D10 optical problem - Page 2

think i gotcha. optical, usb and coax are all digital. if this glitch can be recreated using the same circumstances for each of the digitally controlled inputs then it would narrow it down to the circuitry between the dac and the left channel of the amp. the theory is sound afaik.

yep; you got it, if it isnt confirmed there; then there is something really very strange going on. i'd almost bet my left nut he'll confirm this, because I cant think of any other connection that would be present from the optical to the left amp channel, considering the left channel works with the aux fed by optical. so going by that, both the dac and amp circuits are fully functional. i'd be happy to call it confirmed if its mirrored with one more digital input, USB OR COAX.

When you are using the optical input, is there another digital source plug into the coaxial input? I have had experience with other DACs that have manual switching between coaxial and digital inputs where when both sources are on, the DAC cannot get a good lock. I have also had problems with certain tight headphone jacks that when I thought the headphone was plugged in all the way, it was actually only plugged in 2/3th of the way (which of course will only give me one channel of sound).

The fact that you CAN get both channels even if by barely touching the headphone jack means that the unit probably has no problems between the DAC and the amp section and the problem is at the headphone connection and/or the digital receiver. Just my 2 cents

what?? he gets both channels when using the analogue line in AND when using the aux out. you ^^ are not making sense and I dont know where you are basing the info that its working when barely touching the headphone jack. hes saying that its almost pulled out; not that he isb arely touching the jack. so the tip (left) and ring (right) are both contacting the right channel terminal. 'm not sure if you are replying to this thread. the D10 has automatic switching and he has already been through when it works and when it doesnt. either you havent read the thread, or you are missing something

The man from Brisbane wins the diagnostic prize!

Same problem with the coax input.

Anything that I can do about this myself?

^^ lucky; I wasnt looking forward to surrendering my left nut

not really much I would recommend you do about it yopurself; I would send it back to ibasso along with a link to this thread. they arent taking any new orders at the moment because they have run out of soe components, so they should be able to fix it quickly and get it back to you. hopefully they consider it fixable and its as simple as a bad solder joint, otherwise they wont be able to replace your amp until they get the new parts. maybe email them first to make sure they will be able to sort you out, otherwise might be better for you to hang onto it and at least be able to use it as amp only. as fixing it may not be tghat difficukt,m but would definately void your warranty.

^^ lets keep all the nuts in one place, thank you

i would email now and get an rma asap. find out a rough estimate for turn-around time and see if they are willing to cover the delivery costs. hopefully you will have your d10 back soon. i would not try to fix it yourself as you want to keep that warranty if god forbid anything else goes bad with the d10 down the line.

yep; get the RMA and fill them in whats goping on. they should cover return postage so soon after you bought it, but some companies are pretty slack about that.

your welcome

this thread is an example of the very best things about the forum. hope it goes well and let us know how it goes with ibasso. i have a d10 too so it would be helpful to know the rma process, just in case

no problem on the help mate; all in a days work LOL. actually I get a bit of a kick out of diagnosing problems with stuff. and since I know how the circuit works on D10 it really wasnt too much trouble. apparently even if they have to replace it, they are expecting to be shipping new D10s again in mid may.

Just came across this thread and I had the same exact issue (I think). I ended up returning it to iBasso, got a replacement and have been happy ever since.

To put an end to this thread, I returned the unit to iBasso, they fixed it and returned it to me. Excellent service. First, they did this in two weeks. I put it in the mail on May 8 and had it back on May 21. Second, they fixed it and did not replace it, as I suspected they would. I had over 300 hours of time on it and I wasn't looking forward to having it out of service for another couple of weeks.

what is this thing where people dont use their amp while burning it in?? I really dont get it; I always burn things in just by using them. occasionally i'll givem some pink noise while i'm asleep, but I really dont understand why people dont just use them, its not like playing it music instead of pink noise is going to damage the performance of the amp. I think its funny BTW, the I have a similar problem, when I use the analogue line in; I have to fiddle with it or I only get one channel. so i'm gonna have to send mine back as well. It sux because it wont be cheap from here either. its all well and good to have good after sales service and that is truly a marvelous thing and ibasso have it in spades; but I would prefer for it not to happen in the first place. and yes, the digital ins work and I get 2 channels at all times

Great thread over problem tracing and getting heads point in the right direction. Sorry to hear that qusp about your unit's defect as I can imagine it's really hard for a to and fro from Aus to China.
