Thanks for the input, I was worried I'd need to buy a more robust DAC to properly supply a tube amp down the road.
I'm still just a bit confused about the best way to keep the D12 plugged in. I've looked at several of the amp manuals and a few of them state to make sure to keep the switch in the off position to maintain battery life. When I do have the switch to off and the usb power adapter is plugged in am I discharging battery still? I'm a bit confused and concerned I'll damage the amp if I don't set it up right. I still can't get over all the little extra's ibasso threw in and am reading up on opamp rolling
I read through the thread and I don't think anybody answered your question, which I was curious about too.
I believe that if you plug the D12 through USB (to say use it as a DAC/amp unit) with the charge switch off, it will run using the internal battery.
So not sure if you're suppose to switch the charge ON all the time if using it as a dac/amp for the PC or switch it off, can anyone clarify this?
