UltraCap™ LPS-1 Operation and Pre-purchase thread

[mentt]

Do you mean that the LPS-1 is powering the DAC ?

Do you also mean a DAC without USB interface ?

Yes, lps-1 powering the dac

 

yes, USB as DAC will be used with microRendu

[mentt]

What about this dac Musical Fidelity | MX-DAC DAC

 

can it be used with lps-1?

Hard to say. While the back panel rating on the DAC says 2 amps, it probably actually draws much less. The question is, does it draw less than the LPS-1's 1.1A max? Impossible to know without trying or measuring one.

Ok, thank you for reply

 

what about UpTone Audio DAC as a new product :-) what do you say?

There exist a Excel overview over almost all DAC's that I can't remember who is maintain.

I think the purpose was to list which one support dsd. You may try to search or maybe someone can link to this spreadsheet.

 

You can then search up every DAC listed, and check it's power requirements. Maybe even add your findings to that list.

 

Edit:

Maybe this one:

Page 6 state less than 1 watt at max. Standby less than 0,25 W.

 

So 5V x 2A = 10W, and it uses less than 10% of what's available.

 

I expect you can make the conclusion yourself:)

(If my math is done right).

While I do suspect that the LPS-1 may be fine for the Musical Fidelity MX-DAC, that power consumption spec is for AC consumption by whatever PS is included with the DAC. Does not directly correlate to DC current draw.

Not sure which thread this belongs in but I'll start here. Also, sorry if covered already. I'm using Schiit Yggy fed by Microrendu powered by new lps-1. The Microrendu is connected to Ethernet cable to TPLink optical isolators. Content comes from tidal or NAS files using roon core on sonicorbitor controlled by iPad. Michael Lavorgna in Audiostream column powers the TPLink closest to Microrendu with an IFi microUSB3. Can someone tell me if this provides any additional benefit over that which I am already getting from the Uptone LPS-1?

Why not let the LPS-1 also power your FMC ? (Assuming you use the 10/100 version) If you draw to much power, the LPS-1 will have a red light.

 

Yes, most of us think clean DC power to the FMC benefits the SQ. Also you may remove any of these loops JS has explained many times.

 

So just use a Y split and listen for your self and find out what's happening.

[Confused]

My LPS-1 should be in the 'no later than November 18th' batch, only one short week away. I was just curious if things are running more or less to schedule? (From my time in industry I know how those pesky 'emergent unforeseen issues' can sneak up and bite you!)

Hi,

 

My LPS-1 is on its way. I am currently using a MCRU LPS 7V DC to power my microRendu. When my LPS-1 arrives, can I use the MCRU unit to power it or will it be insufficient? It seems that I need 7.5V/2.5A, so just short. Will it do any harm if I try it anyway?

 

I have ordered the compatible energising supply but, given that the MCRU is already in situ, I would like to use it if I'm able.

Sadly not, that looks like a new version. Mine is the one specific to the microRendu:

 

Linear Power Supply for Sonore microRendu + Sonicorbiter SE - MCRU

Some nice DC cables from MCRU:

MCRU Audio Grade Kimber DC Power Cable - MCRU

 

MCRU Pure Silver Audio Grade DC Power Cable - MCRU

Very hard to find any technical info on that site. Strange. I suggest you email them. Maybe a reasonable upgrade can be done.

I was thinking of just that. Can it cause any harm if I try it anyway?

A 7V supply WILL work as the feeder for an LPS-1 as long as it has a very low output impedance. At 7V the LPS-1 will be taking close to 3A (somewhere around 2.9A), if at 2.9A the feeder drops very much from 7V it is not going to work. Even though 7V will work it has to be VERY well regulated and a short low resistance cable between the feeder and the LPS-1.

 

A kind of runaway feedback can happen. As the feeder voltage gets lower the LPS-1 input current goes up, which can cause the voltage to get lower, which causes the current to get higher ... This is more of a problem at lower voltages because the current is higher to begin with. As long as the feeder can handle the high currents with very little droop this will not happen.

 

You can find a hint about how well a given 7V supply will do by looking at it's current rating. If it says anything less than 3A, completely forget it. If it is right at 3A it should theoretically work, but most 3A supplies will have too much droop. If it is significantly over 3A, say 5A, it has a decent probability of working (it may still have too much droop).

 

All the above is why the official spec only goes down to 7.5V, lower voltages MAY work, but it takes an exceptional supply to do so.

Anyone tried UltraCap LPS-1 with Wyred Recovery ?

[Superdad]

Anyone tried UltraCap LPS-1 with Wyred Recovery ?

 

Several that I know of for certain. Don't know if any have yet posted about what they heard.

[esmit]

The difference between stock PSU and LPS-1 powered Recovery, with Apple Powerbook as a source, was big when I tried. Much bigger than between a Chord Hugo and Chord Mojo, and brought the quality very near a LPS-1 powered microRendu (in my opinion).

Hi everyone,

 

Anyone tried UltraCap LPS-1 with =

 

- SOTM PCIe USB card (tX-USBexp) ?

or

- SOTM new player (sMS-200) ?

 

Have a nice day.

Hi everyone,

Yes, there are LPS-1 owners who have powered their sMS-200 with it with excellent results. Separarately, we also know of people powering their PCIe USB cards with the LPS-1.

 

Maybe do some searches in the Listening Impressions thread (I'm typing on my phone right now or I'd find some to link to).

[malarz]

Hi Superdad,

Thanks a much, excellent !

I will do some searches.

[pl_svn]

looking for a good, short, DC cable to use between my LPS-1 and Regen found this one

 

not totally sure, though, "PowerPak Pro 2.1mm C+" jack only means "5.5x2.1 Center positive" or if it's a different kind of jack that will not work :-/
