Jtinn,
Sadly but true, the stock ST fibers that come with the EMM gears are not up to par with the Aural Symphonics Optimism V2 optical fiber, at least not in my system.
I have been using the Optimism to connect the data port from the CDSD to the DAC for a few months. The stock fibers sounded congested and blurry comparing with the Optimism.
By the way, Aural Symphonics has recently released a new version of the Optimism fibers specifically designed for the EMM Labs gears.
My best suggestion is to try them in your own system before drawing any conclusions. The only trustable expert is your own ears in this case. Let the fibers speak for themselves.
