"Perhaps you didn't note where I previously observed that while the nominal requirement is 1A, the device itself consumes about half that.
: And perhaps you didn't note where I previously mentioned that it's about reasoning based on specifications as I stated before here.
'I do realize and for me it's not safe since it can't even power JCAT USB Card with a single USB hard drive from Seagate (it's already low powered drive among 2.5 HDD). That's my opinion like some people who don't think bypassing fuse is OK but some do. If microRendu states it requires 1A continuous current, it'll be 2A linear power supply in my book for safety reasons.'
And not to mention additional power consumption for micro SD and some USB audio chipset that may draw current significantly like 300-500mA for playing hires format with uRendu drawing 1A in total.
"It does back to your incomplete understanding about the device and its maker's year long vision working together with the uRendu."
: You neglected the possibility of uRendu + USB input that may not work in some cases. I've been testing USB DACs in market for over 5 years before releasing Nimitra and I'm sure I haven't tested enough yet. This starts to get offensive now and I don't appreciate that.
"You're welcome to argue the merits of your claim with John Swenson since that is his assertion."
: Your assertion is 'Sure, you could throw money away, but that would not be my choice.' I have nothing to argued with $15 switching adapter from Mean Well that works good enough for its price. I recommend to compare between this Mean Well adaptor and HDPlex alone before using LPS-1 too. ;)
"At the expense of confusing the issue with facts, I don't have one nor have a ready plan to sell the HDPlex and replace it with the LPS-1.
Which returns to exactly where we started. I remain curious as to Steve's observations as to how the two compare.
Good day - I'm ready to listen to some music!"
: No wonder why you're so defensive on HDPlex. You're already using it. I see. I see. Here's my recommendation.
1. Purchase LPS-1 with energized supply
2. Configure HDPlex to send 7V output to LPS-1
3. Compare between HDPlex and energized supply
4. Sell HDPlex if you find no difference or prefer Energized supply
5. Consider Nikola as next upgrade path if you find HDPlex working better than Energized supply.
Actually, you don't need to sell HDPlex since HDPlex -> LPS-1 is possible. If you're looking for reviews about HDPlex and Nikola LPS for future upgrades, you can find one here.
exaSound e32 DAC Review has both HDPlex and Nikola in tests.
You're already using it
I chose from Sonore's recommended list as of last summer when I purchased the uRendu. BTW, you can learn a great deal about an inmate's system, room and musical tastes if you click on their moniker. Many like me post details and even pics of their systems.
Purchase LPS-1 with energized supply
Since you missed the first time around, I'll repeat:
I don't have any plan to replace the current unit because I am getting exceptionally good sound from my system. :)

: I see. Will look around later. Would be nice if there's audiophiles using good CD sources from Esoteric/Emm Labs/dCS/Wadia/Weiss too. I couldn't find matching power supply for Nimitra to recommend because I couldn't ones with designs I prefer. So, I ended up building Nikola myself so it can sound similar to highend CD transports I've known so far.

: Reading again. You're right. You used past tense and I didn't notice that before. I thought you're considering to upgrade with LPS-1.
Well, if you like current sound then it's OK. Be careful about using 7V from 15-20V too since it tends to be hotter on lower voltage, especially with 100VA transformer like that.

Using my digital infrared thermometer, the case and heat sink temperature measure 71.2 and 71.4 degrees F, respectively. By comparison, the front panel of the preamp which isn't even turned on is 69 degrees which happens to be room temperature. :)
I see. That's good then. Do you also use air conditioner? In Thailand, weather is very hot so I'll need to be extra careful about temperature.
Do you also use air conditioner?
When necessary. I live in the southern US where it does tend to be both hot and humid during the spring and summer. I get vastly more heat, however, from the sixteen 6550C output tubes than a power supply barely operating above idle while doing its job.
Then it's time to jump in the pool!
