Hello E-Stat,While seemingly it appears that both you and Mercman like your HD Plex LPS, it has been written over on CA, that said UltraCap has bettered these as well. And logic would seem that since both the MicroRendu and UltraCap were partly designed by the same group of guys behind UpTone Audio, I just can't see there being anything that would better them in tandem based upon a synergistic type approach design wise that is.
Which was my main reason for going away from the type of devices which required LPSs, my reason for posting my question here, was because I had only noticed one or three other mention the UltraCap, with very little if any response and was wondering why?, as it seems that most of the users of said USB thingies ( Regen | Recovery | iFi, etc... ) are using them.
I'm going to assume from what I read somewhere, that the actual MicroRendu is basically a super version of the UpTone Audio Regen!, and there are plans for another LPS as well as upgraded version of the Regen in the works........, all in all, I merely wanted to see if others were aware of said LPS?, as once again it seemed to have been overlooked.

Had the LPS-1 been available last summer, I likely would have purchased it.
My experience has been that all audio gear benefits from extremely stiff power supplies. My preamp has 40 joules (more than some amps) and the amps have a total of 500 joules.
Again, you don't seem to understand that the Regen is a powered hub while the microRendu is a streamer which incorporates Swenson's regen circuitry in its design.
Upping Joules without considering Power Supply quality is nonsense.
Who said that?
O'tay........, now I get it........, thanks boss.
IMHO one has to look at the entire system being powered. In other words, what are you powering with the power supply, and does that device already have a good internal power system, or not.For the mRendu it's not like the device is dependent solely on an extravagant outboard LPS for outstanding performance. It has excellent internal power supplies and basically needs just a good source of outboard power. Whatever you 'feed' the mRendu, there already exists well designed internal regulators and power distribution. Of course, in the audiophile world someone will be more than happy to step up and sell you another $300 - $1000 power supply but this goes back to my comment earlier about bang for the buck. I wouldn't spend that kind of money where it is not needed.
On the other hand, if the outboard power supply is being relied upon as the only means of achieving line/load regulation, ripple rejection, etc., it becomes more important, but to what degree depends on what is being powered.
Regarding your comment, " I'm going to assume from what I read somewhere, that the actual MicroRendu is basically a super version of the UpTone Audio Regen!"
This is completely inaccurate. They are totally different devices with different features and function. I've owned both.

Fair enough on the part where it doesn't include a super upgraded Regen......., I'll have to find said source of information once again, and read it more carefully then.
Recommend you read audiostream's review
Thanks to you as well agattu.
I wasn't questioning so much the MicroRendu, in so much as asking why more aren't using the UpTone Audio UltraCap LPS-1 with theirs?.
Well you did state "I'm going to assume from what I read somewhere, that the actual MicroRendu is basically a super version of the UpTone Audio Regen!"
Which is a mistaken assumption.
Ass-U-Me. Yes I did make said statement. And it's cool.
"I wasn't questioning so much the MicroRendu, in so much as asking why more aren't using the UpTone Audio UltraCap LPS-1 with theirs?."
Maybe because it's nearly $400 !! A couple Asylum inmates may decide to use the LPS-1 but it's a little pricey for my needs.
Great point......., as I've found a few of those nice little Chinese made LPSs do offer nice sonics for less then $150 or so myself. Which is again why I decided in the long run to pursue the JCAT USB Isolator, as it doesn't require one.
Have a good one Abe....
"There's am improved REGEN inside every microRendu since it also houses a USB hub that "generates a completely new USB data signal to feed your device." Great care has been taken on the tiny innards so that noise does not pollute the outgoing audio signal."
When I wrote something like Michael, Jesus at Sonore corrected me.
So I wrote the following:
Simple Design has brought together their insights with Small Green Computer and John Swenson to create a microcomputer that runs on a modified Linux operating system called the Sonic Orbiter with a built in a circuit to regenerate a new USB data signal.
The REGEN's main function is to regenerate the USB signal and provide clean 5VBUS to DACs that require it. It sits between the computer's USB port and the USB input of your DAC.
The microRendu's main function is that of a network streamer. It connects to your Ethernet network and attaches to the USB input of your DAC. However, it's USB section includes something similar to the REGEN. From CA: "The microRendu does contain a circuit which is essentially an improved REGEN."
Abe......, thanks to you as well. I see where they differ.
Jesus from Sonore was pretty specific with me when I wrote the review of the microRendu. The microRendu has something somewhat similar to the Regen, but it is not a Regen.
Thanks Mercman.
Understood....
The HDPlex is a convent garden power supply, based on a chip family that is not high performance.It is not 'optimal' for powering a device needing only a fraction of the current. A super-regulator or a shunt power supply with high bandwidth and much lower noise levels will be more appropriate.
The Regen uses a TI chip that is also not the best performing one. I bought the TI demo boards and was not particularly impressed, especially with 50Hz pickup.

The uRendu requires 1A - the section supplying 7V with the HDPlex is 2A.
He seems to get hung up on LPSs and USB cables not taking into account the bigger picture. For example, the uRendu has a few excellent onboard regulators and ground plane isolation between peripheral I/O vs the ARM board. Yeah, you can put a mega OCD power supply on it but it won't make a huge difference.
The "mega OCD" power supply is a 2A unit for the 7V rail. Like the Jokery Giant battery charger. Isn't that the current capability of the iFi?
Presently, I use an HDPlex to drive a 16TB GRAID drive, neatgear Ethernet switch, optical Ethernet converters, and an Asus mediabridge.
Tomorrow I will start work evaluating the SOtM sMS-200. I have a variety of LPS drives to try it with including the Sonore Signature, UpTone Audio UltraCap LPS-1, HDPlex 100w, and Fidelizer Nikola LPS.
I have one of these switches ordered.
No shortage of entertaining devices at my house!
