I'm considering getting a pair of beyerdynamic 990 (250ohm version), but due to their high impedance I won't buy them until I have a clear plan on how to amp them. Reading various threads I think that there are two common solutions: 1) the cheap one is using a DAC/amp combo like the fiio e10k, some people say it sounds good, some people say it doesn't 2) the safe one is getting a schiit Modi and magni or similar which I cannot get for less than 250€ (I'm non in US). Maybe below 200 if I look in the used market. Then I thought I could use an old amplifier I have at my parents' house. It's a pioneer a-40, like this one Connecting it to an external DAC such as the schiit Modi, what kind of result can I expect? Thank you!
