In Reply to: RE: I use an HDPlex linear posted by el34eh@yahoo.com on February 27, 2017 at 07:07:14
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!
