I see that I would benefit by using a electric powered usb hub so that I can use my intended to-buy dac and amp for my sennheiser 58x jubilee headphones. I see on Amazon that there are a fair number of them. I also see some of these seem to be "Junk"!
Could someone suggest a good reliable powered hub for me?
I would need such a hub to power my dac and/or amp when the computer is off so that I might then be able to use this system on my ipad, TV and other devices..
