The connector for the battery is a male female connector that is easy to change, no solder just pull and push back into place. The battery is velcroed in.

Unless I missed something, reference to new Sysconcept optical cable  in the title is somewhat misleading. Watch this space, I guess.

Sorry, I forgot to post here, or though I did. Wait, I did post about it but it didn't show up. 

 

The new optical cable will have around 1300 optical conductors, twice that of glass, so it will have a wider bandwidth, and will have a very low modal dispersion. The bend radius is 1mm vs 2cm for the solid core. The bit rate is improved for better performance on higher digital quality recordings. It will be an improvement all the way around.

 Does all of this imply that some kind of audible difference is possible?  The new bend radius looks handy.

On higher bit rate music, it could translate into some enhanced sound quality. The signal is being transferred with less distortion, and according to the specifications, this cable would be better than glass due to a wider bandwidth. I brought up the issue to Joseph at Sysconcepts over a year ago and he has been working on it. What you hear will depend upon the quality of the equipment and the quality of the recording. I will be getting an optical cable for the toslink to mini of the iRiver to balanced dac, the Boomslang and will keep everyone updated.

Thanks. The cable sounds interesting indeed.

I wonder if the sysconcept small "u" cables in general will fit both the boomslang and D10/D12 connection using an iriver....or if different lengths are needed.  It's hard to tell from the pictures.

They both fit the same. You need a 32mm tip to tip after the bend or tip to tip on a C. 32mm is for the H140, less for the H120, about 30mm for the H120. 

 

edit: I need to state that I use velcro between the iRiver and Boomslang, D10 or D12. This adds about 2mm or so to the length, so take this into consideration.

But do you use an iSkin as well?  Another important consideration.

I do..probably close to the width of Jamato's velcro.

I don't use the iSkin but I have one here. I just let the iRivers go naked here on island. If just the iSkin then as mentioned above, it would most likely be very close to using the velcro as far as space.

I tried the Toucan today with my iPhone 3GS + Qable LOD and I was shocked by the amount of interferences I've heard. It happened too many times and each interference lasted at least 3-4 seconds. Enjoying music was an impossible task. I am now leaning towards getting the D12 because I wish to have the DAC function but I am wondering if D12 has this problem? Can anyone pairing D12 with iPhone 3GS/4 please share your experience? Thanks.

 

Was the interference picked up more by the LOD or Toucan?

unfortunately RFI has always been a bit of a problem with the ibasso gear, often it helps with different opamps than stock. speaking of which, Thats why I posted in here, if you guys havent already you really should try out the OPA1641; its an insanely good jfet input opamp with noise levels that Ti had to construct a new low noise measurement preamplifier to measure at all. when BB cant measure the noise, you know its low noise. its probably would be run slightly out of spec but good chance it'll be fine, most of the sound plus range are pretty good with lower supply voltages.

 

and yes it also sounds brilliant!! i'm a big fan of jfet inputs on chips. OPA827 is a fine example.

sorry for the noob question but can i run from the spidf out of my archos dock to the coaxial input of the ibasso d12?

Yes you can.
