I am almost salivating reading what you guys are writing about the iriver/d10 combo
And it jumped £24 within the last 15 seconds, good job I had left plenty og leeway to my max offer.

you need to with those old irivers, always in such high demand.
As a side note, a view often expressed over at misticriver and which has much merit, is that if a manufacturer could produce a dap along the lines of the old irivers re large capacity, multi functional with high quality connection options such as optical they would be quids in. It wouldn't take much doing either, this isn't new technology, its all been done before and could complement their existing product lines.
Imagine the kind of players we would be seeing today if iriver had chosen to evolve their h series players as opposed doing away with them, it almost doesnt bare thinking about for the techy gadget lovers amongst us.
I spent some time today going thru my supply of opamps that might be compatible with the D10.
The list below is certainly not all-inclusive, but is a pretty good representation of the ones that will function in the D10, considering the low supply voltage.
I evaluated them without buffers, so as to hear the true signature of the opamp. I used high-bitrate music, both instrumental and vocal fed to the Aux input of the D10 from my iRiver H-CF32
As I only wanted to evaluate the amp section, I did not use the optical output of the iRiver.
I will say at the outset that the circuit design of the D10 flattered whatever opamp I tried; there were no bad ones in the bunch.
Some that I thought might work didn't, and some that I doubted would work did....go figure!
I used both my Sennheiser IE8s for IEM, and my recabled Grado RS-1s for full-sized phones.
As I do not want to get into subjective "which is best" discussions, I simply ranked them based on treble vs bass balance, or from brightest to darkest.
My ranking is as follows:
ADA4841-2
AD8599
AD8616 (good buffers)
AD8397 (built-in buffers)
AD743
LMA6643
AD746
TLC2202
LTC6241HV (LTC6241 would also work just fine)
EL8201 (good buffers)
OPA2111
AD823
OPA2604
THS4032
OPA2134
LMH6655 (good buffers)
AD8656
AD8066 (with AD708 buffers)
AD2228
AD2227
OPA2350
Widest soundstages were found in AD8066, OPA2111, OPA2604, AD8656 and AD746, respectively.
Opamps that I thought might work but didn't: AD8620, LM6622, LME49720 (LM4562), AD797 (SOIC) OPA627 (OPA 627 initally worked fine, but only for a short period of time. Likely on the very edge of its voltage envelop with a fully charged battery.)
Note that the AD8397 has built-in buffers, so I would not suggest using additional buffers. This opamp has sometimes been criticized for its highs, but in the D10, it performed really well.
My recommendations:
If you have bright phones and/or are a basshead, go with the darker opamps, if you like detail and sparkle, or have dark phones, try the brighter ones.
Pioneer HDJ-2000 with iBasso D10 - a good combination?
Got my Pioneer HDJ-2000 headphones today and now I'm wondering if you specialists out there can shed some light on how suitable the iBasso D10 would be paired up with this. Pioneer HDJ-2000 specs.
where do you guys buy your op amps from? When the d10 arrives it will be the first amp I have had that allows me to roll the op amps, and would like to explore a couple of the options listed in HiFlights post.
I see the d10 comes with the AD8656 so that sounds like a good one for power and bass which I am interested in, but still, would be nice to see what different sound signatures can be derived from the op amps.

I just wrote iBasso to inquire on when I might receive my amp and instantly got this return message:

Can you get 1.8" IDE to SD adapters? Because using the CF mod and then an an SD to CF adapter will still make the system limited by the CF maximum capacity of 137gb.

....
Thanks for the effort, HiFlight. Noticed that you didn't list any single supply OpAmps; is this because there isn't space in the D10 for the use of 2-to-1 adaptors? If so, did you try using a few of your favourites, e.g. AD743, AD797 without the case attached, just for the fun of it?
