iFi Audio Nano iDSD discussion + impression
Feb 12, 2014 at 8:49 PM Post #226 of 2,063
Thanks. I am a bit confused though. With the iDSD, proper Windows driver and CCK kit not all audio would be sent to the iDSD? Would I not be able to use iDSD, or Spotify or other streaming program (TuneIn Radio for example) available on my iPhone?
Why would you need a windows driver to use your iPhone?

I'm pretty sure all apps that deliver audio will do so through the cck and into the idsd. My original reply only pinpointed the onkyo app because it's what most use to deliver high bitrate files to the idsd. Using the music app or spotify, you'll be limited to 96khz, I believe.

Oops got distracted. No need for Windows driver for iPhone obviously. 
 
 
And thanks so much for all of that clarification.

Sorry - another question for the iFi guys - does the iDSD upsample 16/44.1 etc. or does it leave it alone (NOS). Just curious. I know it all has to do with the sound, so who cares. I really do dig what this puppy does with CD res. stuff. Prob. the clocks, jitter etc. Who cares. Its all good!

Hi,
 
You have the iPhone 4. With the CCK and correct audio app (eg Onkyo HF Player), then you can use it to turn the iPhone into a 'transport' + iDSD as a 'DAC'.
 
If you like, follow this linky and select the iPhone/iPad/iPod Touch.

Hi,
 
We use an Oversampling filter for PCM at sample rates lower than 352.8/384 KHz, but no "Upsampling".
 
thank you

Thanks. So for non-hi-res files & non-DSD files or streaming, will I be getting a digital output from the iPhone to the iDSD? 
 
The biggies for me, if it is easier to answer individually:
 
1) iTunes
2) Spotify
3) TuneIn Radio
 
The big appeal to me over a DAP, and before diving into DSD, would be the advantage of being able to get streaming content to the DAC of the iDSD.

@ifi audio

Have you tried the idsd with the squeezebox touch? I can't seem to get it to work. I've installed edo but it doesn't seem to work. Before I troubleshoot (as it is probably PEBKAC) I thought I'd check if it actually should work.

Ta


Yeah, helps if you activate edo. Works fine!

Using JRiver MC 19.0.108.  In Options/Audio Device, choices are
                iFi (by AMR) HD USB Audio ASIO
                iFi (by AMR) HD USB Audio WASAPI
 
Previously in this thread, WASAPI is suggested, however only ASIO has "DSD bitstream in DOP format" as an option in Device settings. 
 
Suggestions?
 
 
Wonderful device. Easy to recommend.

Thanks - that makes sense - I didnt notice a difference playing 16/441.1 native or my upsampled files at 24/192 with min phase, dither etc.

Hi all,
 
We are getting questions on the previous tutorial which related to JRMC18.
 
With JRMC19, the same principle applies BUT it is auto-configured by default;
 
Just set DSD to 'Bitstreaming' > DoP (because under WASAPI ONLY DoP allows PCM).
 

 
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.
 
Thanks to JayWillin for this feedback.

Short answer yes!
 
Longer answer - you know these do not play audio to a high-level? (for obvious reasons) So the benefit is limited.
 
You can stream hi-res with WIMP...

Thanks. Yes, I realize all of what you've mentioned. But even if I'd not get as much benefit with streaming/lower bitrate files, I'd prefer to be able to have all my iPhone audio routed to the iDSD to get whatever sonic benefits there may be.

I just got my iDSD today. First impressions... It doesn't work with my Linux Mint Nadia and it doesn't work with my N900 H-E-N. I wish there was a fix for these problems... Anyways it works perfectly under Win 8. I hope it will also work well under Win 7 in my office, but that I will see on Monday. Anyways, that all about me disappointed. Let's now get to the good things about iDSD.

I tried it with Momentums, and built-in headphone amp did the job very well, Momentums sounded better than ever before, i.e. definitely more detailed. I wasn't actually expecting these cans to be capable of presentation of such an amount of detail. Tried Alpha Dogs next. iDSD drives them well, but I could turn volume to 100% without getting deaf. Still it was quite loud, that I wouldn't normally listen at such volume, so I don't know whether it's good or bad... But, since I love complicating things I connected iDSD via RCA's to Pan Am. I have also replaced tubes to brand new NOS matched Mullards, and then connected Alpha Dogs. I have also connected digital output to my NAD T744. I started by listening to some Nightwish, then some ASOT by Armin, and now I'm listening to my dearly beloved "Tron Legacy: Reconfigured". The sound is coming at the same time from headphones and from loudspeakers that are powered by NAD. I matched the volumes, so when I take off headphones I head same sound at same volume. Note, that sound that goes to NAD as far as I understand skips iDSD's DAC. So I have comparison between how DAC in my NAD sounds on QA 2050i vs. DAC in iDSD though Pan Am on Alpha Dogs. I would say they sound very much the same, with slightly more detail on Alpha Dogs, but both signatures are very close. So, the NAD has very big, very heavy, and very efficient power supply built-in, while iDSD runs from battery. This small and not very expensive DAC in my opinion performs as good as DAC in this heavy NAD. At the beginning I was afraid it would sound too digital, but the longer I listen to it I start thinking it's very musical. It is a pleasure to listen to it, at least though Pan Am as amp.

Good job iFi! If you could only look at these issues in Linux, I would be more happy :cool:

I have a question to iFi: How can I play DSD audio? I tried Foobar2k using information supplied here, but I only got to DXD 352.8. When I try foo_dsd_ouput it just doesn't seem to work. Is there any other S/W I can use or plugin for Foobar2k?

I'm using track "Vivaldi: Recitative and Aria from Cantata RV 679, "Che giova il sospirar, povero core" from http://www.2l.no/hires/index.html. Even in DXD 3528 it sounds truly amazing. I just want to hear it output as true DSD... :rolleyes:

not intending to incite any mac/windows war, but wow, can windows make it any more difficult to output digital audio?
