I could be wrong though.

You should have at least gotten a DHL tracking number by now.

Seems this subject is being debated in this thread at rockbox.org (started out as a question regarding the iPod about a year ago but tody somebody asked specifically about the H1XX, and the D10 is also mentioned in there) 24/96 (HIRES files for playback...)
I'm not getting any more hires files until I know the answer to this because if it really downsamples there is no point in buying higher than 16/44.

The light right by the USB comes on when the USB is plugged in. The charge light is the one that comes on red by the toggle. On mine, after some time it will go out but not always. The one confusing thing on the D10 is the charging. I normally just leave mine plugged in to the USB.

The toggle doesn't get in the way of the 90 degree optical connectors because they are just far enough away from the body to clear it.

With my Westone ES3X the D10 and Pico are dead silent with no hiss, and the Apogee has a very slight background hiss with the volume all the way down (but not enough to interfere with listening to quiet music). Of the three, using the headphone out I prefer the D10 via optical and Duet via firewire by a small margin, both at 24/96 bit rates which allows me to hear more details with my native 24/96 music files. No more till my review is done. I'm working on the opamp rolling portion now.

than my t1 must be ultra sensitive. I heard very soft humming sound on D10 and it even louder on MisterXP. It also hiss with diablo and SuperMicroIV. Only with Reference, it dead silent. Lucky once the music start, it drown out those unwanted noise.

Thanks for answering my questions John. Really appreciate it.

Couldn't sleep last night so I listened to "Morph the Cat" in it's entirety.

A truly pleasurable listening session.
I am going to leave the OEM stock op amps in for a while before I play.

I can't believe what a perfect match the D-10 is to the iRiver. A match made in heaven.

One thing that I noticed. With my MicroDac and my Desktop, while using the optical input, when I shut the source down or pause it, there is a shooshing noise when there is no lock, but it is dead silent with the Cobra.

When you turn off the H-120, there is so noticeable sounds.

I've tried playing 24/96 FLAC files and my H120 couldn't handle it. I haven't played with this since, but either the CPU couldn't keep up with the decoding (I tend to encode everything at FLAC 8 which normally doesn't increase decoding speed much, but might for such large files), or the buffering just wasn't fast enough for such a large file. I've had no problems with 16/92 (which does sound noticeably better than 16/44) or 16/48. *shrug* I'll try again at some point, but I don't current have a means of measuring exactly what is coming out of the player.

My H140 with RockBox 3.1 plays the 24/192 flac files just fine and it sounds noticeably better that the rest of my library that is all 320 KB aac but it would be nice to know exactly what is coming out of the optical output. We'll se if somebody answers in the thread on the RockBox forum.

After reading that thread, Rockbox, in its current form, brings everything back to 16/44.

Unless someone(s) develop the necessary software to support 24/96.

 

[iriverdude]

What about the line out? It may resample digital out to 16 bit/44 or 48khz but line out may be 24 bit 192khz (if the internal DAC supports it)

 

[wuwhere]

I wonder if the MP3 player that iBasso is currently developing supports higher bit samples and bit rates.

I'm sorry for my very basic knowledge but does the internal DAC work always and with every out of the player?

 

[nc8000]

Yes the internal dac is what converts the digital file (mp3, aac, whatever) to the analog signal that is being send to the headphone out (via an amplification circuit) and line-out for external amplification if the player has such an option. What is special about the iRiver H1XX series players is that they also support a digital line-out (optical) which sends the digital signal that is normally fed to the internal dac out of the unit for an external dac to convert it and external dac's are almost always of a higher quality than the ones built into the players.

Rockbox will always truncate the sample down to 16 bits and re-sample it at 44kHz, which means it does not matter whether you are using the internal or external DAC.

 

[nc8000]

Yes that is what it seems like at the moment. I think I'll still be getting the 24/192 files as future proofing as I'm sure they will be useable in full glory sometime in the future and even now they clearly sound better than my 320 kb aac files. Wheter there is a noticeable difference between the downsampled files and one natively in 16/44 I don't know and Linn's site requires me to buy the cd again in that format. You would have thought that buying (and paying the premium) the higest bit rate you would automatically get access to download the lower bitrate songs but apparently not. Also to get a waw version instead of a flac version you have to buy again.

 

[iriverdude]

What is the DAC spec in the ibasso? Just because you're playing back 24 bit 192khz does not mean there is no downsamling going on somwhere. Rockbox may add 24 bit 192khz internal conversion but does the optical output spec support that? And does the ibasso?
