Me too.  Have been searching for years.  And I have contacts in China--with the sort of firms that actually machine connectors for the rest of the world.  Most all of what you see in audio plugs--from resellers and brands really are made by just a few factories.  Here is one of the real ones: http://www.aecconnectors.com.tw

Haha cheers, here is me trying to be useful for a change.... .

I see the nightmare our purchasing department have getting parts. Smaller beautique MOQS must take a lot of effort. I am just a low level manufacturing engineer. I am trying see if I can remake older engine controllers.

Dies 20 years old for IC's to keep a plane going, obsolete parts driving buyers insane. I am glad I just see if we have tooling..not searching around the world for bits.

Cheers for the Y cable advice..?

Cheers

Just ordered two of the new USPCB adaptors. Gonna compare them to the Curious Regen-Link full loom.

How did you do that?  I don't see them listed on the Uptone website...You got a secret connection?????

[SWL3600]

Yeah, something weird is going on. I'm waiting for Alex to get back to me. Right after I ordered it I went back on the Uptown site and it was gone. I'm sure Alex will clear it up.

Right when I thought I was special.....

Sorry Scott, they are not available for pre-order just yet!  I was working on the web page and forgot to make it "invisible."  I just refunded you purchase.

 

Trying to get the pages up and the rollout going.  Might as well tell you guys the news here even before I start the official ISO REGEN launch thread:

 

The USPCB is going to come "free" with every ISO REGEN! 

 

Price to order it separately--and not until after the first wave of ISO REGEN units is out the door--will be $30 or $35 (I have to see how much final labor is involved with the heat shrinking and DIP switch hole punching).

[SWL3600]

That's exactly what I figured what happened. Thank you for clearing that up and refunding my money.

And here I thought we were getting a free LPS-1 with the ISO-Regen.

 

But kidding aside - that is awesome!

[Middy]

You have to be careful with these top flight hard nose corporate marketing exec types. It will be a free pen next....

 

At this point, getting an ISO people would sign the cheque with the blood of their first born. ?

 

A lovely gesture though SD  but iso demand is going to out strip supply unless you have a South American cloning facility and a gallon of John's stem cells...

Me... I am trying to convince the wife an ice bath and 1 less kidney is is great for weight loss and Krell speakers...?

Looks like someone refreshes uptone's website page quite often.

I think that's quite ok price. Especially if it can beat many overpriced USB cables. 

The Nordost Valhalla 2 USB is $3500. ?

 

Due to fright cost it would though be nice if you can order a second one together with the ISO regen.

(Of cause I could order 2 ISO,  ?)

 

[Middy]

I  sure the old regen users want a bite of this apple too. Lovely to offer it out with the Iso. 

Practical over Nordost cable porn any day. Even if I won the lottery. ?.

I am suprised Nordost even print prices.

If you have to ask you normally can't afford it..

I know it's soon Gents but some info. . anything..?

Or people start posting that picture about taking money every other post..

Hi @Superdad

 

Can you share some more info on the REGEN part of the ISO REGEN, in particular what's improved over the original REGEN.

 

I saw a couple brief comments earlier in the thread that it's better but not much more info than that, like why and how it's better, if you are able to share.

 

Thanks !

[Superdad]

Hang in there guys.  ALL the info you want will get posted before the end of the weekend.  We'll begin accepting orders on Tuesday, so there is lots to get ready.  First boards off the production line arrive in the morning, with the full first 250 PCBs coming next week.

So I can assure you all: this is very real and not just a drawn out ruse--even if it seems like that sometimes.  

 

Thanks,

--Alex C.

This is really no different than doing the same chain with a USB REGEN--except in this case the ISO REGEN is using 5VBUS power from the microRendu to power the upstream side of the ISO REGEN's isolator chip. (Whereas the USB REGEN does not use any VBUS power.)

 

 

Hi Alex, a question about this.

 

Does this mean an LPS-1 powering both a LANRover and ISO REGEN won't work?

 

Since the LPS-1 will be set to 7V output, the LANRover won't be outputting 5V to power the upstream side of the ISO REGEN.

[Middy]

Hey would never think that. Just hungry for info and how you are both getting on.

Thank you for the update Alex and apologies if it added any  pressure. 

Just happy it's going great for you both at a busy time but not too much fun.

So happy now I have had the LPS 1 for a few days ..just excited about the ISO..

Good luck as always

Since the LPS-1 will be set to 7V output, the LANRover won't be outputting 5V to power the upstream side of the ISO REGEN.

 

Here is the full break-down regarding powering both the downstream end of a LANrover and an ISO REGEN from a single LPS-1:

 

a) Because--per Paul McGowan--the LANrover (downstream unit) somewhat oddly outputs 5VBUS power directly from the 5V the box is fed (either the SMPS wart is comes with or a user-suppled better PS), with only a filter cap and ferrite bead, an LPS-1 used with it would normally be set to 5 volts so that the LANrover's VBUS out will be 5V.

 

b) The VBUS current draw of whatever DAC/DDC is connected to the output of the ISO REGEN is going to determine if it can be run from (a shared from LPS-1) 5V or if the LPS-1 should be set to 7V.  That is because when fed 6+ volts (via the DC jack) the ISO REGEN's TI TPS7A4700 regulator for VBUS output can provide up to 1A for DACs that need it (even though USB max-spec says DACs/devices are not to draw more than 500mA).  But when fed just 5V, that regulator does not have any drop for regulation and will put out just 4.95V--and that's only if the draw from the DAC is minimal.

(This was the tested case with the Singxer SU-1 you were noting; the SU-1 just needs to "see" VBUS voltage and 4.95V was fine.)

 

c) But given that the upstream side of the ISO REGEN consumes so little current--the LT3042 reg on the input side of the "moat" is just using VBUS to create 3.3V for the isolator chip, it probably is fine for VBUS into the ISO REGEN to be either 5V or 7V (have never had 7V on VBUS so I should check with John, but the extra 2 volts to drop with the datasheet spec'd 40mA draw is just another 80mW of heat to dissipate on the reg/PCB).

 

d) The above does not consider if the linear regulators the LANrover does have--for its actual active circuity (at 3.3v)--have enough heatsinking to be okay running from 7V instead of 5V.  As with the ISO REGEN, it is likely fine, but I am sure the LANrover circuits consume more current overall, and I'm not comfortable advising someone to exceed voltage input on a device other than our own.

 

e) The downstream side of the ISO REGEN with its 5 regulators running everything is fine with anything from 5V to 9V (as long as DAC connection needs detailed in in "b)" above and in the FAQ on the overall subject are taken into consideration.  

So if I had a LANrover and ISO REGEN that I wanted to power from a single LPS-1, I would start with it set at 5V.

 

So Sean, if there is anything about the above that is not clear, please just read it over an extra time or two.

 

-------------

 

FedEx just dropped off the first samples of the production ISO REGEN PCB (and I immediately stuck one in an overnight envelope up to John for the flashing code), so nobody is going to hear from on this forum for a day or so.  Then I'll close this thread and open the official ISO REGEN launch thread by the weekend.

Assuming no disaster in the boards I am about to test, we will open it up for ordering this coming Tuesday, April 25th. 

 

[Middy]

Nice?

[Superdad]

Oh wow!  The production boards sound even better than the last preproduction piece (which admittedly had a few hacks on it). 

For several hours I've been listening and comparing--to original USB REGEN, to with and without LPS-1, and to several popular competitive products (sorry, don't ask me to directly comment)--and all I can say is that nobody is going to have ANY trouble hearing what the ISO REGEN does!  

Like when I first started listening the original USB REGEN, the ISO REGEN is so different that it makes one question the truth of the presentation and the recordings.  I found myself swapping to something else and going "Okay, so is this more correct?"  Then I'd go back to the ISO REGEN and discover more and realize that it pulls apart complex pieces and arranges the instruments in a fashion where the players and the instrumental tones make more sense and are more natural.  Sorry I'm not able to describe it well, but you all will have a chance to find out for yourselves very soon.

 

By the way, we did put a DIP switch on the back to defeat the isolation if necessary in extreme circumstances (another time I'll talk about our experiences and what those circumstances might be).  Most people will never have to use the switch, but there to it is interesting to be able to hear what the galvanic isolation brings to the table.  The ISO REGEN is so much better than everything else the original USB REGEN (for a host of reasons that will be detailed again soon), so folks will get to hear the perhaps 20% benefit that comes with the isolator.

 

I was a little nervous up to now--and there was something about John's final hacked-up board I'd been using that just did not completely gel for me (I chalked it up to still getting used to the Singxer SU-1/Holo Spring combo).  But with the real and final board playing in my system I am "over the moon" and confident that we have another big winner on our hands. 

 

Onward!
