I was recently having a chat with an experienced Headfi poster regarding my system which I am in he process of upgrading (new amp) and they were advising me that I might be limiting my systems performance because of my DAC's onboard USB-S/PDIF interface.
They were recommending that I purchase a separate USB-S/PDIF converter to place between my iMac and DAC like these:
My current DAC, a Grace Design m903 has up to 24/192 USB class 2 audio and asynchronous transfer mode licensed from Gordon Rankin (Wavelength Audio capability http://www.usbdacs.com/Concept/Concept.html). It is my understanding that this was considered very good technology in terms of jitter management/elimination.
iMac running iTunes or Decibel playing material between 16/44 to 24/96
Grace Design m903 connected via USB
DNA Stratus 2A3 connected via unbalanced cables
One of these units would go between the iMac and the DAC with USB into the converter with S/PDIF cable connected to the DAC. Can someone kindly explain to me why these units will improve my sound over my units current inboard capability?
