Bought the SPDIF last night...should have it early next week. I'll post some pics and initial impressions.

3. I am sure there were many discussions about where to place the micro USB power input, but the side seems like a bad choice, since it will always compete with adjacent SPDIF connections. Placing the connector on the bottom would have made it possible for me to use the coax connecter directly into my DAC, but I'm sure for others, YMMV.

Well, while there are LED's on the "top", as the RCA plug allow the iPurifier SPDIF to be rotated freely across 180 degrees, simply plug it in so the power connection is where you like and so it clears other connectors.

Yes, I know... of course, I can do that. It was hard for to consider, being OCD and all and not being able to see the LEDs. 

 
Still, it's a great product and I am pleased with the sound improvement using my HDMI de-embedder.

Hi Guys,
 
I bought a iPurifier Spdif two week ago and it really improves the sound quality of my system.
 
I use an Oppo 105D as a transport/streamer and connect via optical to the iPurifier Spdif and use an optical connection from iPurifier Spdif to the Chord Hugo DAC.
 
Would the sound quality be better if I use a Coaxial interconnect from Oppo 105D to the iPurifier Spdif and still use an optical connection from  iPurifier Spdif to the Chord Hugo DAC? The other Coaxial input of the Chord Hugo is already used by another device.
 
 
I want to make sure that it improves the sound quality before spending money on buying a decent coaxial interconnect.
 
 
Appreciate all of your guidance,
 
Thanks, Guys.

On your lines is fine - but ADD this........inside the SPDIF iPurifier is a short Optical cable. So feel free to try with your own Co-ax for yourself before you buy other aftermarket ones. We recommend keep the SPDIF iPurifier AS CLOSE to the Chord Hugo as possible because the SPDIF will deteriorate with long runs when it exits the SPDIF iPurifier (which is natural!)

Just to report my finding with the iPurifier SPDIF.
 
I bought 2 units to feed my Chord Hugo. One through the Optical and Other one though Coaxial.
 
 
The setup of the first iPurifier SPDIF is as follow:
 
1: Oppo 105D ==> Optical =>  iPurifier SPDIF => Optical ==> Chord Hugo ==> ATC Scm40 Active (Speakers)
 
There is an improvement of the sound quality having the iPurifier SPDIF in the link. Not day and night but perceptible. Tighter bass, faster pace, better instruments separation, more detailed, longer decay and wider sound stage. Livelier and more dynamic than before.
The Reclocking and the Jitter treatmen are surely playing their magic.
 
Only minor downside that I noticed is the frequent switching between different resolution 44/96/192/dsd would corrupt the iPurifier SPDIF and the latter cannot handle anymore 24-192 files. After turning off the power on the whole system, it functions normally again.
 
 
 
The setup of the second iPurifier SPDIF is as follow:
 
2a: Cyrus CDi ==> Coaxial  =>  iPurifier SPDIF => Coaxial ==> Chord Hugo ==> ATC Scm40 Active (Speakers)
 
To my surprise there is a loss in the sound quality. It is less dynamic, slower pace, thin and too bright sound. Less organic and after a 20 minutes, it become rather fatiguing, Definitely, this set up deteriorates the sound quality.
 
I tried the combination Coaxial =>  iPurifier SPDIF => Optical ==> Chord Hugo  AND  Optical =>  iPurifier SPDIF => Optical ==> Chord Hugo. But I have the same conclusion as above.
 
However the setup worth mentioning about is:
2b: Cyrus CDi ==> Optical =>  iPurifier SPDIF => Coaxial ==> Chord Hugo ==> ATC Scm40 Active (Speakers).
Sound become bit louder. High frequency piano notes are more accentuated but with longer decay than usual, brighter and less precise. Bass are less tight. After few minutes it become fatiguing. I am playing Rachmaninoff Paino concerto No 3 CD for the test.
 
Maybe the Cyrus CDi has better clock, the signal is jitter free and no noise? Or maybe.....
 
It seems that the iPurifier SPDIF is not the universal pill that improves sound quality of all equipment. It is not neutral but it can deteriorates the sound quality.
 
 
Now my second iPurifier SPDIF sits idle in the drawer!
 
Any explanation to my finding or any suggestion on how to make the most use of the my second iPurifier SPDIF?
 
 
Thanks and Regards,
 
Any explanation?

had a similar conclusion using coaxial ie thin sounding or brightness in the highs but there is improvement with the sound staging. smoother highs only happened after 3 weeks in constant use

As far as the whole process goes, both of iPurifiers do the same things in exactly the same way and it's good that you hear the input of these no matter the scenario. Point 2b indicates that the outcome is Cyrus CDi S/PDIF type dependant. Please try the same combinations without our iPurifier and see what will happen. Yet there's always the random factor in audio, the clicking of all pieces of the puzzle in the subjectively right fashion. And above all else, are used devices burned in?

Hi Railrus,
 
Do I need to constantly use it for 3 weeks in particular through the Coaxial? I just use it constantly regardless through coaxial or optical?
 
After 3 weeks, the smoothness in the highs is more sonic than without the iPurifier?
 
Could you describe your equipment?
 
Thanks for your input.

i posted this on page 2. yes i just keep using as per normal on my PC. did not enjoy as much before and lower the sound levels. however after the 3rd week, the highs seemed to have improved by then with better sound staging

@PoorAudiophile,  I agree with @railrus; after three weeks of constant use mine settled and has been very enjoyable since.

I'm liking it so far. I just sold my Hugo and got the 2Qute, I wish I could compare the two...I have to listen for a while to give any solid impressions.

Lots of toys to play with, eh? It's cool that you were able to squeeze our product in there!

I am quite impressed with this magical little box. It's added clarity/detail while listening with Tralucent Ref. 1 through the 2Qute.
 
I love the sound signature  of Ref. 1, the bass stays deep and visceral with more definition,...the mids/highs are stronger/crispy.
 
I always felt that the Ref. 1 would be the perfect IEM if the BA drivers were tuned a bit different/a little more forward. This gizmo seems to have effectively done that...clarifies and tightens up the sound.
 
I'm VERY impressed!

Hi Boomtube/Nuttinbutaire,
 
How do both of you connect to the iPurifier? Coaxial in/Coaxial out? Optical in/Optical out ? Or other combination.
 
Railrus/Nuttinbutaire, do you guys think that the iPurifier needs a break in time? I am afraid that after 3 weeks of listening, I will get used to the sound instead of hearing a real improvement.
 
I tried the Oppo 105D as a streamer and used Optical In connection to the iPurifier and Optical Out to the Chord Hugo. It sounded better than without the iPurifier in the chain. I also tried Coaxial to the iPurifier and Optical Out to the Hugo. Also sound better than without the iPurifier in the chain. The iPurifier did make an impact. I do not need any break in time.
 
But when I tried with the Cyrus CDi as the streamer, the sound quality degraded noticeably with the iPurifier in the chain regardless of the connection combination.
 
I will let it run for 3 weeks as you guys have suggested and make an other comparison with the CDi. I will report my finding in 3 weeks time.
 
Maybe the iPurifier is source dependent. It may improve or degrade the sound. But from what I hear, having it in the chain will impact the sound.
 
Cheers,
