it's deadly silent on my setup at work

 

HP laptop running foobar -> Wire World Ultraviolet USB  cable -> iDSD -> AKG K3003 (8 ohms)

 

Only 'noise' is when switching from redbook to dsd files, or dsd to dsd file (slight static at the start)

 

Sounds totally amazing.....

 

My ibasso DX100 is gathering dust at the moment.

iFi Windows 8.1 updated driver.

 

A new driver is coming in the next few days and once it is ready (compat with Win 8.1) then we'll update you all.

 

 New: Control panel application included.
* New: Windows 8.1 supported.
* New: Automatic uninstall of earlier version from 2.0 upwards.
* Fix: Stream format switching not working for DSD formats.
* Fix: 32 bit PCM through WASAPI was not working.

 

thank you

Hi,

 

In particular, if you are a Windows 8.1 user, please try this.

Let us know how you get on: tech@ifi-audio.com

 

Cheers

update: just tested with my IEMs (livewires, pretty sensitive). not totally black. hiss from about 11:00, but most evident at around 2:00. can hear the steps as the volume is turned up...i believe that the iDSD uses digital steps for the volume attenuation. i think iFi explained it a few pages back...i could be wrong. anyway, with my IEMs it's not a totally black background, but i presume it's due to the noisy power from my iMac. when the usb is not plugged in and i turn the unit on to run off the battery, it's dead quiet. i can also test with my iphone/CCK to see what happens.

Thanks for that update. I need to try another computer's USB port to see if my USB port is the culprit.

On headphones (AD, HD570) I never heard any noise from iDSD either when connected to PC or laptop. However when I connected iDSD to T744 post-pre-inputs (direct input to power amp) I heard noise in speakers, and that noise went away when I disconnected USB cable from iDSD. Not sure how to interpret that, some call it ground loop maybe?

fwiw, i hear the same level of noise when hooked up the iphone/CCK. but with the IEMs, 10:00 is already really loud, so whatever noise there is past that, it doesn't interfere with my normal listening levels. when connected via the SE line outputs, iFi said do put the volume to maximum, which then bypasses the digital attenuation. or something like that (the info is a few pages back...i'm too lazy to go back and look for it)

Perhaps this comparison was already made and I missed it, but how does this compare in terms of SQ compared to the E17 and/or the E18?  I am very interested in this.  Particularly the amp section is what worries me though which could entirely compromise the point of it's decoding capabilities in the first place.  On devices like this, I'm perhaps obviously looking for as distortion free and low impedance as possible.  Obviously the DNR is also important.  Thanks!

IMO the amp and volume control on this DAC are one of its strong points, at least in terms of the sound of the line outs. Curious to hear a comparison between the line outs vs the headphone outs by someone who has the kit to make a judgement. I have made other mods to my speaker crossover since I got the iDSD to let it shine in the mids. Worth noting again, the volume control is flaky down toward the lowest setting. Like the iFi guy said - you may need to use a resistor to attenuate the output and raise the volume a bit to avoid that area. I do believe, thought that the volume control in the iDSD is better than even the 64bit digital control in the JRiver.

I see, well in case I wasn't clear, I was particularly more interested in the headphone output rather than the line-out.  The idea for me would be to pair this with my Android device to use as a portable DAC/amp.  Thanks for the input regardless though!

For those of us that would like to have a few true lossless files to test the capabilities of the idsd I found this to try out or just have it available for testing your setup. I don't think you can get much better than this site....( its free )

 

http://www.2l.no/           in the upper right hand corner is the drop down box... click on Test Bench HD      after the page opens up choose the file format you want to test for the song you are going to download...   it will ask you to log in...  just put in 2L  then  2L      the download will start...   after the file gets downloaded just extract the file and use a proper player for playback... for these types of true lossless files I use JRiver Media Center 19

 

What is nice about those files is the choice of formats and the fact that the recordings have been chosen for testing purposes...   if you hear any issues while playing these files then you need to examine your setup as there is most likely something wrong in your hardware chain... it wont be the file...  

post #313 of 1720

Got a question for those that are using the JRiver Media Center 19 program with the idsd

 

1) What is the best choice in the Play Options... I'm presently using  " ifi DSD (ifi(by AMR) HD+USB Audio) (WASAPI) "  is there a better choice ??

 

2) What is the best choice in the DSP Studio...  I'm presently using  " None "

 

It seems to be working fine... just wanted to make sure this is the proper way to deliver the source to the idsd and let it do the decoding...

 

3) Any other settings that I might need to have set up ???

The amp section seems to be pretty good but it depends on what headphone you plan on driving...   for me I have the idsd strapped to an O2 amp and it works very well with all my headphones

The idsd will drive all iem and depending on what over the ear phones you have it can drive some very well... for example, it seems to drive the Audio Technica M50 very well...  not so much if I use

the DT880 or T1... but the O2 pairs very well with the idsd and can drive anything I have... 

 

As to the noise that some are hearing... my understanding is most DAC's these days turn off the output unless it detects an input signal...  so I'm thinking if your hearing any hiss noise then you might be presenting the DAC with some noise signal from your USB signal chain... easy to test this out... just unplug the USB cable from the idsd... I think this may be the reason ifi sells special USB solutions as that area can be a source for noise...

 

There are two other area's that produce noise/clicking...  1) When a song starts there can be a click as the DAC starts the decode process 2) You can hear the stepping of the attenuator when you rock the volume control back and forth at high level settings...  this really isn't a problem for me as I use the headphone jack as a line out (turned all the way up) and use the O2 volume control.  Its not a loud click... just that you can/will hear it... 

 

I like the idsd, it works well with my Iphone/Ipad/PC  it works great as a portable DAC/Amp, it works great as a Preamp/DAC for my IPad to Woo amp  setup

I don't think it would make a great commute solution, as in your pocket type solution... but it is portable for say like an airplane ride or motel stay while away from home...
