TL;DR: Ive been using a reciever for a power source for headphones. Am I missing out on anything for not using a dac/amp combo?
So I got a nice Pioneer reciever from a thrift shop for $15. It was originally for my 5.1 setup, but I noticed it had a quarter inch headphone jack and tried them with the Hifiman, AKG, and Sennheisers from Massdrop. All of them sounded really good. I even plugged in some okayish sounding earphones into them using the adapter, and it brought out so much detail.
Any of you guys do this and compare it to an amp/dac combo?
