Thomas, one thing I forgot to mention is that Teddy Pardo doesn’t include an AC power cord with their power supply. It has a standard IEC socket so you can use whatever you want. I used a Shunyata Venom 14 on mine. Here’s what Teddy Pardo has to say about power cords:
“Thanks to the high effectiveness of our regulators in noise filtering our products are usually less sensitive to power cords. In most cases simple cords can be used. Some people reported improvements while using high quality power cords, while others reported absolutely no effect. Results may vary according to the rest of your system, so our recommendation is to experiment.”
Thanks for the information. I have a few good quality power cords that I can use in my closet where I keep my extra AV parts.
If you need any old HDMI, S-Video, component or composite cables let me know. Every time they change the standards my closet gets fuller and my bank acct shrinks.
This begins to get into the sort of territory I begin to find quite hard to justify objectively. But I have a mobo without an M2 slot and I have my HDPlex powering the mobo, SSD and PCIe card independently. I can’t quantify the improvement, not least because I don’t have the means to. But I would invite people to listen to the difference over everything powered via a smps into the motherboard.
To be able to fully service the needs of a Nucleus i7 it needs to be a 65 watt PSU. The Intel specs say the voltage is OK but the available current would be insufficient. The NUC will probably run but put any load on it and you would run out of steam. So analysis or very heavy DSP.
The HDPLEX 200W Linear supplies push 10A at 19V (190W) but if you are running other devices as well then that limit could be exceeded. as an example I run a couple of RPi’s off of the adjustable supplies or a RPi and 2 FMC’s so Im using maybe 25-30W for those, plus the 19V for my NUC7i7BNH (no internal SSD and no fan) so ambient cooling then becomes important when you start running up past 50% of the rated outputs.
Maybe I should invest in an iR thermometer device, but I’m guessing as my non A/C ambient temp is in the low 30’s C they are probably sitting around 60-70C in still air.
Forgot to attach a photo.
Current load never goes above 2A, and is around 1A in operation, Roon Core active with DSP load x2 doing 8 channel convolution and upsampling to 384kHz. NUC is a 5th generation i5, dual core, in fanless Akasa case.
Rémi that looks like a lead acid car battery charger mate(13.8V is a dead grove away there) more at home in the garage, unless the innards have been replaced with some better regulation perhaps
NUCs have a specified input voltage of 12-19VDC, and the first thing this encounters on the board is a DC-DC converter (switch mode). I’m just not sure how linear power supply can improve the SQ, especially when there’s no analog stage.
I finally pushed the button on an SBooster Linear Power supply. I went to Munich High End show and Melco were there and are now recommending using SBooster with their kit. I was very sceptical at first on how a power supply could possibly make a difference, but it certainly does. The sound stage is now deeper and the overall sound just smoother. I wondering if its possible to get a linear power supply for the rest of my system which is all audio note kit.
