How many total solutions does the iGalvanic actually solve alone without the help of the iUSB 3.0?
As in, does it take care of frame and packet noise among other things?
The reason for this is that some of us who will not be using an iFi iUSB 3.0 after the iGalvanic, but a Singxer SU-1 instead, for example. It would be nice to know that the iGalvanic is able to address these issues.
Just upon speculation, it seems as though the iGalvanic offers complete galvanic isolation, rebalance, regeneration, and reclocking but leaves things like packet noise, frame noise, and other jitter reduction solutions out for the iUSB 3.0 Micro to correct on later down the chain.
Elaborate for us if you can. Thanks so much.
In short, It would be nice if the iGalvanic was an all in one solution and that passes a near ideal USB signal that is ready for a DDC.

"Having spent the best part of two years researching, (hence why we did not bring it out earlier!), we wholeheartedly agree. The iGalvanic3.0 has been one of our more ‘technically challenging’ projects."
Woow two years researching ! PCM seem's very fragile with so mutch reclock regenerate rebalance stages (iGalvanic3.0+micro iusb 3.0)
What is the galvanic technology of the optocoupler or transformer ?

USB is in the AMR/iFi DNA - part #2
Over a decade of development
2008. The PH-77 Phono Equalizer with hi-res 24/96 ADC.
At CES 2008, we showcased a prototype of the PH-77 Phono Equalizer with built-in 24/96 analogue-to-digital converter. Vinyl + Hi-Res Computer Audio Recording- heck yes!
Below is a picture of the Tower of Power – a full AMR system consisting of CD/77/PH-77/several AM-77s and/LS-77 all in bi-amp configuration. The sound had power and finesse in spades.
http://www.amr-audio.co.uk/html/26_jan2008.html
Not long after the show, during a review of the PH-77 Phono Equalizer, we were asked to investigate a ‘system hum’ in the ultra high-end system of a reviewer that may or may not have been down to the PH-77. We dashed to Heathrow and ‘hopped across the pond’ to troubleshoot the system. It was one of the first major setups where we came across a ground loop.
AMR Director – Technology, Thorsten Loesch hit a nearby Radioshack beforehand and armed with a bunch of wires and meters, we went to pour over the reviewer’s system. We stood back and, along with our USA colleague Darren Censullo, we were on tenterhooks as our Thorsten went troubleshooting the system…it was like Godzilla ripping up downtown Tokyo. We still remember it vividly today as the system totaled +$250,000. The Tara Labs interconnects were similar pricing to the PH-77! All we could imagine was a shop sign that said:
Fortunately, nothing of the sort happened and, after our Tonmeister spent an afternoon there, we managed to resolve the issues. This incident was etched in our memory banks as we came to realise how quite common place this was. This instance sowed the seeds for USB, grounding and galvanic isolation in future products.
2009/10. The 777 – Galvanic Isolation makes its first appearance.
The launch of the AMR 777 Premier Class saw the introduction of galvanic isolation after the USB to digital audio conversion stage in the CD-77.1 and CD-777.
This required designing in ground-up and dealing with jitter introduced by isolation stages.
In 2010, the AMR 77 series also saw the 77.1 revisions make their debut for the CD-77.1 with galvanic isolation and AM-77.1.
Stay tuned, there's more!

The whole repeater circuitry in the iGalvanic addresses all these issues. However, being a "nano" range device, things like power supplies, clocks etc. are not quite of the same high level as those in the iUSB micro.
The iGalvanic nano is best considered a iUSB 3.0 nano with galvanic isolation added and operating without external power supply, something made possible by the galvanic isolation of the bus power.
The iUSB 3.0 micro remains our "flagship" USB repeater and can be upgraded to offer galvanic isolation by adding the iGalvanic 3.0.

@ iFi Audio - none of these add-ons will be necessary with the forthcoming iDSD Pro, correct? I believe it already has galvanic isolation on the USB input? Eagerly awaiting this product to pair with my iCAN Pro!

If I am to buy either Igalvanic or micro Iusb, which one should I go for?

What if I want to buy just one of your USB "correctors", between iGalvanic 3.0 and iUSB 3.0 which one would be better if used without the other in terms of versatility, sonic improvement and future proof?

Will there be a igalvanic micro 3.0?

"Woow two years researching ! PCM seem's very fragile with so much reclock regenerate rebalance stages (iGalvanic3.0+micro iusb 3.0)
What is the galvanic technology of the iGalvanic optocoupler or transformer ?"
"Neither."
Not much to say about your galvanic isolation solution, is it a top secret technology ?
Ok, this is not an optocoupler or transformer, so what is it ? A HD Valve maybe ?
Instead talking about reclock, regenerate rebalance stages than the micro iusb 3.0 does perfectly, could you give us a little more information
about this galvanic isolation solution ?

I think iFi is not going to give us all the and answers that easily...

It uses the USB isolator IC by Silanna. The UpTone Audio ISO Regen also uses this chip. I will be buying the ISO Regen when it comes out.

If it's based on a none Ifi solution, why taking about two years researching ?
