Dancingsea, any update? Did you compared with usb power line or any other external power supply?
Thanks in advance!
I haven’t gone too far down the power supply road yet. I’m currently going MacBook Pro —> Supra USB —> W4S RUR (powered by a Gophert switching PS with Ghent DC cables) —> Curious Link —> Matrix (usb power via the RUR) —> AQ Mocha I2S…
I’ve yet to dive off into the inexpensive Amazon based battery schemes, not convinced its worth the effort. But I really don’t know.
Even though I’m sure the Uptone LPS 1.2 is the way to go, but I can’t yet bring myself to spend $450 for a power supply for the $370 Matrix. Someone on Audiophile Style recommended this thing below. It’s the stock power supply for the Uptone LPS 1.2 and only costs $17 + shipping! It has a ground shunt. I’m going to give a try with the Matrix.
Or this, which is endorsed by Sonore, FWIW, only $159 for a LPS without the fancy batteries of the LPS 1.2:

I decided to try this LPS. I’ve got 2 other similar LPS (Zero Zone) for my NUC and external SSD dock that are excellent.

Hi Ted, why is breaking connections only at the DAC end not as good as breaking connections at both ends?
Hi Dancingsea, I ended up ordering the Talentcell battery that you checked out with Arthur at Matrix - I got a very good price on eBay in the UK. It works perfectly, no need to make any cables as the cables it comes with connect directly to the Matrix and the capacity is quite big so a charge lasts for a good 10 hours. It also has a battery level meter which shows you when it’s about to run down - with the racing car batteries there’s no indicator so you can’t tell when the battery has depleted and it’s switched over to USB power (other than by any change in sound). It’s also got an on/off switch which means you don’t need to unplug the battery when not in use, you just flick the switch.
I haven’t yet done a proper a/b comparison although I have to admit that I’ve forgotten to switch the battery on the last couple of nights and I’ve listened blissfully unaware for a few hours each time! Which to me shows Matrix is still great when run off USB power.
My ultimate aim is to try an Audience AU24SE USB with the power running down a separate cable, so that it has 2 connectors at the output end. I’ll connect the power leg to the 5v USB power output from my Melco N1Z, and hopefully do away with the external power supply altogether. But those USB cables are expensive and don’t come up second hand very often…
Regards, Mike.
The Triode Wire Labs version of this cable is worth considering. It splits the data and power as well, but also includes a 5V power filter on the power run of the cable. I have used this cable in my system and it is awesome. Plus, it is very reasonably priced.
I see y’all are discussing USB cables, maybe this helps…

I use two of those and the difference is ludicrous…
Hope this helps…
Thanks both. Totaldac looks great but a bit pricey for my budget. The Triode Wire Labs could be a possibility…
Very interesting @mike-marks, thanks for the feedback on the TalentCell. Curious to hear how your A/B comparison goes…
Thanks a lot, Robwilgus and Dancingsea!
A little over a week ago I swapped out my DSD jr for the DSD Sr. It was a nice noticeable upgrade.
A few days ago I swapped my Audioquest Rocket 33 speaker cables out for a new pair of Anticable Level Three 3m speaker cables. This made a surprisingly nice audible improvement. And the Anticables are not at all expensive. A nice surprise.
Tonight I added the Uptone Audio LPS 1.2 power supply to the Matrix and oh my! Clarity! What the heck! Better than a battery? I give up, happily.

You might want to swap that lps 1.2 dc cable to Zenwave upocc or similar for even better results. I use 0.3m long copper version and it sounds very good there.
And if i remember correctly,Audio Bacon said that lps 1.2 works best with its own power cord straight to wall and not to conditioner. Worth a try…
I cant do it because i live in europe,but found pretty good match with Acoustic Revive pc.

Might also want to consider the Audio Sensibility Signature Silver DC Cable. More open\transparent then the stock LPS cable and not as dark as the copper cable (ghent audio) recommended on the Uptone forum. I also thought the 1.2 sounded better into my P10 then the wall.
They’re having a 13% off sale at the moment: https://audiosensibility.com/blog/products-2/power-cables-2/#!/Signature-Silver-DC-Cable/p/102469015/category=2595837
With the 13% off it’s around 160 US - was well worth it

Any consensus on the right voltage to power the Matrix between 6v-9v DC?
If you are using lps 1.2,then 7v setting is optimal.
Never use above 9v or it will do damage to Matrix,that´s from their manual.

Thanks Somppsa!
I wil use HDPLEX LPS. I am able to dial anything between 6v and 9v.
I know that you can only do 7v on the lps 1.2
I was just wondering if there is an optimal voltage 6v, 7.5v 9v for it.
THANKS
The UpTone Audio UltraCap LPS-1.2 will output 5V, 7V, 9V, and 12V. There is a rotary switch that allows you to select any of these voltage settings.
Yes, I just saw a picture. What I meant was for a different voltage besides 7v or 9v which is probably what the Matrix requires for the DC input.
By the way, I am currently listening with the HDPlex LPS adjusted at 7v powering the Matrix instead of powered by the IFI on USB.
Now this is what I have.
HDPLEX powering
Two 5v lines to Allo USBridge
One 7v to Matrix
Trying to decided if the IFI setup is better or not
