OK so SOME good news, I can testify that Oluv isn't entirely accurate. He tried thousand dollar DAC and AMPs against smartphones and didn't notice any difference.
While I don't have a Iphone 6s like he does I do have a Samsung S7 Edge Snapdragon which I understand has a very capable DAC I tested it against my motherboard and the smartphone is better sounding.
Against my Xonar DG I first came to the same conclusion Oluv came as in no difference, HOWEVER I fired up Yoshi Horikawa - Fluid song in FLAC and switching back and forth between my Xonar DG and my S7 Samsung I can notice a very much audible difference. The Xonar clearly reproduces all the small audible frequencies in the track that makes it sound "musical" and makes my head shake to the music. The Samsung S7 does NOT do this, these little musical stuff are muffled in the S7
So there is that and it means GOOD news for me. So the question now is if that D30 and Liquid Spark is going to do the exact same thing but even better. At this point I am doubting anything is going to beat this Xonar DG I think we are approaching the limit of the human hearing here at just $30.
Hoping to be wrong, hoping for a clear step above improvement with new DAC and AMP. IT HAS TO, every review I read said how good those DAC and AMP are over sound cards etc It has to be true it just has to be I must know.... I wanted to know over 10 years what good DAC and AMP sounds like so I suppose this is a lesson for my mind to finally be at ease
Fingers crossed, will keep you all posted if I made a good decision or wasted my life's savings.
DAC and AMP arrives either tomorrow or Tuesday.
