In Reply to: RE: UpTone new ISO REGEN ($325) "borrows" concept from Intona ? posted by AbeCollins on April 24, 2017 at 21:21:16
Get this right for once. The concept has not been borrowed; it is well established practice for noisy computers attached to the mains and downstream equipment.
Just because yopu use a noisy computer system with a fan doesn't make the Regen useless for others. It may be the case for you whereby the Itona's isolation helps to improve your system.
The pictures you posted are already on the web and you can help AA financially by not wasting storage space and bandwidth and by posting some elements of truth rather than speculation and repitation.

"The concept has not been borrowed; it is well established practice for noisy computers attached to the mains and downstream equipment."The point was that UpTone decided to use a silicon chip for the isolation design. A design choice that Intona made years ago. Comprende? Probably not.
"Just because yopu use a noisy computer system with a fan doesn't make the Regen useless for others."
What's a "yopu"? No I don't use a noisy computer system, not compared to your 39-Lb Dell beast with massive blowers anyway!
And I never said the REGEN was useless for others. I said I found the Intona to be more effective in my system . And some others here in the Asylum have experienced the same in their systems when switching from the REGEN to the Intona.
"The pictures you posted are already on the web and you can help AA financially by not wasting storage space and bandwidth..."
I've been helping AA financially for well over a decade. You haven't contributed a dime.
No kidding those pictures are already "on the web" because I put them there! But they do not waste storage space or have any financial impact to the Asylum. Those photos are stored on MY webhosting server and are simply "embedded" in the Asylum webpage.
Hint: Right-Click on the image, now "copy image address" or "copy image location". Paste it into your web browser URL field. Where is the imaging coming from? It's not taking up storage space on AA.
Comprende? Probably not.

It seems like before one guesses on what motivated Uptone to pursue this path, one MIGHT want to read their posts about the device:https://www.computeraudiophile.com/forums/topic/31589-iso-regen-launch-thread-product-web-page-up-photos-etc/?do=findComment&comment=655017
Where Alex posted:
"A somewhat shy reader just sent us a question via PM and asked that we answer it here on the forum. Here are the questions copied from his letter:
Like most I am trying to get the best bang for my audio dollar. So why didn't you and John simply wait longer and build the Iso Regen to begin with? This is my question.
I hope instead of responding to me that you will post your answer @ CA for everyone to see. My belief is that your answer will help create additional trust from your customers as they decide why and whether to spend another $300 for a product you have supposedly improved in a short time since you asked for $200 for the original Regen.
The answer has two simple parts:
1) The Silanna high-speed USB isolator chip did not exist when we first developed the original USB REGEN (I found out about it in December 2015, about 2 months after the chip's first announcement);
[And while John and I discussed early on what it would take to offer galvanic isolation--an FPGA and bunch of development time; (this was 7 months before the Intona--which takes that approach--was ever announced), we decided against that.]
2) When we were designing the first USB REGEN at the end of 2014, even the Linear Technology LT3042 ultra-ultra-low-noise regulators had not yet been announced (they became available in April 2015);3) While we knew that a quality, low-phase-noise clock would be helpful for the REGEN, it was not until much later that we considered that using a world-class clock would be significant.
As for it being a short time from the USB REGEN at $175 to the ISO REGEN (with 4x the parts cost) at basically $290 (if you subtract out the $35 retail USPCB being included with the ISO REGEN), I would hardly consider two years between product introductions (April 2015 - April 2017) as being a short time.
I hope the above forthright answers are helpful to you Shaun. And please, do join up here at CA and feel free to ask anybody anything. CA members are a friendly bunch--especially to "newbies" and we don't bite! :)
--Alex C."So yes they did consider the same scheme as the Intona (before it was released)... and ultimately the Iso uses an entirely different isolator mechanism and chip.
I don't have a dog in the USB audio hunt as I don't use USB in any of my computer audio setups. BUT I have a lot of respect for what John & Alex are doing with their Uptone Audio products and those that fit in my setups (like the LPS-1) have been very beneficial.

I didn't have to read posts by UpTone to arrive at the same conclusion.... but thanks for posting comments that support what I determined through my own research.... and already posted in this thread.
The single-chip solution that simplified the implementation of a silicon barrier based USB galvanic isolator was not available when UpTone released the first REGEN. I already stated that in this thread. It wasn't available when Intona created their USB isolator years prior.
Intona created a silicon barrier USB isolator years prior through a lot of their own R&D and by using more components. The 'chip' Intona used wasn't much more than the silicon barrier itself. They had to create and program their own supporting logic (via Xilinx FPGAs) for USB protocol conversion then reconstruction back to USB. The new chip that UpTone uses has all of this capability built-in.
But the resulting concept is the same... USB galvanic isolation over a silicon barrier. Now that the single-chip device is on the market, we will see more of these USB isolators as they are easier to implement.
"Now that the single-chip device is on the market, we will see more of these USB isolators as they are easier to implement."Indeed, yes - I have an isolated USB hub (ISO-HUB) on tour. This is different insofar as it is powered directly by battery, no voltage regulators in between - this makes a great difference as anybody who has heard the prototype can attest (and my thread here on bypassing the voltage reg of the Regen with direct battery power) & I termed it optimised isolation
An isolated power supply (ISO-PS) is also part of the new offerings as is an isolated DAC (ISO-DAC) & isolated SPDIF converter (ISO-SPDIF) - all battery powered & all using optimised isolation. These last two products are world firsts - isolated high speed DAC & converter

First impressions coming in here http://www.tirnahifi.org/forum/viewtopic.php?f=8&t=4240&p=83516&sid=d3647ccb7aac6afa0c7c9164d56ce25f#p83515
"Straight away yesterday I could hear the difference, the 2 words that come to mind are a fuller and natural sounding presentation.
There is definitely more body to music and a very natural sound, dare I say it very analogue but with all the detail and more.
Not sure how many hours you have on the units but it sounds even better today, maybe the batteries are now fully charged but even with them charged it sounds like it is still improving.
It is definitely a step forward from the prototype we have heard on several occasions over the last year."

"Very happy now with the sweetness and the way notes hang that much better in the air with the ISO Hub so I will be handing it back to John at the weekend for next in line."
