Thanks @Darmur

Youāre welcome!
I just got my Rivo Plus today as well as a Keces P14 to power it. It has 4 output zones, but powering the Rivo with 5V 2A would free up a zone for something else. I was hoping to find the answer here, but didnāt, so I thought Iād post that the Rivo Plus will indeed run off of a 5V 2A power supply. Iām assuming the extra amp might be required if I was to use the usb to power a hard drive though.
Alsoā¦this thing rocks! I sold my Hifi Rose RS130 for this and it sounds way better at a fraction of the cost.
Hello, I am using 5V 3.5 amps, but, I am also using the HDMI out to a 4K monitor. In addition, I am using a 1TB MicroSD card for all my music files. If you want to save power usage, I would say turn off the HDMI out, and also use the MicroSD card for files instead of a USB stick or a USB drive that requires power (just as you said). My guess is that if you are just streaming and not using the other USB features that you will be OK, but, I do not know if you are sacrificing any sound qualityā¦
Has anyone tried using battery power supplies? What are the sonic pros and cons?
I just powered the Rivo plus with a metered USB to see what kind of current it draws. On startup it peaked at 0.9 amps, but during normal operation, using a streaming service and USB out to my DAC, itās stable at 0.5 amps, 0.6 amps when I change tracks.
This is including HDMI out to my tv.

Depends on what you mean with battery power supplies.
If youāre talking about the battery packs to boost your phone, itās not an good idea.
These battery packs often use boost converters that introduce electrical noise, which can leak into the audio signal path, especially problematic for sensitive DACs and amplifiers.
On top, if your using a rPi5, you canāt use the USB-C to power the devices (lack of USB-C power negotiation), but you need to connect it straight to the GPIO, which can cause a lot of issues.
Building an array of rechargeable batteries, can only be done with a regulator (5 * 1,2V = 6V) to lower the voltage. A regulator can again cause electrical noise.
Thanks for checking ! That is pretty low current draw. I wonder what additional it would draw with a USB stick/drive or with MicroSD car, or both ? I figure the initial .9 amps peak, then, maybe .5 or 1 amp for the drives, maybe, you can get by with a 5 volt, 1.5 to 2 amp LPSā¦
I would budget 1.5 amps for a 2.5ā HDD (spinning platter), 1amp for an SSD, 0.5amps for a thumb drive and 0.25amps for an SD card. Personally Iād consider connecting your drive to a computer and serving your library over the network if you plan to provide the Rivo plus with less power than it recommends.
Please keep in mind that peak power (when starting or heavy disk access) for HDD and SDD can raise up to 1 to 2A.
Great info, Thanks. We cannot get the Lineo5 here in the USA, so, we use the LPS we can find. Mine is āThe Linear Solutions (TLS) power supply (dual 5V rail with 3.5A each)ā and for the Rivo+, I only use HDMI out & 1 TB MicroSD card, so, I am OK for now. I use one rail for the Rivo+ and the other rail for my 13.5 inch OLED touch display.
