Thank you for the replies, it's good to know as I read of so many people that were having problems, I think more than any other device...

Is it possible to use the RCA and XLR output at the same time?
I am thinking here of the application of a subwoofer, i.e. one output (XLR) to the power amplifier and the other output (RCA) to the subwoofer.

Yes, absolutely. You can choose the output: XLR, RCA, or XLR+RCA.
I am currently having an issue where my topping a70 pro is not being detected by my computer. The firmware is on version 2.05 and my pc drivers are completely updated. The application is being detected as "Unknown USB Device (Device Descriptor Request Failed)" driver error, but all my drivers are up to date. I also have updated the firmware on my a70 pro, even though it was already on ver. 2.05, just to see if it would do anything. Lastly, it enters DFU mode whenever I plug in my usb c cable. This happens whether or not I am holding down the volume button.
Does anyone have any ideas as to how to help me or how I could solve this?

I forgot to mention that whenever I turn on the a70 pro, it goes straight to the DFU screen. The only time it does not do this is when I turn it on from the power switch WITHOUT the usb c plug plugged in. If it is ever plugged in and I turn it on, it will always bring me to the dfu screen.

What exactly do you want to do with the A70 Pro on your computer?

The A70 Pro is a pure headphone amplifier, the USB connection is only for firmware updates.
According to your description, the A70 Pro works exactly as it should.
I see, then I understood the A70 Pro wrong. But, with that said, how would I connect it to my computer or other devices? This is my first major amplifier as the previous ones were just able to connect and play. It may be a dumb question, but does the A70 Pro NEED the D70 Pro to function. When I had looked it up before, it had said it did not and could function without it.

You can connect it to the analog audio output of your computer or to an external DAC.
This can be any DAC, preferably symmetrical, but it doesn't have to be.
On ASR you can find many test reports on current DACs.

Topping hat übrigens mit dem D50 III einen symmetrischen DAC mit EQ über USB im Programm, der vergleichsweise günstig ist und ebenso gut getestet wurde wie der D70 Pro.
Ich würde das Geld sparen und in den nächsten Kopfhörer investieren.

I might just do that. After hearing about the D30 lll from you, in retrospect it would have been better for me to get the A30 lll as well as the D30 lll, to save money overall. But, considering I plan on investing into more headphones and iems, getting the D30 lll would be a good idea. Thank you for the suggestion.
