I have no clue, to pretty much anything, how do i know what dac,s sound better than others? what stats are important? whats the diffrence between expensive dacs and cheap ones. The stats seem the same but the price reallly diffrent. I currently have a superlux 668B. No clue if thats good by general standereds. I like them, think the mids and highs are clear compared to my old headphones, the bass is a bit quiet. ANYWAY. theese are less than £50, what would be a cheap suitable dac for something like this.
