hello people, Recently my Shure srh940 broke and I've started to look up some new headphones to mix and master with in my home studio. I've decided to go with the AKG k702 but I saw that a lot of people said they need a good amplifier with them to really use them to they're full potential. So I started to look up some amps and found the Matrix M-Stage, Schiit Asgard, HiFiMAN EF-5 and others and then i saw that they need a DAC to connect to my PC which i'm using to make music, and some people said just upgrade your audio interface instead of investing in an amp and a DAC. i saw somewhere that we need to have a mixer to connect the amp and audio interface, so i got lost and i don't know what i need to get and how i need to connect everything. Do i need only the amplifier and should i try to connect it to my audio interface? Should i get an amplifier and a DAC as well? Does the amplifier and DAC replace my audio interface or should i get all three of them together? Do i need a mixer to connect everything up? I'm really lost here and i would appreciate some guidance with explaining those fundamental things before i make such a big purchase. thanks in advance and sorry for my English. Dave.
