High speed USB Galvanic Isolation devices

[asdf1000]

Hi guys,

 

The only high speed (support 24/192 PCM and DSD128 minimum) external USB galvanic isolation devices I'm aware of are:

 

- Intona

- JCAT (based on the Intona Industrial model)

- Alldaq

- PS Audio LANRover

- iFi iGalvanic 3.0 (announced by details not yet released) - confirmed to support USB 3.0

- Uptone ISO Regen (announced by details not yet released)

 

Is that pretty much it, for high speed support?

 

I like the metal box of the JCAT (compared with the Intona) but I obviously need to wait for to hear about the upcoming iFi and the Uptone devices.

I'm ready to buy one of the above units....but would love a CURRENT consensus on whats the best way to go. I try and keep up with the threads....but many of them just go in circles and end up off topic.

 

So what is the most recommended [h=2]High speed USB Galvanic Isolation device ?[/h]

[Elberoth]

I would love to see the Intona + W4S Recovery (with ultra low noise Crystek clock) + LPS-1 in one box.

 

Right now (with JS-2 PSU powering LPS-1 and SOtM sMS-200) my system looks like a cable salad.

Lol yeh I would love an all in one like that too. I completely get the system looking like a salad too. I have a feeling the Uptone device will be isolation and REGEN (it's called the ISO REGEN I think), minus the LPS-1. Only guessing, we'll have to wait for more news.

Thanks, I hadn't seen that one.

You should all watch the Alldaq review on their website. Its kinda funny how he says it doesn't change the sound quality.

Nice. I wish more of these had metal enclosures/housings.

There is no, and won't be a consensus - it's Audiophilia.

Sorry mate, could you clarify. There is no what? And consensus on? Cheers

[r_w]

He's just saying that there will never be universal agreement on which device is best.

Ah right, I think someone else was asking which is best. I just wanted to make a list of all the options out there.

 

Too much of an open ended question, so I didn't go there lol

[r_w]

FWIW I love the Intona and W4S combo (both fed with high quality LPS), with both the USB GND and VBus 5v rails lifted (after handshake).

 

However I appreciate that this isn't a setup that will work for everyone.

Very nice combination there

[krelldog]

I just pulled the trigger on the Uptone Regen...I'll let you know what my findings are. The new setup will be...

 

Lacie/2TB Thunderbolt drive----Mac Mini/I5---Audioquest Jitterbug----Pangea Solid Silver USB----A to B-Uptone Regen---- Cambridge Audio Azur 851D----Kimber Hero XLR----Parasound Halo Integrated----Martin Logan Theos --- BTW- JRiver 22/MAC is my media player

 

It already sounds great...it can only get better.

Nice! You have more courage than me pulling the trigger, considering the Uptone ISO Regen is coming soon !

 

Not that it matters (because I still look forward to your feedback) but the current Uptone Regen isn't a USB Galvanic Isolation device like the others mentioned in this thread - it's more a USB signal conditioning device. The ISO REGEN will be both !

 

Still looking forward to hearing about it's improvements in that already impressive setup !

Sorry, I missed this last time. How are you feeding a 5V linear power supply to power the Intona !? Was there a mod needed?

 

Or did you mean the LPS feeding the W4S is flowing on to power the Intona too?

[krelldog]

But it was 184.00 shipped... not much risk. If the new one is all that..I'll stick this one in my second system.

I'm actually waiting on this...but its been delayed.

I use a split USB cable that Injects the power and GND. It's DIY but I think you can buy them off the shelf now.

Very cool. I'll do some googling. Thanks for that

You insert your ordinary USB cable into the USB type B adapter (left on the picture), so the short cable you see on the picture is used for injecting power through USB type A connector. It can be used with any good quality +5V power supply, for example iFi iPower.

[r_w]

Yes that's the type, that will work and should give an audible improvement if the PS is good quality. That one will almost certainly have both GNDs connected however.

 

I placed a DIP switch over the GND that connects to the server so I can lift it after handshake, leaving just the 2 data wires connected to the server and the 5v and GND wires connected to the LPS = complete isolation.
