Hi guys, I have a quick question that I was hoping some of you guys can shed some light upon. I'm currently in the process of helping my cousin find a good dac upgrade to his current system. He is currently using an Asus Xonar STX soundcard, and while he is happy with it, he is looking for an affordable upgrade if the improvements are worth it. His current headphones is a pair of DT880 600ohm and Sennheiser HD598s. He is planning on possibly picking up a tube amp or hybrid amp later on, so for the time being he is looking for a DAC upgrade over the STX. The choices that we currently have narrowed down to are:
Fiio E17 (seems to be the only one in this range that can do 24/192 via optical)
Have any of you guys used these along with the Xonar STX and can verify whether or not the improvement (if there is one) is worth it? We are also highly considering the E17 for its optical capabilities but not sure how well the wolfson chip stacks up against the AKM and ESS9023.
