Yes it is normal to hear some clicking when switching between PCM and DSD. I had that issue before and I got rid of the clicking by system tuning and changing the buffer type and size in my case. Others will not have that issue at all. The tagging info in the beginning of the file needs to be ignored for playback.  One of the many things you can do is to control the amount of start-up entries in the startup folder. I use a program called CCleaner and it is one of the safest registry cleaner on the market. Others can make a mess of the registry big time. The free version of CCleaner is fine and under tools is the option to control the startup entries. I just diable the ones that other problems put in there that I do not need to know.  For advance users, autoruns is another but only for well experienced advance users. Take care and get the rest and hope that things will work better for you.

Thanks - will look up for the options/suggestions after I famialarize myself with my PC - again. 02:30 here, and right now I am no longer able to see anything smaller than a Jumbo Jet...

It's pretty sweet. You can also stream from your server to your phone. Pretty neat for when walking around the house doing chores.

Has anyone tried pairing the iDSD Nano to an portable external amp, more specifically, the Cypher Labs Duet? I'm quite curious with the pairing. If so, may I ask for your impressions? Thank you in advance.

 

I'm hoping the iDSD Nano/Duet combo or maybe even the standard CLAS/Duet combo would be at least comparable to the soon to be released iDSD Micro. If not, I guess I'm selling my Duet to fund for the Micro. I honestly believe the DAC section of the CLAS -dB to be slowly becoming outdated even in terms of pure PCM performance. This may not be the place to mention this but I really believe the price of the CLAS comes from the Apple licensing, balanced output, and coaxial output. Oh yeah, the CLAS -dB is now retailing for a $100 less at $599, probably to keep it competitive.

From reading the specs on the Cypher Labs Duet, the iDSD micro is going to have much more power available to the headphones. The balanced outs on the Cypher Labs Duet has the same power as the single ended outs telling me not really the full benefit of the balanced connection. In my opinion the micro iDSD is going to have much more capabilities than the CLAS/Duet combined. Check the threads here on the micro iDSD coming out in a month or so.

Last Friday me and my colleague at work, we have auditioned iDSD playing PCM and DSD tracks.

We downloaded from http://www.2l.no/hires/

"Pyotr Ilyich Tchaikovsky: SOUVENIR de Florence op. 70: I. Allegro con spirito"

in these three formats:

Stereo, DXD, 24BIT/352.8kHz

Stereo, FLAC, 24BIT/96kHz

Stereo DFF, DSD 128, 5.6448Mbit/s

The chain we used was:

Foobar2k --> iDSD --> Pan Am (Sylvania) --> Alpha Dog

First we tested native playback capabilities of iDSD, i.e. DSD track was played back using foo_output_dsd plugin, and DXD/PCM tracks using PCM ASIO output and LED on iDSD confirmed DXD, 96/24 and DSD was being played respectively.

My colleague said that the difference between DSD track and the two other was obvious for him. He also said that he didn't hear any difference between the two PCM formats 96/24 and DXD. Generally he says violin in DSD sounds like violin, while in PCM it sounds crap.

In next test I have turned on foo_output_dsd capability to convert any PCM to DSD128 on the fly, and indeed iDSD LED indicated DSD128 format being played. So we played again DSD file and then both PCM. This time my colleague says that he doesn't hear any difference between any of the three files being played. I tried my-self, and indeed I couldn't hear any difference.

Note that according to http://www.2l.no/hires/ original file was recorded in DXD, and both DSD and 96/24 files were created by converter tool.

Our conclusion

Me and my colleague we think iDSD plays DSD input very nice, and significantly better then PCM input. We think it is not the file format that limits the quality, but the DAC it-self, as 96/24 file converted on-the-fly to DSD sounded exactly the same as original DSD file. Also we see that iDSD doesn't handle DXD data as good as DSD data. Thus conclusion is that iFi iDSD would be better device if it always used DSD (SDM) part of the DAC, and always bypass multibit DAC stage. That would require that iDSD converted any PCM to DSD on the fly in same way as Foobar2k does this.

BTW, before you say test was biased I must note that for my colleague it was pretty blind test, as he wasn't saying that DSD track sounds better than that PCM track. In Foobar2k he saw all three tracks with exactly same title, and he didn't know which one is which, so he just said this one sounds better, and these two sound the same for him.

Hi,

 

A bit of background information may shed more light.

 

2L are starting out recording in Multibit Delta Sigma (6 Bit at 5.644MHz), so they are closer to DSD in nature than actual PCM. It is a hybrid format.

 

The original digital recording is then converted to either PCM (DXD) or to Single Bit (DSD).

 

Best find a handful of PCM and DSD recordings (we mean original recorded in these formats) otherwise you dont have native recording > native playback. This is the name of the game, to keep the file original throughout, not just on the playback portion as you rightly planned out.

 

So we recommend that you try a native PCM recording such as:

176.4K PCM File e.g. from Reference recordings - TCHAIKOVSKY: Mazeppa: Hopak (and for fun you can try upsampling to DSD too).

and

 

Native DSD recording:

Quad-Speed DSD256 recording from Dorm Nantes of Japan
http://ifi-audio.com/audio_blog/quad-speed-dsd256-works-by-ve-kuseru-dorm-nantes-of-japan/

 

Try these two and of course playback by natively through your Computer Audio software.

 

It is tricky as it not easy to find out what file was originally done in what and then converted before we are able to download for listening.

 

Hope this assists.

Has anyone used the iDSD Nano with NuForce's Primo 8 IEMs?

post #639 of 1711

Does iFi Nano iDSD fix "hiss" problem with sensitive IEMs yet? Or what workaround I have to use?

post #640 of 1711
They have a fixed dB attenuator coming, but not sure if it is out.

Thank you for your information.

 

@iFi: I'm going to buy iFi Nano iDSD mainly for my IEMs through Amazon:

http://www.amazon.com/iFi-Headphone-384kHz-iPhone-Android/dp/B00HI8WXVG/ref=sr_1_1?ie=UTF8&qid=1403492188&sr=8-1&keywords=iFi+Nano+iDSD

 

Will I get a fixed dB attenuator? And do I have to upgrade firmware with this batch of products?

post #642 of 1711
No, to the best of my knowledge it is not included. But I should also mention that my IEMs are very sensitive. Shure 846.

The external cable IEMatch attenuators are out, work great with my nano iDSD and Heir Audio 4.AiS, UM3X and NAD HP50.
Allow volume knob to go to 12 and beyond safely.

Where should I get IEMatch attenuator? Is it included?

post #645 of 1711
They are sold separately, and you should email an official iFi reseller.
