like the P-51 and Pico, and D10 is a little more intimate sounding like a 3MOVE.
You can make a D10 sound more like a D4 with the TLE2142 class-A opamps, with EL8201 buffers (from HiFlight). But, you can make the D4 sound more like a P-51 with the OPA1611A class-A biased opamps with stock buffers. At
Larry, if I recall correctly, your initial impression was that the stock D4 was on par with an upgraded (rolled opamps) D10 - that was enough for me to pull the trigger on the D4 and I'm glad I did. Thanks !
To those who wants another angle of D10 Black Gate mod, here are some pics. I have about 200 hrs on mine and I can tell it is getting a lot better. I stopped using iZotope and other synthetic enhancements to my desktop system. I have the latest Topkit installed. Some few words after 200 hrs - better separation, transparency, open.
Original D10:
Original caps taken out:
Size difference among the caps:
Black Gates mounted:
Note location of the 47uf cap next to the battery:
Another angle:
Note location of the through-hole slots relative to the caps:
those 22uf blackgate bypass caps on the output are in large danger of shorting against the ground rail and other traces if you dont put some tape under them
I would suggest you stop posting in any random discussion thread to sell your d10 and iriver h120 because you could be banned.
There is proper place to sell your items in the for sale thread For Sale / Trade Forums - Head-Fi: Covering Headphones, Earphones and Portable Audio
I would also suggest you make you own listing rather borrow someone else listing as I have seen you done before.
