I'm new to this audiophile stuff, and have a question about a suitable soundcard for me.
I have HD 558 & HD 202 and use them mostly on my PC through a Creative X-FI 5.1 External USB soundcard (the standard one, not 'Pro' or 'HD' version). Now I've read a relatively good reviews on sub-100$ Asus soundcards and a couple of portable DAC/amp combo, and here's the question : Are those soundcards and portable DAC/amp combo can be considered as an upgrade from my current soundcard? Do I gonna notice the improvements?
Right now I'm gathering info about Asus Xonar DSX, Fiio E07K and Musiland Monitor 01 US but desperately need an answer for those questions first.
Thanks in advance.
