Hello, is this the xdsd thread? Does anyone at Ifi actually look at this? Hello?
I just bought a new xdsd from Amazon and I’m wondering if I need to update the firmware? It’s brand new and has a type C charging port. I just want to know which firmware it came out of the factory with, and if it can be checked over blue tooth on Android or iPad? Is it 5.3c GTO? Also, since this is a TRRS jack, I assume this supports both balanced and S-balanced. It states specifically that the two amps maintain discrete grounds right into the 3.5 mm jack, so is it balanced? Also, what’s the formula for determining milliwatts output into say, 80 ohm headphones, single ended and balanced? I’m getting 55 milliwatts and 110 milliwatts respectively, assuming 2.1 volts out s-balanced and 4.2 volts out balanced. I’m using volts squared divided by ohms times 1000 for milliwatts, but I need some verification.
Anyone?
