I just recently imported the JDS O2 headphone amp and tried to connect it to my MF VDACII. At last I connected the vdac via spdif to my pc and via rca out to my desktop amp and the loudspeakers. Now I want to use my headphones with this amp. I connected the dac via spdif to the pc and the dac via rca to 3.5 jack adapter to the input of the jds o2. But there is no sound, just some background noise. The O2 works great amplifying other sources. The problem seems to be something referring to the dac output or rca to 3.5 adapter. Here I've got the link to the adapter: http://www.amazon.de/gp/product/B00183R2Z4/ref=olp_product_details?ie=UTF8&me=&seller=
Right now, I dont know, what i could have done wrong. Do you have any idea? Is there any problem with my plan to connect these devices?
Thank you very much in advance,
