HI,
 
Do you know what kind of info shows up on mac audio midi set up with a usb to spdif convertor. ie sample and bit rate and can it be altered in the same way that a dac's settings can. especially for breeze du-u8 or ifi convertor etc but in general for usb to spdif convertors. ive been told for eg some convertors have a fixed sample rate output regardless of sample rate input from usb side from computer. finally how do you know 100% that the convertor is actually inputting a coax signal into the dac as the dac does not show up in settings. or is that an obvious question ie the dac would not output any signal to the amp and you would have no sound if the coax signal was not entering the dac. i am completely new to the usb convertor world. thanks mk.

If you have problems with your iFi iLink, please open a support ticket on the support system. We are sure we can sort things out there.
 
Here's the link to our STS service: http://support.ifi-audio.com
 
If you have problems with a product from another manufacturer, we strongly suggest you contact their technical support. As a rule, we do not specifically comment on other manufacturers products.
 
However, speaking generically, any USB audio bridge using XMOS - disregard less if the output is I2S to a DAC chip (making it a DAC), or I2S to a SPDIF transmitter or indeed SPDIF direct output - will be subject to the same issues.
 
Digital bridge sort of a device it is not any less affected by issues on the USB side than a USB DAC.
 
However, you are naturally free to test everything in your system. You could remove the items in your chain one by one and observe the sound quality, whether it changes or remains the same. 
 
If the added devices had a real benefit in your setup, you'd like to put them back pretty much immediately.
 
Hence please do try and report back if you feel thus inclined.

Could I use this between my TV (optical out) to my NAD 390dd Digital Amp ? Thanks

if yor NAD has an optical in. Yes you can link them through ifi spdif.

I've the Micro iDSD and Micro iUSB3.0 when listening via USB input. Sometimes I'd use the iDSD's coax input to plug in my Fiio X3II. Would the SPDIF iPurifier be a worthwhile addition between my X3II and iDSD? It seems that it is being advertised to be used with products other than iFI, Perhaps the tech has already been included in the iDSD so I don't want it to be redundant or worse introduce noise instead. Can anyone throw some light, thanks.

  Perhaps the tech has already been included in the iDSD...

 
That is correct, the iDSD micro's SPDIF input circuitry is the same as the one in our iPurifier SPDIF, minus the galvanic isolation, which is not needed in portable applications. The rest of circuit, including memory buffer and clock are the same.
 
In our tests using jitter generated by the AP2 posted elsewhere (not on Head-fi) we also tried the combination of iPurifier SPDIF with iDSD micro. There was a very minor measurable difference in favour of adding the iPurifier SPDIF. 
 
This was likely caused by eliminating the earth/ground loop from not equally isolated SPDIF output of the AP2, rather than any other of the improvements.
 
So, if you need to add galvanic isolation to the iDSD micro SPDIF input, which would mainly involve mains powered equipment, then the iPurifier SPDIF may make some sense, otherwise it merely duplicates the memory buffer and clock already fitted in the iDSD micro.

Hi,
 
My SPDIF iPurifier has worked perfectly for 5 months but suddenly today it stopped working. All the LEDs are correctly lit so power getting to it doesn't seem to be an issue. But nothing is coming out of the RCA output. I then disconnected the iPurifier and just used the coax cable on its own and everything works fine again. So it seems the problem is definitely with the unit itself. I tried unplugging it and re-plugging it in several times and did the same with the USB power cable. But no luck.
 
I'm just curious about something too. Is there supposed to be electrical continuity between the ground of the input RCA jack and the ground of the output RCA jack on the iPurifier? I only ask because after it failed, I just tested this out of curiosity and found there is no continuity. I don't know if that has anything to do with the problem as that could be perfectly normal.

No, it's galvanically isolated so there should be no connection. 
 
If LED's light normally (especially the lock indicator) then the iP SPDIF would appear to be working. Could it be possible that its RCA socket was knocked a little? This could expand the RCA plugs "ring" ground and in effect break the connection.

Hi

I am looking at getting either a W4S Remedy or a iFi SPDIF iPurifier for use on an old Micromega Solo CD transport.

Has anyone compared the iFi SPDIF iPurifier fared to the Remedy soundwise?

The attraction to the iPurifier is one less cable in the chain and a lower cost.

Your feedback much appreciated.

Thanks

Refresh my memory ,can iSPDIF output both coax and optical simultaneously?

 

[stuck limo]

. Never mind. Got it set up.

Yup, it can do that!

I posted a video review about the SPDIF iPurifier just now!~ It ain't exactly as easy to describe and make a review about as the USB iDefender and iSilencer, but it does a fair job. The worse the source is, and the more high-end the DAC that is connected is, the more effect it has, and the better the final result is.

Very cool stuff, thanks George!
