If someone has a Wyred 4 Sound Remedy or bLink with iFi 9V iPower for comparison with iFi's SPDIF iPurifier, that would be very nice in deciding if the Wyred 4 sound is worth the $$$.

If iFi's SPDIF iPurifier is sold the same price as iPurifier2, then Wyred 4 Sound Remedy is well over priced.
Both devices uses Femto Clock.
Remedy's advantage over SPDIF iPurifier is it uses full size optical in and out.
Also you get a choice of BNC output.
But Remedy only output at 96k.
There is a lot of unknown i.e. price for SPDIF iPurifier.
But if it's any where near iPurifier2 or even iPurifier2 + iPower.
Then it's a good deal compare to Wyred 4 Sound Remedy.

Specs is only one thing. IMO it all comes down to sound improvement. At no cost object, that only matters IMO. If they both sound indistinguishable and both are a noticeable upgrade over just straight SPDIF then I would agree that the remedy is overpriced.
Also, one reason for Wyred 4 sound pricing is probably the made in USA factor (labor is expensive) while iFi is assembled in China.

Hi,
We had a long hard look at the affordable SPDIF reclocker market (< 600 USD) and found that all current commercial products employ Asyncronous Sample Rate Conversion and re-sample the Audio Signal to 96kHz.
We find doing so significantly degrades sound quality, as source jitter is in effect embedded in the signal and at the same time the data is re-calculated and has digital filtering applied, which causes additional distortions.
By comparison we looked at the now long discontinued Genesis Digital Lense for inspiration, which was able to pass SPDIF data completely unaltered and just re-clocked after being stored in a memory buffer. We then brought it up to date for 2016 with features such as galvanic isolation to break ground loops with co-axial SPDIF. And it has optical SPDIF too.
The 'Bit-Perfect' theme continues in the SPDIF iPurifier because unusually, it does not alter the SPDIF Data AT ALL, but simply puts the data into a memory buffer and and then uses a precision clock to clock the data out of the buffer, like the original Genesis Digital Lense.
Cheers.

Looking forward to this against the Wyred 4 Sound Remedy which does resample everything to 96KHz.

Has anybody tried this in an audio interface yet? I would think that since many of those don't have great clocks and are powered by USB, this could be a really nice addition to a recording interface. I have tried it on my USB mic, and it definitely took away some audible noise with my USB cable solution which was very nice.

Hi,
The SPDIF iPurifier will be launched at the end of July. So in 4 weeks' time.
Cheers.

Dear iFi, if I get you correctly, the SPDIF iPurifier is going to have USB input, is it correct?
So, it will not need a separate usb/spdif converter, unlike the Genesis Digital Lense.
Is it going to be marketed for less than 600$?

I wonder how much I'm losing having been sent the 'A' rather than 'B' version, having to plug in an extra cable...

Cannot tell the difference. If there is one, to me, it's extremely subtle. But, time and experimenting further will tell.

Nothing i would have thought. It's all about cleaning up the source noise, pretty sure the signal path degradation would be minimal. Have you noticed any improvement?

Yes, tidier, more coherent and articulate, however - still a bit miffed at having to have another cable in the mix - but, like you say, it is about cleaning the signal, so hopefully that second cable won't be impacting particularily

Nothing to worry. I'm an owner of the idsd micro and being the flagship ifi dac it doesn't use type-b port, back when ifi didn't have the type-a ipurifier. But the effect is as noticeable on the idsd as on my old idac2. So I guess there's nothing to worry
