iFi Audio Nano iDSD announced - Page 24

post #346 of 792

Received my iDSD from MusicDirect today.  Listening to a pair of RE-400 IEMs with the iDSD.  Really nice DAC.  Plenty of details and quite engaging.  Amp section provides sufficient soundstage depth and width.  I'm not going to make too many statements after 5 minutes of listening.  I hope to get it hooked up to my Bottlehead Crack amp as soon as I get some headphones for it.

 

The bad news...

My listening so far is using my iPhone 4S as a source.  When I hooked up the iDSD to my Macbook Pro (late 2013 model) it is recognized by my computer as well as by the Amarra software.  However, there is a communication error somewhere in the link because while recognized by computer the songs will not play, literally stuck at 0 seconds.  This is the same whether I try playback using iTunes or even YouTube.  All stopped, no playing.  Computer is fine, it's not frozen.

 

I also tried using a USB2.0 hub into my USB3.0 ports of my MacBook.  Same situation.

 

I knew of these problems going in but I thought going into the USB2.0 hub would be a fix so I talked myself into getting the iDSD over the iDAC.  I can live with this problem short-term but how far away is the fix?  If far away I may return and just get the iDAC.

Hi, I have been using the iDSD for couple of weeks and greatly enjoy the sound quality from this device. I have thus far tried hires tracks up to DXD and DSD64 with JRiver19 (in Windows 8) with WASAPI without any problems. But recently I downloaded a DSD128 file from 2L, and has not been able to play the track properly. The track can initially be played, but experienced lots of pops and skips, but half-way thru, everything freezes, and I can see the LED light on the iDSD flashing different colors (instead of just Magenta), seems to me the device is unable to lock-in the data-stream. At this point, the device seems to quit working properly cos' when I switch to other audio tracks (44.1, 96, 192, DXD, DSD64), there is no audio output. I would need to turn the device off and on again to resume proper operation.

 

Would like to get the experts advice on what's going on. I downloaded the latest driver from iFi which did not help. Tried playing around with JRiver19 settings (buffer etc) to no avail.

 

A side note, I don't use ASIO because in my set-up, ASIO can't even play DSD64, left alone DSD128. Wondering if anyone has similar experience. Thanks.

Hi,

 

To answer your questions:

 

1. In JRMC 19 ASIO must be set to DoP for DSD, or iDSD will not play DSD. Can you confirm this?

 

 

 

- Set DSD to 'Bitstreaming' > DoP (because under WASAPI ONLY DoP allows PCM).

 

Note: Under ASIO it is possible to use ASIO 2.1 and 2.2 Extensions combined to send DSD without DoP (it is rare though), so ASIO gives a choice.

 

2. The stuttering File, ask customer to download a few different ones? Generally, if DXD or 384KHz plays no problem then DSD128 should. Is it related to JRMC settings in 1.?

 

 

thank you.

 

Owen

Hi,

 

1. See below for JRMC19 settings (DoP)

 

2. Some new laptops with a certain chipset in the USB3.0 port does not function with USB peripherals such as the iDSD (some HDDs etc)

 

There is a possible workaround here:

We are working on the firmware but it is a major revision. If you would like to be one of the first to test it as soon as it is ready, could we trouble you to ping: tech@ifi-audio.com

 

Any questions, please ask.

 

thanks

Thanks for the quick response. Yes, I can play DSD64 tracks now after setting DoP in ASIO (I guess that is what I miss out in JRMC19).

 

But my original problem still remains... Regardless whether I'm using ASIO or WASAPI, I can play DXD and DSD64 tracks but have problems with DSD128. The iDSD device will stutter half-way through the track, with LED blinking different colors and freezes up. And strangely thereafter, when I play any tracks of any resolution even down to 44.1, there is no audio output, only way to recover is when I do a power down/up.

 

I am using USB2.0.

 

Tried another different DSD128 track from 2L, this time I can play it thru 2 times, but the third time, the stuttering and freeze up occurs again. Unless the DSD128 files from 2L have problems... Quite puzzling.

Hi,

 

Glad to help you look into DoP settings.

 

With this glitch on JRMC, can you try Foobar2k or an alternative to JRMC19?

 

Options are:

Signalyst HQ Player trial:

http://www.signalyst.com/consumer.html

 

Foobar 2K (free):

http://www.foobar2000.org/

 

or if you have access to a Mac, could you install Audirvana Trial and try that?

 

Let us know how you get on.

 

thank you

I have the same exact problem with the iDSD and JRMC19 and Windows 7.  The light will switch indicating a change in sample rate, but no audio output.   I try restarting, plugging and unplugging the cables, all manner of settings.  Finally I tried flipping the filter switch and resetting my Jriver output settings.  Voila!  It worked.  But that may have just been a random coincidence.  It has done this a couple of times.  I have eventually gotten the device to reset to normal operation, but just am vexed since I am unsure anything I actually did was the fix.  

 

Also, JRMC indicates that the bitrate output for all PCM signals is 32 bit.  Regardless of the actual file bitrate.  It is set to auto mode.  I can force the bitrate, but it won't auto output correctly.

I also am using the 2L website for free DSD/DXD files.  The DSD64 and DXD files are playing fine through JRiver on a Windows 7 machine.  DSD128 causes JRiver to pause and ask if I want to try a lower bitrate.  When I say yes it is fine and it plays no problem.  Glad I got to hear DSD files through the iDSD.  The Macbook is my primary laptop so I'm looking forward to when the new firmware is ready.

 

Is anybody hearing a difference between DSD vs FLAC from the 2L files?  I'm going to try this comparison soon.  

post #354 of 792

I am using the files from Channel Classics. I can hear the differences between various PCM rates and DSD.

post #355 of 792

Hi,I am considering purchasing a USB 3.0 cable and am wondering how the iDSD would operate in 2.0 vs 3.0. More specifically, I am wondering if there would be an increase in sound quality in 3.0 from there being more signal bandwidth, better interface, etc. 

 

Has anyone compared the two?

 

With thanks, 

Pentagonal

The iDSD is a USB 2.0 device.

I bought my IFI Nano IDSD to hook up on my phone. Everybody is talking about using Onkyo HD or FLAC player, to play high resolution files on there iphone, but the storage capacity on a phone is not enough for me. At the moment I'm using an Iphone 4s and have about 3 GB storage left, that's why I installed a steaming app called Isub. When playing high resolution FLAC files from my PC I can see on the DAC (different color lights) it's converting all the different formats/ frequencies (48kHz, 96kHz, 192kHz, etc). When playing the same songs using Isub on my iphone, the audio signal to the DAC only seems to be 44/48kHz. No matter which format I play. The Isub player itself shows the right format information, but it's actually not sending it to my IFI DAC. Active transcoding is turn off so it shouldn't down covert it to a lower bitrate. Has anybody experience with streaming high resolution files (96 to 192 kHz) to there iphone that actually also will be send to the DAC via the CCK?
post #358 of 792

I am using iPhone 4S + CCK + iDSD and it is sending 24/96 and 24/192 correctly to the iDSD based on the color of the LED.  I did have to go into the Onkyo menu and change upsampling from "48 kHz" to "off".  This should do the trick for you.

I know it's working using the Onkyo player, my question was if anybody managed to stream and play 24/96 and 24/192 files. Like for example I use Isub for this. As far as I know the Onkyo is only a player not able to use for streaming.

If I want to use the Onkyo player I only can play up to 3GB of music, because my iphone only has 3GB storage left. Isub is a nice streaming player and it enable to play all my 600GB of music files from my home. It accept to play 24/96 and 24/192 files, but it's send to my IF DAC as 16/44.
