And neither does that mean monster amps - practically any decent amp can spit out 7volts and an extremely clean 2volts and roughly 200mW.
Your Fiio has a DAC. If you can use its line out function then use that as a DAC to another amp. Problem is that older Fiio DAC-HPamps need some kind of adapter on the dock port to enable that, plus a battery powered unit if it's old enough would have an older battery too. So it won't be a bad idea to get a new DAC.
As for the Darkvoice, well, you'd need an amp, whether it's an amp by itself or in the same box as the DAC like your Fiio now. It's just one of the more popular ones and I wouldn't shy away from that OTL amp since it has a low noise floor for an amp that price (that is, if you exclude the O2).
Great value for the money. And if it matters to you, it's kind of like the Corvette - made in the USA and you don't have Chinese labourers jumping off the factory roof. Schiit makes America great again, except of course it's not like they have a whole horde of factory workers there.
Great explanations on all points, thanks!
Shiit sounds like the kind of company I like to buy from... Every chance I get, I like to by made in the US or at least NOT made in China. It looks like Shiit's pricing is really good for what appears to be quality product and solid output. I might try out a Shiit Magni 2 as a budget friendly approach and upgrade from there if needed.
