Paul... We (I at least) need dsd working when we stack dx80

 

[sc53]

I just need it working through DX80 itself straight to phones. My DSD files (64 and 128) play speeded up so I can't listen to them. It was funny at first but I'm eager for next FW update to fix this. My high rez flacs play fine. Just DSD is too fast. I have reset and rescanned multiple times.

Have you tried different cards?

1.1.4, DSD128, SanDisk 128 GB Micro SD card; correct speed here.

Strange. I have 64 and 128 and they all play fine, around 90 albums.

Paul,
 
The L/R balance not working with Line OUT, i am on 1.1.4 . The moment you touch the slider it substantially lowers line output but does nothing as far as the balance.

I've got the same cards and same FW as you--the 128 Sandisk Ultras. Have not tried any others. I even reloaded some of the DSDs in case the files got corrupted.

Got all I want but no dsd

My understanding is that DSD output requires a USB connection, it cannot be done via PCM (optical or electrical SPDIF), so this would require the DX80 to also be able to do digital out over USB, which as far as I know, it cannot.

Regarding 'noises' when starting, stopping and skipping tracks.
 
As I stated in a previous post, on FW 1.1.4. with FAT32 formatted cards loaded with ALAC files, I have no issues or noises whatsoever when playing audio to headphones from the DX80 directly.
 
However, when the DX80 is digitally paired with a Chord Mojo and I do the same, I do get some audible artefacts and I can see from the way the Mojo sampling frequency light flicks that the PCM digital lock is briefly interrupted when pausing or skipping. Not enough to be a deal breaker given the SQ hike using the Mojo brings, but annoying nonetheless.
 
It seem that the DX80 does not handle the PCM digital feed particularly elegantly, because I get no such noises when feeding Mojo a PCM feed from other home devices.
 
Whether this is something that iBasso can resolve with FW updates, or if it is a HW issues remains to be seen.

Mine with fw 1.1.4 and other music format ( mp3, flac, wav) also got pop noise

I want to ask you guys before I make any assumptions: I use the DX80 to output coaxial output to my Hugo. I'm running 1.1.4. and whenever I play WAV files (which are 24 bit/192Khz or less) which are said to be supported on the iBasso website for the DX80, my DX80 freezes. Only way to get out of that freeze is to hold the off button until it turns off and this repeats whenever I try to output wav files through the coaxial output.
Additionally, I checked to see if it's the same for the headphone output and it is...
Also, it sometimes goes to the play screen which just says ready and it's empty.
So, is this what's been happening to all the players?

I really hope things get resolved before talks of the DX200 would begin or anything like that.

Can DSD be fed through USB in PCM? Perhaps DoP? Kindly enlighten me.

To do that the DX80 would have to convert DSD to PCM internally so it could be output as SPDIF only for you to then convert that PCM again externally. Double conversion would do SQ no favours obviously.

As I said, the best best option would be for iBasso to enable digital output over both USB and SPDIF. Whether this is possible via FW update remains to be seen, but as the DX80 is supposed to be able to act as an external DAC/amp (which would require digital in via USB) then this may be possible.

One for Paul from iBasso to comment on I think.

For the bandwidth USB is required for the output of a DSD signal. Using DoP doesn't degrade the signal and is a work around to carry the dsd signal on PCM. We are working on more options for the signals on DX80. The DX80 does output up to 24/196 on the SPDIF. At this time I know of no DAP that outputs a signal on USB but that doesn't mean there isn't a DAP that does this.
 
For those with continuing problems with their FW here is a link. There are instructions on using this batch tool in a folder. It wipes the DX80 and then will load a FW with no artifacts left on the internal memory of the DX80. It can also be used for the DX90.    http://www.ibasso.com/uploadfiles/20151210/201512100333294318.rar
