I doubt it, the recording and music distribution companies would not allow it, as it makes copying music dap to dap or dap to computer far too easy; well to them it seems to, as it would likely defeat any copy protection encoded in the music. Also there really isnt much call for it anywhere other than these type forums.

Also can anyone who has listened to both comment on the sound properties, such as which one has more soundstage, detail, clarity, highs, lows etc?
Thanks |
ok well I have both a high end DIYMOD->VCAP rig and iriver->D10 rig and I can say that for detail and clarity the iriver via optical rig wins as well as bass performance being a smidge tighter and more textured with better tonality. the soundstage on the 2 is similar, with perhaps a slight win to the teflon VCAP rig, with a regular VCAP dock or Blackgate LOD its not as good as the iriver->D10 with the bass being very present, but perhaps a little uncontrolled and sloppy. The soundstage is a bit shallower but still quite wide without the TFTF VCAP. More like a sitting a couple of rows back at a concert (with a low ceiling
) than being right there with the musicians all around you on stage.
highs have superior sparkle on the D10, but the DIYMOD->TFTF dock does have a certain magical air there that the D10 lacks. If I could mod the D10 with the TFTF caps in the output coupling; I would be in heaven!!
Overall the iriver rig is tighter, more detailed, textured and accurate with better tonality in the bass, while the teflon VCAP rig is more musical and engaging, with better bass slam better suited to rock and some electronica. both are great rigs and if I wasnt so sick; I could be happy with either one of them
these impressions are all IMO, soundstage in particular is a very difficult thing to quantify because each person perceives it in a different way, with different ears
bare in mind that these impressions are both using the Lisa III as amp with the D10 as dac only in the iriver rig. soundstage impressions are more related to using my woody recabled D2000 than IEMs, while detail and clarity I am thinking more of IEMs. these are general impressions and not something I planned out and sat down to do, just general use. I do use the iriver rig more than the DIYMOD rig; as most of my music suits it better and I can forgive the areas it loses out because the areas it wins are more and by a slightly wider margin; its also a tiny bit lighter

I'm very happy with the sound overall but cant help noticing the hiss on some of my lossless files. Really annoying and and would liketo look for the iriver as an optional choice. Although the iriver has smaller memory, I would make the sacrifice of i knew the hiss would be reduced.

the hiss is because your IEMs are such low impedance and high sensitivity, if you get hiss with your ipod and D10, you will get just as much hiss from iriver as the source isnt the cause of the hiss. What you need is an impedance adapter, which is usually in the form of a mini with female mini in the back with 2 inline resistors in it. this increases the impedance and lowers sensitivity, therefore reducing or ridding you of hisss. head-direct I think sell them as does apuresound and someone else I know, but you can find them on ebay as well. choose something in between 50-75 ohms, you will have to turn the volume on the D10 up a little and maybe use a little more battery, but hiss will be gone. I recommend you dont get a really cheap one as the quality of the resistors wont be too great and since they are directly in the signal path this becomes important. there are ones that are a short cable with the correct connections on either end, this is the type I use as it puts less stress on the jack on your amp.

If yes it will be much more the awsome!!!!!!
Edit: Does it have optical in at all??

ummm its clearly stated on th pico page and anywhere there are impressions or specs that the pico is USB only; IMO the pico doesnt have anything the D10 doesnt except a nice custom enclosure and small size. D10 is superior in almost every way as it uses the same wolfston dac chip, but has opamp rolling to tune to your headphones/tastes. With the right op-amps and buffers and using via optical D10 = win in all aspects. Even without using Lisa III as amp I prefer D10, USB performance is quite similar, but D10 with OPA2350/AD8616 still equals or betters the pico. only areas the pico (amp section) wins is perhaps a tiny bit sweeter highs and perhaps slightly better neutrality
again ^^ all IMO
