tboooe Posted January 12, 2019 Share Posted January 12, 2019 I have the HDPlex 400w DC ATX powering my music server (Roon and HQPlayer), NAA, LPS-1, LPS-1.2, Wireless Bridge, and Switch. I was thinking about getting another LPS-1.2 to power my NAA PC or this new HDPlex 200W unit. If I get the HDPlex then I can also use it to power my Switch, Wireless Bridge, and LPS-1 units, so that I can use the 400W unit just for the music server. My ultimate question though is which option would potentially sound better. Option 1 - get LPS-1.2 to power NAA, keep Wireless Bridge, Switch, LPS-1 and LPS-1.2 powered by existing 400W DC ATX Option 2 - get HDPlex 200W unit to power NAA, Wireless Bridge, Switch, LPS-1 and LPS-1.2, 400W DC ATX powering only music server Opinions appreciated. 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment

It looks like 2 rails from the transformer are used, its not uncommon to use 2 rails and then split them up further, but you can take a closer look at the wires going to the rectifiers from the transformer, it could be 4. Thank you. I see 4 pairs of wires from the transformer going to 4 bridge rectifiers. Does that mean there are 4 independent rails? 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment

Instead of a 12 and 19v fixed output I’ve asked Larry to install 2 fixed at 12v and 2 variable outputs. My plan is to use 3 rails to power the motherboard’s atx without the dc to atx converter. It needs 12, 5, 3.5v for atx plug and the 4th 12v output to separately power the cpu. Last but not least a rather complex cable like @LTG2010 suggested (thanks again for that). I also just placed the identical order. I already down the HDPlex 400W ATX linear power supply that I will continue to use with my server. The 400W lps has good noise characteristics at 2-3mv ripple. I plan on using the high quality variable output of the 200W lps for my switch and NAA pc. I will use the fixed 12V output for my wireless bridge and possible to energize the the LPS1-2 I also have. 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment

So this is not good. I wonder what voltage those caps are exposed to? This could be dangerous if it is over 35v or even if it is 35 there could be problem if there is a spike? They seem to have done this because the lead time is long for ELNA and the price is the same for Rubycon according to an email I got. Hmmmmm this doesn't sit well with me.

So last night I compared my 400W AC-DC ATX lps to the original version of the DC-DC ATX psu I had. Both were set up to power my mobo and cpu. I dont have a SATA SSD in my system. The DC-DC ATX was powered by a 19V brick smps. In a nutshell, I would say the 400W lps just made the music sound more organic. I think the reason why was because it was able to reveal more low level detail and nuance which made vocals in particular sound more lifelike. Using the DC-DC ATX, I got bored listening to the music, I wasnt involved. Of course I do not have the current version of the DC-DC ATX so that may part of the problem. Once I receive the 200W lps I will use it to power the DC-DC ATX to see if the smps is whats causing the differences I am hearing.

tboooe Posted April 25, 2019 Share Posted April 25, 2019 Last night I tested one of the adjustable outputs of my new HDPLEX at 12v with my end point which is just an i3 based mini PC. I was previously using my HDPLEX 400W lps to power the end point. The difference using the 200W lps was subtle but immediately noticeable. To my ears, the background got a bit more black and quiet allowing me to hear more nuance and detail. The music sounded a bit more organic and natural. Today I will use the other adjustable output to power my switch. The other test I want to do is compare this lps against the Uptone LPS1.2 powering my Singxer SU-1 and USB Regen.

tboooe Posted April 29, 2019 Share Posted April 29, 2019 Hi guys, please excuse me if this is a ridiculous question but I am a bit confused about the idea of adding a separate LT3045 power supply after the HDPlex to further refine the output. The basis for this approach is that the 4 LT3045s in the HDPlex are not able to meet the theoretical performance specs (ripple, noise, etc) so additional LT3045s are needed downstream? Why can't just 1 LT3045 perform the job? Is it because each one can only "improve" the power output by some percentage so adding more is required. If so then at some point we reach the law of diminishing returns. What dictates the number of LT3045 required to reach the theoretical spec? Is it the quality of the input power? Thank you in advance for helping me get my head wrapped around this. soares 1 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment

tboooe Posted May 1, 2019 Share Posted May 1, 2019 Ok I've had the HDPlex 200w lps for about a week now and I can say without a doubt that it has changed my system in a good way. I am using the LT3045 outputs to power my end point and switch. My wireless bridge is powered by one of the fixed ouputs at 12v. Previously, all three of these components were powered by my HDPlex 400W ATX lps which continues to power my server. Powering my end point with the LT3045 output provided the biggest improvement. The most impactful and satisfying change is the music has more dimensionality. Instead of being confined to a flat 2 dimensions, music now feels like it has depth to it, almost like a 3d audio effect. The other major change is that everything sounds more clear and precise with a blacker background. I am going to try adding one of the DXPWR modules for my end point to see if I can further improvement. At least for me, this has been one of my most effective upgrades. 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment

NUC can also be run at 12v too right? 12TB NAS >> i7-6700 Server/Control PC >> i3-5015u NAA >> Singxer SU-1 DDC (modded) >> Holo Spring L3 DAC >> Accustic Arts Power 1 int amp >> Sonus Faber Guaneri Evolution speakers + REL T/5i sub (x2) Other components: UpTone Audio LPS1.2/IsoRegen, Fiber Switch and FMC, Windows Server 2016 OS, Audiophile Optimizer 3.0, Fidelizer Pro 6, HQ Player, Roonserver, PS Audio P3 AC regenerator, HDPlex 400W ATX & 200W Linear PSU, Light Harmonic Lightspeed Split USB cable, Synergistic Research Tungsten AC power cords, Tara Labs The One speaker cables, Tara Labs The Two Extended with HFX Station IC, Oyaide R1 outlets, Stillpoints Ultra Mini footers, Hi-Fi Tuning fuses, Vicoustic/RealTraps/GIK room treatments Link to comment
