Hey, I'm Alex. My first post here. Just gonna say, I have just a very, very, basic knowledge of audio in general, so sorry if I sound like a noob. I recently decided that I was going to purchase the Beyerdnamic DT990 Pro 250 ohms headphones. I also learned that I would need some equipment to power them. Am I going to need just an Amp, or will I also need a DAC. I know a DAC is a Digital-Audio-Converter, but to be honest, I have no idea what it does, so if you could also explain that, it would be very helpful. I already started to look into things and was recommended the Fiio E10K, but researching more, I learned that it's only good up to 100ohms? And since the cans I'm looking at are 250 ohms, thats a no-no since it wouldn't be able to power it to it's full extent? (Like I said, don't know much) I also heard about the Schiit Modi+Magni stack, but that's just too expensive for me. I need suggestions of an Amp and DAC (separate or all in one, like the E10K) for $150, but can be up to $200, that would be able to power these cans to their fullest. I'm not looking for things that I can use for the future, as these headphones will probably be the highest end that I go. Is there anything else that I will need, other than an Amp Thanks a lot, I really appreciate the help.
