So I recently decided to get into this Hi-Fi thing. It started with just ripping high quality music, but I realized I needed to dig deeper for true audio nirvana. So I recently got a pair of HiFiman HE-400's and I have a Bottlehead S.E.X w/ C4S on the way. So my question now is do DACs and Amps have pairing issues or can I use any ol' DAC with my amp and expect it to sound great? I'm looking for something under $200 with USB and preferably 24/192. I've been looking at the QNKTC – AB-1.2 USB DAC which for $170 looks pretty sweet. Are DAC's all that different? Looking at a lot of DAC spectrum charts it seems they're all flat with a little fall off at the extreme high frequencies. Most emphasis seems to be placed on the amp and hp rather than the source, which leads to believe with the set up I have whether I get the Schiit Modi, JDS O2, or any other DAC as long as I have the bit-rate, depth, and connections I want it doesn't really matter. In this case just USB and RCA out will work for me.
I hope someone can help me out, I already feel I've gone too deep by getting the S.E.X amp, but I'm hoping it will all work out in the end :)
