I ordered a HAP-S1 from a small Online-Shop in Austria, but theay are not responding. Though I am going to pay more for it, I will probably order it from Amazon.
However, does anyone of you have the experience with any Audio Technica headphone on these? Also I have a Fostex TH600.
I am probably going to use this unit for headphones only. Is it wise to buy this one, or is there a better solution for the money.
