I have recently purchased a 2 year old iBasso D10 from another person, and is confused about the op amps choices. 
 
The op-amp currently in the D10 is the AD8532.
 
In the kit, i can see 2 AD8656, 1 AD8532, 1 AD8541 and 2 others whose lettering have faded away and i cannot make out what they are.
 
I have a few questions:
1) What is the original op-amp in the D10?
2) Any ideas what the 2 unidentified ones might be?
3) Which are the better sounding ones?

The originals:
 
AD8656 and Dummy Buffers.

Oh ok. Any ideas about the 2 unidentified op ams?

The D10 default opamps are: ADA4841-2 on L/R, AD8532*2 on Buffer.
inside the rolling kit: AD8656*2, LMH6643*2, dummy adapter*2.
 
The LMH6643 is typically used as buffers, however it does sound nice in the D10 L/R with bypassed buffers (dummies).

Ron, my info was from their site. But on this picture, it clearly shows the defaults as you pointed out.

I think their defaul opamp selection changed at one point.

Well, mine is probably from the older batch, since i have the receipt from 2009. The op-amp i'm using, AD8532, sounds rather nice from my meelec M11+. However, any suggested op-amps to go with my soon to come 1964-T, which is described as a neutral, darker sounding custom?

I have a long listing of various opamp/buffer impressions about a third of the way down the page here... http://www.head-fi.org/forum/thread/399315/ibasso-d10-updates-1st-page-with-current-opamp-choices-by-hiflight-images-page-1-12-13-14-15-21-71/3975

The AD8532 is most commonly used as a buffer.  If you use it in the L/R, I would suggest bypassing the buffer socket, as the 8532 can output 250 ma and can easily overpower a buffer.

Is that how the overpowering works? Granted I don't actually know how iBasso has their buffer structure set up, but wouldn't it just feed a voltage signal into the buffer?

Cool. I'll play around with op amp choices more once i receive my customs. One last question, how does the D10 stand when compared against the latest crop of portable dac/amp, portable amp units?
